Best Cpu For Microsoft Flight Simulator

Since the release of Microsoft Flight Simulator 2020 we've put the PremiumBuilds test rig to piece of work, analyzing the factors that have the most impact on functioning in this sim. In this article, we'll discuss what nosotros've found and use the data to inform component recommendations – such as the CPU, GPU and memory – so that you can be sure of getting the all-time operation in Flight Simulator 2020.

GPU killer, CPU hater, or just obviously badly coded?

There's been a lot of talk most Flying Simulator 2020's performance since its release, and not all of it has been positive. In detail, people have pointed to benchmarks and testing showing frame rates in the mid xl's on high-end hardware – indeed the highest-finish hardware, and claimed that the game is a dog, or that no PC can run it well. This is unfair. It's perfectly possible to specify a system that runs this game fluidly and at acceptable frame rates. It's a more involved process than for a 'normal' gaming PC though: there are interdependent factors at play and imbalances between components or incorrect settings can  be detrimental to the feel. This article uses the data to help y'all empathize exactly what makes this sim tick.

Simulators: They're not only toys.

The first major issue is that whilst it can be achingly beautiful Flight Simulator 2020 is a simulator, not a game in the traditional sense. There is a complex flying model running backside the scenes, calculating the physics that dictate whether you're flying or falling. Ultimately it is this physics model that constrains performance. Our testing shows that the game uses merely 4 threads (and yet tin still max out 8 core CPUs at times) and operation is primarily dependent on the single-core speed of the CPU.

That said, no electric current hardware will exceed around 60 FPS in this game using the full flying model. Frame rates are variable and we conducted our testing under the most challenging weather condition considering these place the biggest demands on the underpinning hardware. Where we've demonstrated a playable 35FPS over a busy urban center it translates to a buttery smooth l FPS+ flight high over less complex terrain on the same configuration. There are also still some consistency issues particularly as the sim initializes at a busy aerodrome or when you overfly a complex urban expanse. You lot shouldn't be surprised to see frame rates in the low teens in this situation but it smooths out after a few seconds. We experienced this beyond almost all configurations and have witnessed it in others testing too so it appears to be an ingrained issue with the lawmaking, non the hardware. Hopefully, such performance inconsistencies will be ironed out as the sim matures. In particular, it relies on the aging Direct X 11 API, 1 of the reasons it's so constricted to 4 cores. At that place is a planned migration to DX12 in future and we're hopeful this will bring substantial optimizations with it.

With those expectations set up, let's dig into the numbers and see what we can learn:

The testing protocol:

Every exam in this commodity followed the same blueprint. Using an A320 we took off from JFK Aerodrome, climbing to 2000 feet, flying towards Manhattan and so turning left to overfly Manhattan before ending logging over the Statue of Freedom in a flying lasting 3 minutes. This is arguably a 'worst case' scenario for Flight Simulator 2020 with an airliner over a busy metropolitan surface area and many users accept reported NYC 'unplayable'. Each exam was conducted in order to isolate the variable under test: For the CPU tests nosotros ran an RTX 2080 Ti GPU at 1080p and high graphics settings ensuring that the system was entirely CPU bound throughout the flight. When testing GPUs we used our Ryzen 3600 test organisation with 16Gb RAM at 3600MHz. The Ryzen 3600 was chosen for two primary reasons: Firstly information technology's more representative of the CPU that most people will be running. Secondly it demonstrated more than consistency than the pure 8 cadre i7-9700K, probably because of the flexibility of the 6 physical and half-dozen additional logical cores made available via multithreading. Ram testing besides used the Ryzen CPU owing to the known benefits of RAM speed with Zen two CPU'due south but kept the GPU and game settings the same.

Flight Simulator 2020 CPU scaling

We can see in the graph above the impact of CPU functioning, from a Ryzen 3100 analogue (in fact the Ryzen 3600 with two cores disabled) to the 6 core 12 thread Ryzen 3600, followed by the 8 core Intel i7-9700K in diverse states of overclock. The broad pattern is consistent with game performance closely tied to CPU performance only at that place are a couple of features of interest. Firstly note that the 4C/8T CPU suffers terrible operation in Low, 1% Low, and 0.one% low metrics: This is indicative of the playing experience with large and frequent stutters, lag and spikes. Despite this for the about part the game was playable with the shipping controllable but it is far from ideal.

