Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding flight sim that stresses both processor and graphics card, and the combination of the AMD Ryzen 7 5700X3D with the NVIDIA GeForce RTX 4080 proves to be a remarkably balanced pairing across all tested resolutions. The data shows this combo ranks 383rd out of 3,714 tested combinations, placing it in the top 11% of all systems, which is a strong indicator of its overall gaming capability. The measured FPS results reveal that the RTX 4080 is the primary scaling factor as resolution increases, while the 5700X3D’s large 96 MB shared L3 cache provides the consistent frame pacing needed for a simulation that frequently relies on CPU-bound terrain and physics calculations.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial, but the pattern across settings reveals where the bottleneck shifts. At 1080p with Low settings, the combo delivers 157 FPS, which drops to 146 FPS at 1440p and further to 125 FPS at 4K. That is a 20% reduction from 1080p to 1440p and a 14% reduction from 1440p to 4K, indicating that even at Low settings, the GPU is still the limiting factor at higher resolutions. The RTX 4080’s 16 GB of GDDR6X memory and 716.8 GB/s bandwidth are being tasked with more pixels, and the data confirms that the framerate scales almost linearly with pixel count.

Moving to Medium settings, the pattern changes slightly. At 1080p, the combo hits 143 FPS, at 1440p it reaches 132 FPS, and at 4K it drops to 97 FPS. The 1080p-to-1440p drop is only 8%, while the 1440p-to-4K drop is 27%. This suggests that at 1080p Medium, the CPU is beginning to play a more significant role, as the Ryzen 7 5700X3D’s 8 cores and 16 threads are handling the simulation logic while the GPU keeps up with the moderate load. The 4K Medium result of 97 FPS shows the GPU taking over as the primary constraint, since the pixel throughput demand exceeds what the CPU can feed at lower resolutions.

At High settings, the trend becomes more pronounced. The combo achieves 123 FPS at 1080p, 99 FPS at 1440p, and 73 FPS at 4K. The 1080p-to-1440p drop is 20%, and the 1440p-to-4K drop is 26%. This consistent degradation points to the GPU being the dominant bottleneck across all resolutions at High settings, with the RTX 4080’s boost clock of 2505 MHz and 48.74 TFLOPS FP32 performance being pushed harder as resolution scales. The 4K High result of 73 FPS is still playable, but the margin over the 60 FPS threshold is thinner than at lower resolutions.

Ultra settings show the largest absolute drops. At 1080p, the combo delivers 117 FPS, at 1440p it falls to 95 FPS, and at 4K it bottoms out at 70 FPS. The 1080p-to-1440p drop is 19%, while the 1440p-to-4K drop is 26%. The 4K Ultra result of 70 FPS is the lowest measured in the entire dataset, but it remains above 60 FPS, which is respectable for a flight simulator with complex scenery. The fact that the 4K Ultra score is only 3 FPS lower than the 4K High score (70 vs. 73) suggests that the RTX 4080 is nearing its limits at 4K Ultra, and additional settings increases would likely push it below 60 FPS.

The scaling behavior indicates a well-balanced system overall. At 1080p Low (157 FPS) versus 4K Low (125 FPS), the GPU is clearly the limiter, as the CPU has headroom to spare. However, at 1080p Ultra (117 FPS) versus 4K Ultra (70 FPS), the GPU is even more dominant, with a 40% performance drop. This is typical for a GPU-centric title at higher resolutions. The Ryzen 7 5700X3D, with its 3.00 GHz base clock and 4.10 GHz boost clock, provides enough single-thread performance for the simulation’s main thread, while its 96 MB L3 cache helps with the repeated access to terrain data. The data shows that the combo never becomes CPU-bound at any resolution in this test, which confirms the CPU’s efficiency.

Settings Recommendations

For the best experience per the measured rows, Medium settings at 1440p appear to be the sweet spot. The combo delivers 132 FPS average with a minimum of 112 FPS and a maximum of 152 FPS at 2560x1440 Medium. This provides a smooth, high-refresh experience with enough visual fidelity to appreciate the scenery without sacrificing performance. The 112 FPS minimum ensures that even dense urban areas or complex weather effects won’t cause noticeable stutter. At 1080p Medium, the 143 FPS average with a 122 FPS minimum is even better, but the visual upgrade to 1440p justifies the small drop for most users with a 1440p display.

