Resolution Scaling

The measured FPS data for Microsoft Flight Simulator with the AMD Ryzen 5 5600 and NVIDIA GeForce RTX 3080 Ti reveals a predictable yet informative scaling pattern as resolution increases. At 1920x1080 with Low settings, the combo delivers 164.6 FPS, which drops to 133 FPS at 2560x1440, and further to 93.4 FPS at 3840x2160. This represents a 43% reduction from 1080p to 4K at Low settings, indicating that even at the lowest graphical preset, the GPU is still the primary scaling factor. The RTX 3080 Ti's 12 GB of GDDR6X memory and 912.4 GB/s bandwidth become increasingly relevant at higher resolutions, where the frame buffer demands grow substantially.

At Medium settings, the scaling is similar but slightly steeper: 126.7 FPS at 1080p, 104.7 FPS at 1440p, and 76.8 FPS at 4K. The drop from 1440p to 4K is 26.6%, while the drop from 1080p to 1440p is 17.4%. This non-linear scaling suggests that the GPU's memory bandwidth and shading throughput are being taxed more heavily as pixel count increases, with the 4K resolution exposing the limits of the 34.10 TFLOPS FP32 compute capability. The High preset shows a similar pattern: 96.6 FPS at 1080p, 77.9 FPS at 1440p, and 57.8 FPS at 4K, with the 4K figure approaching the 54.2 FPS seen at Ultra.

The Ultra preset at 4K produces 54.2 FPS, which is the lowest measured value across all configurations. The gap between High and Ultra at 4K is only 3.6 FPS, suggesting that the Ultra preset's additional visual features—likely related to terrain detail and object density—are heavily GPU-bound at this resolution. The data indicates that the RTX 3080 Ti is the limiting component across all resolutions and settings, as the CPU's role becomes less prominent when the GPU is saturated. The 1080p to 1440p scaling at Ultra (91.7 to 73.3 FPS, a 20% drop) is shallower than the 1440p to 4K scaling (73.3 to 54.2 FPS, a 26% drop), reinforcing that the GPU's pixel throughput and memory bandwidth are the bottlenecks at higher resolutions.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant component in this pairing for Microsoft Flight Simulator. Its 12 GB of GDDR6X memory on a 384-bit bus provides 912.4 GB/s of bandwidth, which is critical for streaming the high-resolution textures and terrain data that flight simulators demand. The GPU's 10240 shading units and 80 RT cores are fully engaged during gameplay, as evidenced by the measurable FPS differences between presets. At 1080p Low, the card produces 164.6 FPS, but this drops to 91.7 FPS at Ultra, a 44.3% reduction that demonstrates the compute load of higher-quality shadows, reflections, and lighting effects.

The boost clock of 1665 MHz (base 1365 MHz) allows the GA102 chip to maintain high throughput across the 320 TMUs and 112 ROPs. The texture rate of 532.8 GTexel/s and pixel rate of 186.5 GPixel/s are directly relevant to flight simulator's vast draw distances and detailed ground textures. The GPU's 34.10 TFLOPS FP32 performance is adequate for 1440p gaming at high settings, where the combo achieves 77.9 FPS, but falls short of 60 FPS at 4K Ultra with 54.2 FPS. The benchmark results place this GPU in the 83rd percentile among all GPUs, with an average benchmark score of 41224, putting it just 0.5% behind the RTX 3090 and 1.1% ahead of the RTX 5070 in aggregate scores.

The 350 W TDP and 750 W suggested PSU reflect the card's power appetite, but the performance data shows that the RTX 3080 Ti is well-suited for high-refresh 1440p play in this title. At 1440p Medium, the 104.7 FPS result indicates headroom for competitive or smooth exploration gameplay, while 4K High at 57.8 FPS is borderline for 60 Hz displays. The GPU's DirectX 12 Ultimate support (12_2) and Vulkan 1.4 API compatibility ensure modern rendering features are available, though the measured results suggest the game's engine does not fully utilize ray tracing capabilities in these presets.

CPU Role

The AMD Ryzen 5 5600 provides six cores and twelve threads, with a base clock of 3.50 GHz and boost clock of 4.40 GHz. In Microsoft Flight Simulator, a title known for complex physics and AI traffic simulation, the CPU's single-thread performance is crucial. The 3DMark single-thread score of 882 and Cinebench R23 single-core score of 2584 indicate robust per-core performance, which is reflected in the FPS data. At 1080p Low, the combo reaches 164.6 FPS, which is likely near the CPU's practical limit for this game, as the GPU is not fully stressed at this resolution and preset.

The CPU's 32 MB shared L3 cache and Zen 3 architecture provide low-latency access to frequently used data, which helps maintain consistent frame pacing during flights over complex terrain. The 3DMark 8-thread score of 4798 and max-thread score of 5659 show that the CPU scales reasonably with additional threads, though the game's primary simulation thread remains the bottleneck. The Cinebench R20 multicore score of 7689 and R15 multicore score of 1845 indicate solid multi-threaded capability for background tasks like scenery loading. The CPU sits in the 79th percentile among all CPUs with an average benchmark score of 21765, placing it 0.6% ahead of the Intel Xeon D-1746TER and 0.9% behind the Intel Core i7-11700F.

The data shows that at 1440p and 4K, the CPU's influence diminishes as the GPU becomes the limiting factor. At 4K Ultra, the FPS drops to 54.2, which is 67% lower than the 1080p Low result, indicating that the GPU is fully saturated while the CPU still has headroom. However, at 1080p, the CPU's performance ceiling is apparent: the gap between Low (164.6 FPS) and Ultra (91.7 FPS) is 44.3%, but the gap between 1080p and 1440p at Low (164.6 to 133 FPS) is 19.2%, suggesting that the CPU's single-thread performance limits maximum frame rates when the GPU is not the bottleneck. The CPU's 65 W TDP and DDR4 dual-channel memory support (51.2 GB/s bandwidth) are adequate for this workload, though the game's engine appears to favor higher single-core clocks over additional cores.
