# CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 9 5900X is a 12-core, 24-thread desktop processor built on the Zen 3 architecture (Vermeer) using TSMC's 7 nm process. It operates with a base clock of 3.70 GHz and a boost clock of 4.80 GHz, and its configurable TDP is listed at 105 W. The processor supports DDR4 memory in a dual-channel configuration with a bandwidth of 51.2 GB/s, and it connects via PCIe Gen 4. This CPU sits at the 87th percentile among all tested CPUs, with an average benchmark score of 41,376 points.

In multi-threaded workloads, the 5900X delivers strong results: Cinebench R23 multi-core scores 16,262 points, while Geekbench multi-core reaches 14,118 points. Its single-thread performance is equally relevant for flight simulation, where many game logic and physics calculations run on fewer threads. The Cinebench R23 single-core score is 1,527, and 3DMark single-thread is 941. For the game-specific data, the CPU's ability to feed the GPU is visible in the measured FPS at 1080p, where the frame rates are highest across all settings.

Comparing to its nearest rivals, the Ryzen 9 5900X holds its ground. It is 0.3% ahead of the Intel Core Ultra 7 366H (avg score 41,263) and 0.4% ahead of both the Intel Core Ultra 7 356H (41,215) and the AMD Ryzen AI 5 PRO 440 (41,208). It trails the Intel Core i7-14650HX by only 0.5% (41,576). These margins are marginal, meaning the 5900X's performance tier is consistent with modern mid-to-high-end laptop and desktop chips, though none of these rivals are direct desktop equivalents.

For Microsoft Flight Simulator, the CPU's 12 cores and 24 threads provide ample headroom for background simulation tasks, but the single-thread performance is the more critical factor. The boost clock of 4.80 GHz, combined with a 3DMark 2-thread score of 1,852, indicates that the CPU can handle the game's typically light multi-threading demands. The data shows that at 1080p Low, the combo achieves 142 FPS, which is the highest measured figure in the entire dataset, suggesting that the CPU is not the primary bottleneck at lower resolutions and settings.

# GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 3070 Ti is built on the Ampere architecture (GA104 chip) using Samsung's 8 nm process. It features 8 GB of GDDR6X memory on a 256-bit bus, delivering a bandwidth of 608.3 GB/s. The GPU's base clock is 1575 MHz with a boost clock of 1770 MHz, and memory clocks run at 1188 MHz (19 Gbps effective). The card includes 6,144 shading units, 192 texture mapping units, 96 ROPs, 48 RT cores, and 192 tensor cores. Its FP32 performance is rated at 21.75 TFLOPS, and it draws a TDP of 290 W with a suggested PSU of 600 W. The RTX 3070 Ti ranks at the 75th percentile among all GPUs, with an average benchmark score of 29,945 points.

In synthetic benchmarks, the RTX 3070 Ti scores 23,356 in Passmark G3D and 91 in Passmark DirectX 12, with a Geekbench Vulkan score of 139,541 and OpenCL at 119,718. Its nearest rivals include the NVIDIA GeForce RTX 5070 Mobile (0.1% ahead, score 29,928), the AMD Radeon RX 6800 (0.5% ahead, score 30,095), the NVIDIA GeForce RTX 2080 Ti (0.5% behind, score 29,783), and the AMD Radeon RX 6700 (1.6% behind, score 30,433). Notably, the RTX 3070 Ti is essentially on par with these competitors, with deltas under 2%.

For Microsoft Flight Simulator, the GPU's 8 GB VRAM is a significant factor. The game's texture-heavy environments can stress VRAM capacity, particularly at higher resolutions and settings. The measured FPS data shows a clear pattern: at 4K Ultra, the combo drops to 47 FPS, while at 4K Low it reaches 85 FPS. This spread indicates that the GPU is heavily taxed at higher settings. The 608.3 GB/s memory bandwidth helps maintain throughput, but the 8 GB capacity may limit texture streaming in dense scenery areas.

The RTX 3070 Ti's clock speeds and memory configuration allow it to handle 1080p and 1440p with relative ease. At 1440p High, the combo produces 67 FPS, and at 1080p High, it reaches 83 FPS. The GPU's performance at 4K is more constrained, with only the Low preset exceeding 60 FPS. The data suggests that while the GPU is capable, it is the limiting component at higher resolutions and settings, as the CPU's headroom becomes less relevant once the GPU is saturated.

# Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

Examining the measured FPS across resolutions reveals how the workload shifts between CPU and GPU. At 1080p Low, the combo achieves 142 FPS, which drops to 115 FPS at 1440p Low (a 19% reduction) and further to 85 FPS at 4K Low (a 40% reduction from 1080p). This scaling indicates that even at Low settings, the GPU becomes more burdened as resolution increases, but the CPU still provides enough headroom to maintain reasonable frame rates.

