Microsoft Flight Simulator

Microsoft Flight Simulator remains one of the heaviest mainstream workloads a gaming PC can face, and the pairing of AMD's Ryzen 9 5950X with NVIDIA's GeForce RTX 3080 sits in an interesting spot for it: strong enough to push high frame rates at 1080p and 1440p, but constrained enough at 4K that settings selection starts to matter. The data below walks through measured frame rates, resolution scaling, and how this combination ranks against the wider field of tested hardware.

Similar Performance Alternatives

Looking for hardware that would deliver a similar experience starts with the CPU side. The Ryzen 9 5950X posts an average benchmark score of 51947, placing it in the 91st percentile of all CPUs in the database. Its nearest rivals are remarkably close: the Intel Core Ultra 5 235HX averages 52073 (0.2% ahead), the AMD EPYC 8124P averages 52121 (0.3% ahead), the Intel Core i9-13900F averages 51730 (0.4% behind), and the Intel Core i7-14700 averages 52301 (0.7% ahead). All four sit within a fraction of a percent of the 5950X in aggregate scoring, so any of them would behave comparably as the processor half of this combo.

That proximity is worth pausing on. A 0.7% spread across five different CPUs from different vendors and generations means CPU-side substitutions barely move the needle in aggregate workloads. For a flight simulator, where per-thread responsiveness matters alongside raw throughput, the 5950X's single-thread figures are also relevant: 944 in 3DMark single-thread, 1614 in Cinebench R23 single-core, and 2083 in Geekbench single-core. Its multi-thread credentials are equally strong, with a Cinebench R23 multi-core score of 26017 and a Geekbench multi-core score of 15233 — headroom that Microsoft Flight Simulator's streaming and world-data threads can draw on.

On the GPU side, the RTX 3080 averages 23172 across its benchmark suite, landing in the 68th percentile of all GPUs. Its nearest rivals by average score are an eclectic set: the NVIDIA P106-100 at 23249 (0.3% ahead), the AMD Radeon Pro Vega 16 at 23250 (0.3% ahead), the AMD Radeon RX 6600M at 23273 (0.4% ahead), and the AMD Radeon R9 M290X at 23276 (0.4% ahead). These aggregate scores cluster tightly, but aggregate placement blends compute, OpenCL, and older API tests, so for a modern DirectX 12 Ultimate title the RTX 3080's specific strengths — a PassMark G3D score of 25086, 8704 shading units, 68 RT cores, and 29.77 TFLOPS of FP32 throughput on the 8 nm GA102 chip — are more telling than the blended average suggests. A system built around any of these rival GPUs would land in a similar overall database percentile but may not match the 3080's DirectX 12 performance profile.

CPU and GPU Roles

Which component limits this game depends heavily on resolution, and the measured data makes the scaling pattern clear. Moving from 1920x1080 to 3840x2160 at Ultra drops the average from 89.3 FPS to 48.6 FPS — a 45.6% reduction. At Low settings the drop is steeper in relative terms, from 155.7 FPS to 91.9 FPS. That kind of resolution sensitivity indicates the GPU is the primary bottleneck once pixel counts rise.

The CPU-side evidence supports this. At 1080p, the frame rate ceiling appears to sit well below what the RTX 3080 could deliver in less CPU-bound titles: 155.7 FPS at Low is the maximum measured figure anywhere in the dataset. Flight Simulator's world simulation, air traffic, and scenery streaming lean on the processor, and the 5950X's strong single-thread and multi-thread results keep that ceiling as high as it realistically gets for this title. In short: at 1080p and 1440p, the CPU and game engine set the ceiling; at 4K, the RTX 3080's 10 GB of GDDR6X and its 760.3 GB/s of memory bandwidth become the limiting factor, and settings must be trimmed accordingly.

The settings scaling confirms the picture. At 4K, each preset step matters a great deal — Low delivers 91.9 FPS while Ultra manages only 48.6 FPS, a gap of 43.3 FPS across the preset range. At 1080p the same range spans 66.4 FPS (155.7 down to 89.3), a much smaller proportional drop, again consistent with a CPU/engine ceiling capping the top end.

Measured FPS Breakdown

All figures below are measured averages from the database; minimum and maximum frame rates were not recorded for these runs.

At 1920x1080:

• Low: 155.7 FPS average
• Medium: 121.2 FPS average
• High: 90.6 FPS average
• Ultra: 89.3 FPS average

Note how close High and Ultra are at this resolution — just 1.3 FPS apart. Once the CPU/engine ceiling is reached, visual quality beyond High is essentially free at 1080p.

