Microsoft Flight Simulator

Resolution Scaling

The measured frame rates for Microsoft Flight Simulator show a predictable but uneven scaling pattern as resolution climbs. At 1080p with Low settings, the combination of the AMD Ryzen 7 7800X3D and NVIDIA GeForce RTX 5080 delivers 200.1 FPS. Dropping to 1440p Low reduces that to 177.1 FPS, a modest 11.5% decline, while 4K Low still holds 127.6 FPS. This relatively shallow curve at Low settings suggests that the CPU retains significant headroom even at higher pixel counts, and the GPU is not yet saturated.

The picture changes dramatically when settings are raised. At Ultra, the 1080p result is 124.5 FPS, the 1440p result is 99.1 FPS, and the 4K result falls to 73.3 FPS. The gap between Low and Ultra at 1080p is 75.6 FPS, but at 4K that gap shrinks to 54.3 FPS. This compression indicates that at 4K Ultra, the RTX 5080 becomes the primary limiting component, with the flight simulator's heavy draw calls and complex scenery pushing GPU throughput to its ceiling. The CPU, with its 96 MB of shared L3 cache and 16 threads, is able to feed frames faster than the GPU can render them at the highest resolution.

Intermediate settings reinforce this interpretation. Medium at 1080p yields 174.6 FPS, which drops to 139.9 FPS at 1440p and 98.4 FPS at 4K. High settings follow a similar trajectory: 128.8 FPS at 1080p, 105.3 FPS at 1440p, and 79 FPS at 4K. The scaling from 1440p to 4K at High represents a 25% performance loss, whereas the scaling from 1080p to 1440p at the same preset is only 18.2%. This accelerating degradation with resolution is the classic signature of a GPU-bound workload at the top end.

What stands out is how well the 7800X3D holds frame rates at lower resolutions. The delta between 1080p and 1440p at Low is just 23 FPS, and the delta between 1440p and 4K at Low is 49.5 FPS. For a flight simulator that must process terrain streaming, weather systems, and cockpit instrumentation simultaneously, the 8-core Zen 4 processor with its 3D V-Cache appears to be a strong match. The data suggests that users targeting 4K Ultra should expect roughly 73 FPS, while those willing to step down to High gain about 6 FPS. Medium provides a more substantial jump to 98.4 FPS, which is a 34.2% improvement over Ultra at the same resolution.

GPU Role

The NVIDIA GeForce RTX 5080 brings 16 GB of GDDR7 memory across a 256-bit bus, yielding a memory bandwidth of 960.0 GB/s. In Microsoft Flight Simulator, where high-resolution textures for aircraft, airports, and photogrammetry cities can consume VRAM rapidly, this capacity is substantial. The measured results show that even at 4K Ultra, the combination maintains playable frame rates, which indicates that the memory subsystem is not being overwhelmed by texture data. The 30 Gbps effective memory clock and 1875 MHz memory clock are markers of a high-bandwidth design that suits this simulator's large, streaming assets.

The GPU's boost clock of 2617 MHz and base clock of 2295 MHz position it as a high-frequency Blackwell part. With 10752 shading units and 112 ROPs, the RTX 5080 has ample raw compute for pixel-heavy workloads. The pixel rate of 293.1 GPixel/s and texture rate of 879.3 GTexel/s help explain why the card maintains 73.3 FPS at 4K Ultra, a demanding scenario for any GPU. The 84 RT cores and 336 tensor cores are present, though Microsoft Flight Simulator's current rendering path does not appear to leverage ray tracing heavily in these measured settings.

The FP32 throughput of 56.28 TFLOPS (1:1 ratio with FP16) provides a measure of the card's shader compute potential. In practice, the frame rates at 4K suggest that the GPU is the bottleneck at Ultra settings, as the CPU is unlikely to fall below 100 FPS in this title given its 1080p Low result of 200.1 FPS. The RTX 5080's nearest rivals in the database include the Intel Arc A570M with a 1.6% higher average benchmark score, and the Intel Arc Pro A60 with a 1.9% lower score. These deltas are small in synthetic benchmarks, but in-game the RTX 5080's 16 GB frame buffer and 960.0 GB/s bandwidth would be decisive for high-resolution flight simulation.

The GPU's 360 W TDP and dual-slot design indicate a power-hungry part, but the measured FPS data does not reveal thermal throttling. The card sustains its performance across all four settings at each resolution. At 1080p, the difference between Low and Ultra is 75.6 FPS, which shows that the GPU has enough headroom to render at high settings even when CPU-bound. At 4K, the difference narrows to 54.3 FPS, confirming that the GPU's workload is the limiting factor. Users with high-refresh displays at 1440p will find that High settings deliver 105.3 FPS, which is comfortably above the 100 FPS threshold for smooth flight simulation.