If you prefer maximum visual quality, 4K Medium at 97 FPS is a viable option. The 83 FPS minimum at 4K Medium is still above the 60 FPS threshold, and the 112 FPS maximum shows the system can burst higher during less demanding moments. However, 4K High at 73 FPS and 4K Ultra at 70 FPS are both playable, but they lack the headroom for consistent frame pacing. The data shows that the jump from Medium to High at 4K costs 24 FPS (from 97 to 73), while the jump from High to Ultra costs only 3 FPS (from 73 to 70). This suggests that High settings at 4K provide diminishing returns over Medium, and Ultra is barely worth the extra GPU load.

At 1440p, High settings at 99 FPS are a solid choice if you want better shadows and textures than Medium. The gap between Medium (132 FPS) and High (99 FPS) is 33 FPS, which is noticeable on high-refresh monitors. But the 95 FPS at 1440p Ultra is only 4 FPS lower than High, making Ultra the better pick if you’re already at 1440p and want the highest fidelity. For 1080p users, Ultra at 117 FPS is the clear recommendation, as it provides the best visuals while still maintaining a framerate above 115 FPS. The 1080p Low result of 157 FPS is unnecessary unless you’re chasing maximum competitive performance, which is rare in a flight sim.

The data reveals that the most efficient setting-to-performance ratio is Medium across all resolutions. At 1080p, Medium (143 FPS) is only 14 FPS slower than Low (157 FPS) but offers substantially better visuals. At 1440p, Medium (132 FPS) is 14 FPS faster than High (99 FPS) and only 14 FPS slower than Low (146 FPS). At 4K, Medium (97 FPS) is 28 FPS faster than High (73 FPS) and 28 FPS slower than Low (125 FPS). This consistent pattern suggests that Medium is the default recommendation for this combo, with High or Ultra reserved for users with G-Sync or FreeSync displays that can handle variable refresh rates.

How This Combo Ranks

The comboRankInGame of 383 out of 3,714 places this system in the 89.7th percentile of all tested combinations. That is a strong showing, but the nearest CPU rivals provide context. The AMD Ryzen 5 7600X3D has an average benchmark score of 24,728, which is 0.1% higher than the Ryzen 7 5700X3D’s 24,709. This negligible difference means the two CPUs perform nearly identically in general workloads, and the 5700X3D’s 8 cores and 16 threads don’t offer a meaningful advantage over the 7600X3D in this test. The AMD Ryzen 9 5900HX scores 24,822, which is 0.5% higher, while the Intel Core i5-12450HX scores 24,576, which is 0.5% lower. The Intel Core i5-11600 at 24,563 is 0.6% lower.

On the GPU side, the RTX 4080’s average benchmark score of 54,247 is nearly identical to the RTX 4080 SUPER at 54,209 (0.1% higher). The AMD Radeon Pro W5700X scores 54,828, which is 1.1% higher, while the AMD Radeon RX 6750 GRE 12 GB scores 55,698 (2.6% higher) and the AMD Radeon 8060S scores 55,757 (2.7% higher). This indicates that the RTX 4080 is slightly below some rivals in raw synthetic benchmarks, but the measured FPS in Microsoft Flight Simulator tells a more nuanced story. The combo’s rank of 383 suggests that the pairing is well above average, but not elite. The top 10% of combos likely include newer GPUs like the RTX 4090 or RX 7900 XTX, but the data only provides the rank, not the specific competitors.

The CPU’s percentileVsAllCpus of 77 means it outperforms 77% of all CPUs tested, which is solid for a 2024 release. The GPU’s percentileVsAllGpus of 86 is higher, indicating that the RTX 4080 is a stronger component relative to the CPU. This asymmetry explains why the combo rank (89.7th percentile) is close to the GPU percentile but below the GPU’s synthetic score percentile. The 5700X3D’s 96 MB L3 cache is a key differentiator for flight sims, as it reduces memory latency for terrain streaming, but the CPU’s overall multithreaded score (23,366 in Cinebench R23) is modest compared to newer CPUs.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest framerates. Low settings produce 157 FPS average, Medium produces 143 FPS with a minimum of 122 FPS and a maximum of 165 FPS, High produces 123 FPS, and Ultra produces 117 FPS. The spread from Low to Ultra is 40 FPS, which is the largest relative gap across all resolutions, indicating that the GPU has headroom at 1080p. The 122 FPS minimum at Medium is particularly strong, ensuring smooth gameplay even in complex scenes. The 165 FPS maximum at Medium shows the system can burst to very high framerates when the sim isn’t loading new terrain.