At 2560x1440:

• Low: 127.2 FPS average
• Medium: 99.5 FPS average
• High: 75.8 FPS average
• Ultra: 72 FPS average

The same pattern repeats. High to Ultra costs only 3.8 FPS, while Low to Medium costs 27.7 FPS. The expensive steps are the lower presets; the top of the stack is nearly flat.

At 3840x2160:

• Low: 91.9 FPS average
• Medium: 72.5 FPS average
• High: 52.2 FPS average
• Ultra: 48.6 FPS average

Here the curve changes shape. Every preset step carries a real cost: 19.4 FPS from Low to Medium, 20.3 FPS from Medium to High, and 3.6 FPS from High to Ultra. The Medium-to-High step is where the 60 FPS line is crossed — High lands at 52.2 FPS, below the playable threshold, while Medium holds 72.5 FPS. Only at 4K does this hardware have to make a genuine settings trade-off.

FAQ

Q: Can the Ryzen 9 5950X + RTX 3080 run Microsoft Flight Simulator at 4K?

A: Yes, but not at every preset. At 3840x2160, Low (91.9 FPS) and Medium (72.5 FPS) clear the 60 FPS threshold, while High (52.2 FPS) and Ultra (48.6 FPS) fall short. Medium is the best playable setting at 4K.

Q: Can this combo max out the game at 1440p?

A: Yes. Ultra at 2560x1440 averages 72 FPS, comfortably above 60, so all four presets are playable at that resolution.

Q: How much faster is 1080p Low than 4K Ultra?

A: 1080p Low averages 155.7 FPS versus 48.6 FPS at 4K Ultra — the lightest load runs at more than three times the frame rate of the heaviest.

Q: Is the RTX 3080 a strong GPU by database standards?

A: It sits in the 68th percentile of all GPUs with an average benchmark score of 23172, and a PassMark G3D score of 25086 — upper-tier, though not at the extreme top of the chart.

Q: Is the Ryzen 9 5950X overkill for this game?

A: Its 16 cores and 32 threads exceed what the game strictly needs, but its single-thread performance (944 in 3DMark single-thread, 1614 in Cinebench R23 single-core) is what keeps the frame rate ceiling high in a simulation-heavy title like this one.

Q: Does raising settings from High to Ultra cost much performance?

A: Barely at 1080p (90.6 to 89.3 FPS) and 1440p (75.8 to 72 FPS), but at 4K the game is already GPU-limited at High, so the extra cost there is only 3.6 FPS — the real cliff is between Medium and High at 4K.

Best Settings per Resolution

Using 60 FPS average as the playable threshold, the most demanding preset that stays at or above the line at each resolution:

• 1920x1080 — Ultra: 89.3 FPS average. No compromise needed; even the top preset clears the threshold by nearly 30 FPS.
• 2560x1440 — Ultra: 72 FPS average. Again, the maximum preset is playable, with 12 FPS of headroom over the threshold.
• 3840x2160 — Medium: 72.5 FPS average. Ultra (48.6 FPS) and High (52.2 FPS) both miss the mark, so Medium is the ceiling at 4K.

How This Combo Ranks

Within Microsoft Flight Simulator specifically, this CPU/GPU pairing ranks 1079 out of 3714 tested combinations — roughly the top 29% of configurations in the database for this game. That placement is consistent with the component-level percentiles: a 91st-percentile CPU paired with a 68th-percentile GPU produces a combo that is clearly above the middle of the field but not elite, and in a GPU-heavy title like this one the graphics card's relative standing dominates the outcome. The rank also contextualizes the 4K results: combinations above this one in the rankings are the ones likely to hold 60 FPS at 4K High or Ultra.

The Verdict

Yes, this PC can run Microsoft Flight Simulator — with one caveat tied to resolution. At 1920x1080, every preset from Low through Ultra is playable, topping out at 89.3 FPS on Ultra with a 155.7 FPS ceiling on Low. At 2560x1440, the verdict is identical: all presets playable, Ultra averaging 72 FPS. At 3840x2160, the picture narrows — Low (91.9 FPS) and Medium (72.5 FPS) stay above 60 FPS, while High (52.2 FPS) and Ultra (48.6 FPS) do not, making Medium the best setting for a 4K display. For a flight simulator with this level of world detail, those are strong results for a combination ranked 1079 of 3714, and the near-flat cost of Ultra over High at 1080p and 1440p means players at those resolutions can simply max the game out.