How This Combo Ranks

The AMD Ryzen 7 7800X3D with the NVIDIA GeForce RTX 5080 ranks 72nd out of 1795 tested combinations for Microsoft Flight Simulator. This places the pairing in the top 4% of all configurations in the database, a strong result for a flight simulator that is notoriously demanding on both CPU and GPU. The rank reflects the balanced nature of this pairing: the 7800X3D's strong single-thread and multi-thread performance (3dmark single-thread score of 959, cinebench r23 multicore score of 29149) complements the RTX 5080's high-end rasterization throughput.

The CPU's percentile ranking of 87 against all processors indicates that it outperforms the vast majority of CPUs in general benchmarks. Its average benchmark score of 31580 is nearly identical to the Intel Core i7-12700F, which scores 31543 with a 0.1% delta. The AMD Ryzen 9 5980HX sits 0.3% behind, and the AMD Ryzen 7 8700G trails by 0.6%. These tight deltas suggest that the 7800X3D is not the limiting factor in this game; its 3D V-Cache provides substantial benefit for flight simulation's complex scene graphs and terrain algorithms.

Its average benchmark score of 59188 is 1.6% higher than the Intel Arc A570M's 58239, and 2.5% higher than the Intel Arc A580's 57756. The AMD Radeon Pro W5500X scores 2.6% lower. These rivals are not typical gaming GPUs, which underscores that the RTX 5080 sits in a performance tier where direct competition is sparse. The combination's 72nd overall rank out of 1795 combos means that only 71 other pairings deliver higher measured FPS in this title, and those would likely involve even more powerful GPUs or CPUs with higher clock speeds.

Given that the data shows 4K Ultra performance of 73.3 FPS, the combo is well-suited to high-refresh 1440p gaming and capable 4K play. At 1440p High, the 105.3 FPS result is strong for a simulator that often struggles to reach triple digits. The rank of 72 suggests that while this is not the absolute fastest combo for Microsoft Flight Simulator, it offers a near-top-tier experience without requiring exotic cooling or power delivery. The 120 W TDP of the CPU and 360 W TDP of the GPU indicate a system that is manageable with a quality power supply, though no specific PSU recommendation is implied by the data.

Settings Recommendations

The measured data provides clear guidance for optimizing the experience with this hardware. At 4K, Ultra settings yield 73.3 FPS, which is playable for a flight simulator but leaves little headroom for complex scenery or weather. Dropping to High at 4K raises the average to 79 FPS, a modest 7.8% improvement that may not be worth the visual downgrade. Medium at 4K delivers 98.4 FPS, which is a 34.2% improvement over Ultra and likely provides a more consistent experience during dense urban flyovers or storm systems. Low at 4K reaches 127.6 FPS, but this sacrifices too much visual fidelity for a simulator where terrain readability matters.

For 1440p, High settings at 105.3 FPS offer the best balance of fidelity and smoothness. Ultra at 99.1 FPS is close, but High's 6.2% advantage in frame rate may be preferable for maintaining 100+ FPS on high-refresh monitors. Medium at 139.9 FPS and Low at 177.1 FPS are available for users who prioritize frame rate above all else, but the visual complexity of flight simulation benefits from higher presets. At 1080p, High delivers 128.8 FPS and Ultra delivers 124.5 FPS, a negligible difference that suggests Ultra is viable for users who want maximum quality without sacrificing performance.

The data indicates that the sweet spot for this combo is 1440p High, where the 105.3 FPS average provides smooth panning and responsive controls. For 4K users, Medium at 98.4 FPS is the recommended preset, as it maintains near-100 FPS while retaining enough visual detail for situational awareness. Ultra at 4K is technically playable at 73.3 FPS, but the simulator's tendency to load heavy scenery on approach and departure could cause frame dips below 60 FPS in demanding areas. The 7800X3D's strong cache architecture and the RTX 5080's 16 GB VRAM ensure that even at Medium settings, texture detail remains high, and the 960.0 GB/s memory bandwidth prevents stuttering from asset streaming.

Ultimately, the measured rows suggest that users should prioritize either 1440p High for the best overall experience or 4K Medium for maximum resolution without sacrificing frame rate. The combination's rank of 72 out of 1795 confirms that this pairing is capable of delivering an excellent flight simulation experience, and the settings recommendations above are derived directly from the average FPS figures for each preset and resolution.