At 2560x1440, the performance scales down as expected. Low settings deliver 146 FPS, Medium delivers 132 FPS with a minimum of 112 FPS and a maximum of 152 FPS, High delivers 99 FPS, and Ultra delivers 95 FPS. The drop from Low to Medium is only 14 FPS, but the drop from Medium to High is 33 FPS, which is significant. The 112 FPS minimum at Medium is still above 100 FPS, making 1440p Medium a very comfortable experience. The 152 FPS maximum at Medium indicates that the system can handle less demanding moments with ease.

At 3840x2160, the GPU is clearly the bottleneck. Low settings produce 125 FPS, Medium produces 97 FPS with a minimum of 83 FPS and a maximum of 112 FPS, High produces 73 FPS, and Ultra produces 70 FPS. The 4K Low result of 125 FPS is impressive, showing that the RTX 4080 can handle 4K at low fidelity without breaking a sweat. The 4K Medium result of 97 FPS is the most balanced 4K option, as it stays above 90 FPS. The 4K High result of 73 FPS and 4K Ultra result of 70 FPS are both playable, but they lack the headroom of Medium. The 83 FPS minimum at 4K Medium ensures that even the heaviest scenes won’t drop below 80 FPS, which is excellent for a flight sim.

The data shows a clear trend: the gap between Low and Ultra narrows as resolution increases. At 1080p, the gap is 40 FPS (157 vs. 117). At 1440p, the gap is 51 FPS (146 vs. 95). At 4K, the gap is 55 FPS (125 vs. 70). This widening gap confirms that the GPU’s rendering workload becomes more dominant at higher resolutions, while the CPU’s contribution to the framerate diminishes. The Ryzen 7 5700X3D’s 3.00 GHz base clock and 4.10 GHz boost clock are sufficient to keep up with the RTX 4080 at all resolutions, but the GPU’s 16 GB of VRAM and 716.8 GB/s bandwidth are the primary factors in the 4K results.

GPU Role

The NVIDIA GeForce RTX 4080 plays a critical role in this combo’s performance, particularly at 4K where its 16 GB of GDDR6X memory is fully utilized. The 256-bit memory bus and 716.8 GB/s bandwidth provide ample throughput for high-resolution textures and complex scenery, which is essential for Microsoft Flight Simulator’s photorealistic terrain. The GPU’s base clock of 2205 MHz and boost clock of 2505 MHz are relatively high, and the 48.74 TFLOPS FP32 performance ensures that pixel shaders have enough compute power to render detailed clouds and water.

The RTX 4080’s 76 ray tracing cores and 304 tensor cores are not directly relevant to this game’s measured FPS, as the data doesn’t include ray tracing results. However, the GPU’s 112 ROPs and 304 TMUs contribute to the texture and pixel fill rates of 761.5 GTexel/s and 280.6 GPixel/s, respectively. These figures explain why the 4K Low result of 125 FPS is so high — the GPU has more than enough fill rate to handle 4K at low settings. The 16 GB VRAM is also a key factor, as it prevents texture swapping at 4K Ultra, which would otherwise cause stuttering.

Compared to its nearest rivals, the RTX 4080’s average benchmark score of 54,247 is just 0.1% lower than the RTX 4080 SUPER (54,209), meaning the SUPER offers no meaningful performance advantage in this game. The AMD Radeon Pro W5700X scores 1.1% higher, but it’s a workstation card with different drivers. The RX 6750 GRE 12 GB and Radeon 8060S score 2.6% and 2.7% higher respectively, but those are synthetic scores that don’t always translate to real-world gaming performance. The measured FPS data shows the RTX 4080 is well-suited for this sim, with 4K Medium at 97 FPS being a standout result.

The GPU’s 320 W TDP and suggested 700 W PSU are not directly measured, but they indicate the power envelope required for sustained performance. The triple-slot cooler and 310 mm length are physical attributes that don’t affect FPS but matter for system builders. The PCIe 4.0 x16 interface provides sufficient bandwidth for the 16 GB of VRAM, and the 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs support high-refresh 4K displays. The GPU’s production status is end-of-life, but its performance in this game remains strong, as evidenced by the 70 FPS at 4K Ultra.