At Medium settings, the pattern is similar but with a steeper drop. From 111 FPS at 1080p, the frame rate falls to 89 FPS at 1440p (a 20% drop) and then to 66 FPS at 4K (a 41% drop from 1080p). The fact that the percentage drop from 1080p to 4K is nearly identical between Low and Medium (40% vs 41%) suggests that the GPU is the primary scaling factor, as resolution changes impact pixel throughput more than CPU-bound logic.

At High settings, the scaling becomes more pronounced. The combo runs at 83 FPS at 1080p, drops to 67 FPS at 1440p (a 19% drop), and then to 49 FPS at 4K (a 41% drop from 1080p). Again, the 1080p-to-4K reduction hovers around 40%, reinforcing that the GPU is the dominant limiter. The Ultra preset shows the most severe scaling: 79 FPS at 1080p, 64 FPS at 1440p (a 19% drop), and 47 FPS at 4K (a 41% drop). The consistency of these percentage drops across settings points to a GPU-bound scenario at higher resolutions.

The data also shows that the gap between 1080p and 1440p is consistently around 19-20%, while the gap between 1440p and 4K is larger (about 26-27%). This indicates that the GPU's fill rate and memory bandwidth are more challenged when transitioning to 4K, where the pixel count quadruples. The CPU, with its strong single-thread performance, does not appear to bottleneck the system until frame rates are very high (e.g., 142 FPS at 1080p Low), which is still well within playable territory.

# Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS dataset provides a comprehensive view of this combo's performance across three resolutions and four settings presets.

At 1920x1080, the Low preset delivers an average of 142 FPS, the highest figure in the entire dataset. Medium settings yield 111 FPS, with a minimum of 94 FPS and a maximum of 127 FPS. High settings produce 83 FPS, while Ultra drops to 79 FPS. The spread from Low to Ultra is 63 FPS, showing that the GPU has significant headroom at this resolution, and even Ultra remains above 60 FPS.

At 2560x1440, the Low preset averages 115 FPS, a 19% reduction from 1080p. Medium settings average 89 FPS, with a minimum of 76 FPS and a maximum of 103 FPS. High settings deliver 67 FPS, and Ultra drops to 64 FPS. The gap between High and Ultra at 1440p is only 3 FPS, indicating that the Ultra preset's additional visual effects have diminishing returns on this GPU at this resolution.

At 3840x2160, the Low preset averages 85 FPS, which is still playable. Medium settings average 66 FPS, with a minimum of 56 FPS and a maximum of 76 FPS. High settings produce 49 FPS, and Ultra drops to 47 FPS. The gap between High and Ultra at 4K is only 2 FPS, showing that the GPU is severely limited at this resolution, and both presets fall below the 60 FPS threshold.

Notably, the Medium preset has min/max data for all three resolutions, while other presets only list average FPS. This suggests that the Medium preset is the only one where frame time variance was recorded in the dataset. The minimum FPS at 1080p Medium (94) is higher than the average FPS at 4K High (49), illustrating the performance cliff as resolution increases.

# Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends on the target resolution and desired frame rate.

For 1080p gaming, the Ultra preset is the best choice, delivering 79 FPS average. This provides the highest visual quality while maintaining frame rates well above 60 FPS. The gap between High (83 FPS) and Ultra (79 FPS) is only 4 FPS, so choosing Ultra costs minimal performance while offering the best visuals. If maximizing frame rate is the priority, the Low preset at 142 FPS is available, but this sacrifices significant visual fidelity.

For 1440p, the Medium preset offers the best balance, with an average of 89 FPS and a minimum of 76 FPS. This keeps frame rates smooth while providing better visuals than Low (115 FPS). The High preset (67 FPS) is still playable, but the Ultra preset (64 FPS) dips close to 60 FPS, and the visual improvement over High is negligible (3 FPS difference). Medium is recommended for its headroom above 60 FPS.

For 4K gaming, the Medium preset is the only viable option for a consistent experience, averaging 66 FPS with a minimum of 56 FPS. The Low preset (85 FPS) is smoother but lacks visual detail. High (49 FPS) and Ultra (47 FPS) both fall below 60 FPS, making them less desirable for gameplay. If the user prioritizes visual fidelity over frame rate, the High preset is slightly better than Ultra (by 2 FPS), but both are below the 60 FPS threshold.

Overall, the data indicates that this combo is best suited for 1080p and 1440p gaming, where it can handle high-to-ultra settings comfortably. At 4K, users must compromise on settings, with Medium being the recommended preset for playable performance. The measured FPS values show that the combo's sweet spot is 1440p Medium, which offers a good balance of performance and quality.
