Microsoft Flight Simulator

Microsoft Flight Simulator presents one of the most demanding workloads in the benchmark database, particularly for CPU-bound scenarios at lower resolutions. The AMD Ryzen 7 5800X and NVIDIA GeForce RTX 3080 Ti combination produces a distinctive scaling pattern that reveals the shifting bottleneck between processor and graphics card as resolution increases. This analysis examines the measured frame rates across three resolutions and four quality presets, interpreting what the data indicates about component utilization and overall system balance.

Resolution Scaling

The frame rate progression from 1080p to 4K clearly illustrates the transition from CPU-bound to GPU-bound performance. At 1080p with Low settings, the combo achieves 166.4 FPS, but this drops to 131.6 FPS at 1440p and further to 97.5 FPS at 4K. The percentage decline from 1080p to 4K at Low settings is approximately 41%, indicating that the CPU is heavily involved at the lowest resolution, with the GPU still having ample headroom. The 1080p Low result of 166.4 FPS suggests the Ryzen 7 5800X's 8 cores and 16 threads are being fully utilized, as the RTX 3080 Ti is capable of far higher frame rates in lighter scenes.

The scaling pattern changes dramatically when moving to Ultra settings. At 1080p Ultra, the system produces 89.3 FPS, while 1440p Ultra yields 73.9 FPS and 4K Ultra drops to 55.2 FPS. The decline from 1080p to 4K at Ultra is approximately 38%, which is similar in relative terms to the Low preset. However, the absolute frame rates are much lower, confirming that the GPU becomes the limiting factor at higher quality settings. The RTX 3080 Ti's 12 GB of GDDR6X memory and 912.4 GB/s bandwidth are being taxed heavily by the Ultra preset’s rendering demands.

The intermediate presets show the expected progression. At Medium settings, frame rates decline from 129.7 FPS at 1080p to 100.3 FPS at 1440p and 76.0 FPS at 4K. This represents a 41% drop from 1080p to 4K, nearly identical to the Low preset’s scaling. High settings follow a similar trajectory: 96.6 FPS at 1080p, 76.5 FPS at 1440p, and 56.6 FPS at 4K, a 41% reduction. The consistency of the percentage decline across presets suggests that the resolution scaling is primarily driven by GPU workload, while the CPU maintains sufficient performance to avoid becoming a bottleneck even at 1080p with lower settings.

How This Combo Ranks

Within the benchmark database, this combination of components ranks 426th out of 1795 tested combos for Microsoft Flight Simulator, placing it in the top 24% of all systems. This ranking reflects the balance between the Ryzen 7 5800X and RTX 3080 Ti, where the CPU’s strong single-thread performance and the GPU’s high compute capability combine to deliver competitive frame rates. The CPU’s benchmark percentile of 84 versus all CPUs indicates that the Ryzen 7 5800X is well above average, while the GPU’s percentile of 83 similarly positions the RTX 3080 Ti in the upper echelon of graphics cards.

The CPU’s average benchmark score of 27606 places it in close competition with several rivals. The AMD Ryzen 7 5800 is a near-exact match at 27535, a delta of just 0.3% in favor of the 5800X. The AMD Ryzen 5 8500GE and Intel Core i7-13700H both score slightly higher at 27708 and 27716 respectively, representing deltas of -0.4% against the 5800X. The Intel Core i5-12600KF leads this group with 27827, a 0.8% advantage. These tiny margins indicate that the 5800X is competitively positioned within its performance class, though not a standout leader.

For the GPU, the RTX 3080 Ti’s average benchmark score of 41224 is marginally lower than the NVIDIA GeForce RTX 3090’s 41441, a delta of -0.5%. The AMD Radeon Pro 5300 scores 41610, representing a 0.9% advantage, while the NVIDIA GeForce RTX 5070 reaches 41687 with a 1.1% lead. The NVIDIA Tesla M40 tops this group at 41897, a 1.6% margin. These comparisons show that the RTX 3080 Ti is slightly below the nearest competitors in raw compute benchmarks, yet its in-game performance remains strong due to architectural efficiencies in Flight Simulator’s rendering pipeline.

GPU Role

The RTX 3080 Ti’s memory subsystem is a critical factor in Flight Simulator’s performance. With 12 GB of GDDR6X memory on a 384-bit bus, the card delivers 912.4 GB/s of bandwidth, which is essential for streaming high-resolution terrain textures and detailed aircraft models. The 4K Ultra result of 55.2 FPS indicates that the GPU is near its limit, as the combination of high resolution and maximum quality settings demands both substantial memory capacity and bandwidth. The 8 nm process node and GA102 chip with 28,300 million transistors provide the raw compute necessary for the game’s complex shaders and lighting calculations.