Dissimilarity those results with the six-core, 12-threaded Ryzen 3600: Here nosotros encounter a small increase in pinnacle and boilerplate FPS, simply a marked improvement in the Depression and 1% Low metrics, from 10-12FPS to 26 and xx FPS respectively. This manifests in a much more than consistent playing experience with shine framerates and little stutter. Note that the 0.1% lows remain in the basement, at eight FPS: They will get a consequent characteristic of this analysis whenever a CPU limit is encountered.

Moving to the Intel i7-9700K, this chip has been on the podium of gaming CPU's throughout 2019 and the kickoff one-half of 2020 with just the i9-9900K and now the Comet Lake iterations superseding it. Information technology marginally outperforms the Ryzen 3600 in Flight Simulator 2020 at stock speeds simply still suffers from rock bottom 0.1% lows. Overclocking it to four.7GHz and and then 4.9GHz sees a pocket-size improvement proportional to the increased clock speed and chiefly an comeback in 1% and 0.1% Lows – the CPU is being maxed out less often at this higher clock speed. This allows the states to draw the conclusion that FS2020 peak performance is indeed dictated by the CPU, and primarily past the CPU's individual cadre speed and not necessarily the full CPU performance.

Logging CPU usage throughout testing rarely saw whatever CPU exceed 60% utilization. Nevertheless, logging on a per core ground sees individual cores hitting their limit at 95%+ utilization. Occasions where all active cores go swamped correlates to those instances of 0.1% Lows in frame rates. This is visible on the graph beneath: The dotted lines stand for lesser used cores, the dashed lines the more prominently used cores that are running the game code. On 2 occasions here we see spikes towards total CPU utilization denoted by the solid ruby-red line. These instances correlate to several seconds of very low functioning with long frame times and stutter and is the source of those shockingly low 0.1% lows when CPU limits are reached.

Simply put, when the CPU tin't cope with the game engine, it stalls and we encounter a huge spike in frame time as the GPU sits and waits for data to render the side by side frame. See videos of a Ryzen 3950X making simply 44FPS in FS2020 whilst showing under 20% utilisation? At present you know why. This Sim cannot use more than four cores.

CPU Scaling Conclusions

Microsoft Flight Simulator needs a combination of adequate cores and the highest individual cadre speeds possible. The Ryzen 5 3600 performs admirably and would be our recommendation for anyone building on a budget. Mid-tier processor recommendations go to the Ryzen 7 3800X due to its 8c/16t topology and 4.5GHz heave speed, and the Intel Core i5-10600K due to its even higher single-cadre capability and hyperthreading. At the high end we recommend the Intel Cadre i7-10700K or the i9-10900K – and if you're serious about squeezing every final frame out of Flying Simulator 2020 – then a strong cooling solution and some fourth dimension spent overclocking is well-advised no thing what CPU y'all opt for.

Flight Simulator 2020 GPU Scaling – 1080p

Examining GPU performance in Flight Simulator 2020 allows us to further explore the relationship between GPU ability and CPU capability. Information technology is ofttimes said that this game needs a very powerful GPU to run well but that can really lead to significant functioning issues if the underlying mechanisms aren't understood. This is a sim where turning your graphics settings up can actually better functioning!

In these tests nosotros used the Ryzen 3600, 16b of Ram at 3600Mhz CL15, and the GPUs every bit described without overclock. Nosotros ran the game at 1080p, High settings with photogrammetry on. We flew our standard flight path over NYC and logged the data.

These results may wait counter-intuitive at first but consider them in context of the CPU operation limits we discovered in the section above.

The GTX 1660 Super performs well hither with acceptable boilerplate frame rates and importantly for the playing experience relatively high 1% and 01.% lows. Of all the testing done these runs stood out every bit the about fluid. The secret? This gear up is completely GPU bound. The GPU utilization sits at 95% or above, showing that it's the GPU and not the CPU and thus game engine that is limiting the speed of the simulation. This results in smoothen consistent frame rates.

