FAQ

Q: What is the best resolution for this combo in Microsoft Flight Simulator?

A: The data shows 1440p is the sweet spot. At 2560x1440 High settings, the average FPS is 60.6, which is smooth for a flight sim. Dropping to 1080p High yields 81 FPS, while 4K High drops to 46.6 FPS.

Q: How does the RTX 3070 handle Ultra settings at 1440p?

A: At 2560x1440 Ultra, the measured average is exactly 60.0 FPS. This is the boundary where the GPU starts to become the limiting factor, as the frame rate aligns with typical 60 Hz monitor refresh rates.

Q: Is the Ryzen 7 5800X3D strong enough to avoid bottlenecking the RTX 3070?

A: Yes. The CPU has 8 cores and 16 threads with a boost clock of 4.50 GHz. Its 3DMark single-thread score of 884 and 16-thread score of 7299 indicate it can feed the GPU effectively, especially at lower resolutions where CPU load is proportionally higher.

Q: What is the performance difference between Low and Ultra at 1080p?

A: At 1920x1080, the jump from Low (135.8 FPS) to Ultra (73.6 FPS) represents a 45.8% drop in average FPS. This shows the RTX 3070 can deliver very high frame rates at lower settings but is heavily taxed by the simulation's Ultra preset.

Q: How does the combo rank compared to other tested systems?

A: The combo ranks 803rd out of 1795 tested combinations. This places it in the 55th percentile of all tested combos, meaning about 45% of systems perform better, which is respectable given the demanding nature of this flight simulator.

Q: Does the 8 GB VRAM cause issues at 4K?

A: The data suggests it does. At 3840x2160, the average FPS drops to 46.6 on High and 43.8 on Ultra. The 8 GB GDDR6 memory with 448.0 GB/s bandwidth is likely saturated at this resolution, limiting performance compared to the 1440p results.

How This Combo Ranks

The AMD Ryzen 7 5800X3D + NVIDIA GeForce RTX 3070 combination ranks 803rd out of 1795 tested combos in Microsoft Flight Simulator.

In game-specific terms, the combo's 803rd rank out of 1795 means it is firmly in the middle of the pack. The measured FPS data shows it can handle 1080p and 1440p with ease, but 4K Ultra presents a challenge where the system falls below the 60 FPS threshold. This ranking reflects a balanced system where neither component is severely mismatched, but the GPU becomes the limiting factor at maximum settings.

GPU Role

The NVIDIA GeForce RTX 3070 is built on the Ampere architecture with 5888 shading units, 184 texture mapping units, and 96 raster output units. Its base clock is 1500 MHz with a boost clock of 1725 MHz, and it features 46 ray tracing cores and 184 tensor cores. The GPU has 8 GB of GDDR6 memory on a 256-bit bus, delivering 448.0 GB/s of bandwidth.

In Microsoft Flight Simulator, the GPU's role is most evident at higher resolutions and settings. At 1080p Low, the measured 135.8 FPS shows the GPU is not the limiting factor. However, as resolution increases to 1440p and 4K, the average FPS drops significantly. At 4K High, the system achieves 46.6 FPS, while at 4K Ultra it falls to 43.8 FPS. This pattern indicates that the RTX 3070's 8 GB VRAM is a bottleneck at 4K, as the flight simulator requires large textures and complex scenery data.

The GPU's PassMark G3D score of 22214 and DirectX 12 score of 85 reflect its overall capability. Its 20.31 TFLOPS FP32 performance is substantial, but the 8 GB memory capacity is the key constraint in this game. At 1440p, the GPU performs admirably, delivering 60.6 FPS on High and exactly 60.0 FPS on Ultra, suggesting the VRAM is sufficient at this resolution but the GPU compute is nearing its limits.

Measured FPS Breakdown

The measured FPS data reveals a consistent pattern across all resolutions. At 1920x1080, the average FPS ranges from 135.8 on Low to 73.6 on Ultra, with Medium at 108.3 and High at 81.0. These numbers show that at 1080p, the combo can easily exceed 60 FPS even at maximum settings, making it a very playable experience.

Moving to 2560x1440, the average FPS drops to 108.4 on Low, 85.0 on Medium, 60.6 on High, and 60.0 on Ultra. This is a significant reduction from 1080p, but the system still maintains playable frame rates at all settings. The 1440p Ultra result of 60.0 FPS is exactly at the 60 FPS threshold, which is acceptable for a flight simulator where smooth panning is less critical than in fast-paced action games.

At 3840x2160, the performance drops more sharply. Low settings yield 80.3 FPS, Medium produces 63.0 FPS, High falls to 46.6 FPS, and Ultra bottoms out at 43.8 FPS. The jump from Medium to High at 4K represents a 25.9% drop in frame rate, highlighting the GPU's struggle with the higher quality presets at this resolution. The 4K Ultra result of 43.8 FPS is below the 60 FPS target, but may still be acceptable for some users given the game's slower pacing.

Resolution Scaling

The resolution scaling analysis reveals how the system's performance degrades as pixel count increases. From 1080p to 1440p, the average FPS drops by approximately 25-28% across settings. For example, High settings fall from 81.0 FPS at 1080p to 60.6 FPS at 1440p, a 25.2% reduction. This indicates that the GPU is handling the increased pixel load reasonably well, but the scaling is not linear.

From 1440p to 4K, the drop is more severe. High settings fall from 60.6 FPS to 46.6 FPS, a 23.1% decrease, while Ultra drops from 60.0 FPS to 43.8 FPS, a 27% decrease. The total scaling from 1080p to 4K on High settings is from 81.0 FPS to 46.6 FPS, a 42.5% reduction. This substantial drop suggests that the RTX 3070 is becoming heavily constrained at 4K, likely due to both the increased pixel count and the 8 GB VRAM limit.

The scaling pattern indicates that the CPU is not the primary bottleneck in this game. If the CPU were the limiting factor, the frame rates would remain similar across resolutions. Instead, the consistent drop in FPS as resolution increases points to the GPU as the limiting component, particularly at 4K where the memory bandwidth and capacity are stretched.

CPU Role

The AMD Ryzen 7 5800X3D is a Zen 3 architecture processor on the Vermeer codename, built on a 7 nm process. It has 8 cores and 16 threads, with a base clock of 3.40 GHz and a boost clock of 4.50 GHz. The defining feature is its 96 MB shared L3 cache, which is exceptionally large and provides a significant advantage in games that benefit from high cache capacity.

In Microsoft Flight Simulator, the CPU's role is critical due to the game's complex simulation logic and terrain rendering. The 5800X3D's benchmark scores reflect its strength: Cinebench R23 multicore score of 24063 and single-core score of 3397, with a Geekbench multicore score of 11061 and single-core score of 2116. These numbers indicate the CPU can handle both multi-threaded simulation tasks and single-threaded game logic.

The CPU's nearest rivals include the AMD EPYC 8024P (delta 0.1%) and Intel Core i9-11900K (delta 0.1%), showing it is competitive with other high-end processors. Its passmark multithread score of 28309 and single-thread score of 3234 further confirm its capability.

The data suggests the 5800X3D is well-matched to the RTX 3070 in this game. At 1080p Low, the system achieves 135.8 FPS, which would require the CPU to feed frames quickly. The 5800X3D's high single-thread performance and large cache help maintain consistent frame delivery. However, at 4K Ultra, the CPU's advantage is less relevant as the GPU becomes the bottleneck, evidenced by the sharp FPS drops at higher resolutions.