The GPU’s clock speeds of 1365 MHz base and 1665 MHz boost are typical for this class of card, and the 34.10 TFLOPS FP32 performance handles the game’s geometry and pixel shading requirements. The 80 RT cores and 320 tensor cores are available for DirectX 12 Ultimate features, though Flight Simulator primarily relies on traditional rasterization. The 10240 shading units and 112 ROPs ensure that texture fill and pixel output keep pace with the game’s demands. The 186.5 GPixel/s pixel rate and 532.8 GTexel/s texture rate are sufficient to maintain the measured frame rates, but the 4K Ultra result shows that the card is operating near its architectural limits.

The GPU’s role becomes more pronounced at higher resolutions. At 1080p Low, the CPU is the primary constraint, as evidenced by the 166.4 FPS result that leaves GPU headroom. As resolution increases to 4K, the GPU workload grows quadratically, and the frame rates converge across presets. The difference between Low and Ultra at 1080p is 77.1 FPS, while at 4K the difference narrows to 42.3 FPS. This convergence demonstrates that the GPU is the dominant bottleneck at 4K, regardless of quality settings.

Measured FPS Breakdown

The measured frame rates reveal a consistent hierarchy across resolutions. At 1920x1080, the Low preset delivers 166.4 FPS, which is the highest result in the entire dataset. Medium produces 129.7 FPS, representing a 22% reduction from Low. High achieves 96.6 FPS, a 26% drop from Medium, while Ultra falls to 89.3 FPS, a 7.6% decline from High. The diminishing returns between High and Ultra suggest that the Ultra preset adds visual features with modest frame rate impact at 1080p, likely due to the CPU’s ability to feed the GPU adequately.

Moving to 2560x1440, the frame rates scale down proportionally. Low delivers 131.6 FPS, which is 79% of the 1080p Low result. Medium produces 100.3 FPS, 77% of its 1080p counterpart. High achieves 76.5 FPS, again 79% of the 1080p figure, and Ultra reaches 73.9 FPS, 83% of the 1080p Ultra result. The slight improvement in the Ultra preset’s scaling percentage suggests that the GPU’s memory bandwidth is more efficiently utilized at this resolution, reducing the relative performance penalty.

At 3840x2160, the frame rates drop to their lowest values. Low produces 97.5 FPS, which is 59% of the 1080p Low result. Medium delivers 76.0 FPS, 59% of 1080p Medium. High achieves 56.6 FPS, also 59% of the 1080p High figure, and Ultra bottoms out at 55.2 FPS, 62% of the 1080p Ultra result. The consistent 59% scaling factor across Low, Medium, and High presets indicates a uniform GPU bottleneck at 4K, while the Ultra preset’s slightly better scaling suggests that the game’s Ultra settings include features that are less resolution-dependent.

Settings Recommendations

For users prioritizing maximum visual fidelity at 4K, the Ultra preset’s 55.2 FPS average is just above the threshold for smooth flight simulation, where steady frame pacing matters more than raw frame rates. The High preset at 56.6 FPS offers nearly identical performance with a small reduction in visual effects, making it a practical choice for users who want to maintain a consistent experience without the minor frame rate penalty of Ultra. The data shows that the difference between High and Ultra at 4K is only 1.4 FPS, suggesting that Ultra’s additional features have minimal impact at this resolution.

At 1440p, the High preset delivers 76.5 FPS, which provides a comfortable margin above the 60 FPS target for most displays. The Ultra preset at 73.9 FPS is also viable, offering the highest quality settings with only a 3.4% reduction in frame rate compared to High. For users with high refresh rate monitors, the Medium preset at 100.3 FPS provides a substantial boost in smoothness while still maintaining respectable visual quality. The Low preset at 131.6 FPS is the only option that fully utilizes 1440p high refresh displays, though it sacrifices significant visual fidelity.

The 1080p resolution offers the most flexibility. The High preset at 96.6 FPS provides an excellent balance of visual quality and performance, suitable for most gaming monitors. Ultra at 89.3 FPS is nearly as smooth and is recommended for users who prioritize image quality above all else. For competitive or fast-paced scenarios, the Medium preset at 129.7 FPS offers a significant frame rate advantage with modest visual compromises. The Low preset at 166.4 FPS is the best choice for maximum smoothness, though it substantially reduces the visual experience that Flight Simulator is known for. Considering the entire dataset, the High preset at 1440p provides the best overall experience, delivering 76.5 FPS with strong visual quality and adequate performance for immersive flight simulation.