Moving to the EVGA RTX 2060 KO, a significantly more powerful GPU nosotros see an increase in average and maximum frame rates merely this is at the expense of the 1% lows and particularly the 0.i% lows which are sub 10FPS. This is embodied in gameplay as noticeable stutters and hangs that were not nowadays when using the GTX 1660 Super.

The tendency continues every bit we footstep upwardly to the big guns. Both the GTX 1080 Ti and RTX 2080 Ti show very low 0.ane% rates of just i and 8 FPS respectively. And so what is happening here?

It comes down to the trade-off between CPU and GPU performance. Both the GTX 1080 Ti and RTX 2080 Ti are criminally underutilized at 1080p and this means that the CPU is working flat out and frequently hits pinnacle capacity. The GPU is left waiting for data and the upshot is a frustrating and hasty experience at times. Annotation that despite the biggy rendering power of the RTX 2080 Ti we cannot exceed the ultimate operation limiter: the CPU. When that happens it results in lag, stutter and an ugly playing experience.

Flying Simulator 2020 GPU Scaling -1440p

Here nosotros've moved up to 1440p resolution which is a common resolution in Sim rigs owing to the need for an increased level of particular to view cockpit instrumentation. Of form, the virtual world build past Asobo comes alive at this resolution too, and the demands on the graphics processor increase greatly.

The GTX 1660 Super struggles at 1440p. We don't approach a CPU limit with utilization around 40%. The poor minimum, ane% Low and 0.one% low framerates are all the result of a GPU that's incapable of keeping upward. Stepping up to the RTX 2060 KO we see it come into its element at this resolution and settings, assuasive the CPU to be virtually fully utilized but never smacking off of the performance ceiling and inducing stutters. This can be seen in the healthy 1% and 0.1% low numbers. This GPU gave slick playable results at these settings with a Ryzen 3600 much equally the GTX 1660 Super excelled at 1080p high settings.

Moving up to top tier GPUs again does picayune for performance: in fact information technology hurts the low finish a little equally we encounter occasional CPU limitations which bring smooth play to a halt. The RTX 2080 Ti sees the highest average and high FPS rates at fifty FPS and 60.seven FPS respectively but drops 0.1% lows to thirteen.3 FPS versus the RTX 2060 KO's 17.8FPS in that metric. Information technology still provides a smooth and playable feel but we really benefit from a motility upward to ultra settings here, increasing the load and smoothing the framerate.

These results highlight the frail residual that needs to be struck when selecting a GPU for Flight Simulator 2020. You need to be sure of your target resolution and settings as well as the operation limitations of your CPU prior to deciding on the best GPU. The saving grace here, of course, is that settings can be tweaked to perfectly balance GPU load and have the heat off of the CPU. So equally long every bit your GPU is in the correct performance bracket you tin can fine-melody it to your taste and to eliminate CPU leap situations.

Our GPU Recommendations for Flying Simulator

To conclude the GPU testing department here are our GPU Recommendations for Flight Simulator 2020:

• 1080P – The GTX 1660 Super provides excellent functioning at 1080p high, whilst the Radeon RX 5600XT and RTX 2060 will perform well at Ultra settings. GPUs with more performance than this may actually induce worse playability unless you accept a top tier CPU to support them.
• 1440p – Nosotros recommend an RTX 2060 Super, RTX 2070 Super, or the Radeon RX 5700XT for best performance and the ability to enjoy this sim at high or ultra settings.
• 1440P Ultrawide: An RTX 2080 Super or RTX 2080 Ti provide excellent performance at this resolution on Ultra settings.
• 4K: At 4K an RTX 2080 Super, RTX 2080 Ti, or one of the new Ampere GPUS is required for adequate performance on high settings.

Flight Simulator 2020 Ryzen RAM Scaling – Speed and capacity

AMD's Ryzen processors have always been sensitive to RAM speed. The most recent Zen 2 parts are no exception and we've demonstrated how operation scales with optimally selected RAM.

In these tests we ran the organisation at 1080p with the RTX 2080 Ti to isolate CPU performance.

Worst case scenario is 'default' JDEC speeds of 2133 MHz. We tin see this costing 10FPS or virtually 20% on boilerplate and maximum frame rates. 2666 MHz CL16 performs acceptably well is around 5 FPS or 10% down on improve-optimized RAM. From 3000 MHz CL14 to 3600MHz CL14 speeds are less critical although 3600MHz posts the fastest average and maximum frame rates, information technology loses out to the 3000 Mhz ram in Minimum and 1% lows. It's non clear exactly what causes this from the testing we've conducted but the results are on par across the higher speeds from 3000MHz to 3600MHz.

The overall trend here is a useful counterpart for the general point about the importance of CPU core speed in Flight Simulator 2020. You certainly need optimized ram to allow the CPU to perform to its potential and be sure to enable the RAM speed profile in BIOS!

16GB vs 32GB RAM for Flying Simulator

We tested three RAM configurations as Microsoft recommend 32GB for Flight Simulator 2020. We ran tests of 32GB 3000MHz CL15 ram in 2x16GB dual-channel mode confronting 2x8GB  at the same speed. We also tested a unmarried 16GB stick, necessitating single-channel operation.

There was no discernable performance difference betwixt the two capacities, in fact 16Gb slightly out performed 32GB but not beyond margin of error. Interestingly when 16Gb was installed utilization hovered between 12 and 14GB, whilst with 32GB installed utilization reported between 16.5GB and 18.5GB: The game clearly tin can employ more ram perhaps for pre fetching assets or textures but in that location doesn't appear to be a huge deviation in performance. The single aqueduct 16Gb stick performed worst as expected nearly 10% behind the dual channel configurations. With ram prices dropping information technology seems sensible to purchase a 32GB kit for this sim if the budget allows, merely if it comes to a choice between 32GB RAM or a improve CPU or GPU, we'd accept the upgraded core components and 16GB. 32Gb will exist required if you intend on doing any grade of multitasking whilst running the simulator.

RAM Recommendations for Flying Simulator

For Ryzen 3600Mhz CL16 RAM is optimal (see our upcoming Ryzen RAM performance assay article), and Flight Simulator 2020 is no exception. If you lot're on a budget 16Gb doesn't appear to injure performance at all, but 32GB adheres to the developers recommendations and may prove sensible. We'd certainly recommend 32GB if you lot intend on expanding the game with modifications and additional avails, or running on a high-end CPU and GPU combination. To partner an Intel CPU, nosotros'd recommend 3000MHz CL15 or faster RAM in a 2x16Gb kit.

Conclusion: Building the best PC for MS Flight Simulator 2020

In order of importance the factors that enable good performance in Flying Simulator 2020 are:

1. A high-performance CPU with at to the lowest degree 6 and preferably 8 cores and multithreading.
2. A current-generation GPU capable of good operation specific to the target resolution.
3. Ideally 32Gb of speed optimized RAM in dual channel fashion.
4. An SSD – for load times rather than outright performance

Critically, the CPU and GPU must exist advisedly balanced to work in harmony. The CPU dictates the ultimate operation ceiling of the simulator whilst the GPU must be capable of matching the framerate at the desired settings. If you're experiencing ugly stutters, you may observe that increasing your graphics settings cures them! Alternatively, the 20, 30 and 60fps frame charge per unit caps can artificially limit frame rates to give the CPU animate space. If all else fails nosotros'd propose experimenting with those settings. You may have to cede average frame rates for consistent frame times.

Ultimately Flight Simulator 2020 is a simulator that volition tax the highest-end hardware currently available at high settings and resolution, simply it will also run very well on mid-range equipment. To label it equally poorly coded or unplayable is grossly unfair. Our all-encompassing testing shows that with the sweet spot of hardware y'all will enjoy fluid, immersive play with utterly bewitching graphics and the full flight simulator experience. It needn't toll the earth to exist able to fly the world.
