Microsoft Flight Simulator

The data shows that the Intel Core i5-10400F and AMD Radeon RX 7700 XT combination delivers a playable, though not overwhelmingly smooth, experience in Microsoft Flight Simulator, with performance scaling that clearly identifies the GPU as the primary bottleneck at higher resolutions. The measured frame rates indicate that while the CPU is capable of feeding the GPU at 1080p, the demands of 4K resolution push the graphics card to its limits, resulting in a significant performance drop.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a classic GPU-bound scenario. At 1080p with High settings, the combo produces an average of 81 FPS. Moving to 1440p drops this to 65 FPS, a reduction of 16 FPS. The jump to 4K is more punishing, with the average falling to 48 FPS. This pattern shows that the RX 7700 XT’s rendering workload scales heavily with pixel count, which is expected for a flight simulator with dense terrain and weather effects.

The scaling behavior is even more pronounced at lower settings. At Low settings, the average frame rate goes from 134 FPS at 1080p to 112 FPS at 1440p, and then down to 82 FPS at 4K. The 52 FPS difference between 1080p and 4K at Low settings is a 39% drop, indicating that even when the graphics load is reduced, the GPU still struggles to maintain high output at 4K. This suggests that the RX 7700 XT is the limiting factor at this resolution, as reducing settings does not fully compensate for the increased pixel count.

At Medium settings, the frame rate drops from 108 FPS at 1080p to 87 FPS at 1440p and then to 64 FPS at 4K. The gap between 1440p and 4K is 23 FPS, which is larger than the 21 FPS gap between 1080p and 1440p. This non-linear decline points to the GPU hitting a hard computational ceiling as resolution increases, rather than a CPU limitation. The Ultra settings follow the same trend, with averages of 77 FPS at 1080p, 62 FPS at 1440p, and 46 FPS at 4K.

The data suggests that 1080p is the sweet spot for this combination if aiming for high refresh rates, while 1440p remains viable for smooth gameplay. At 4K, the average frame rates fall below the 60 FPS threshold for all settings except Low, meaning users will have to accept lower visual fidelity to maintain fluid motion. The limiting component at 4K is clearly the GPU, as the CPU’s performance does not degrade with resolution.

GPU Role

The AMD Radeon RX 7700 XT, with its 12 GB of GDDR6 memory on a 192-bit bus, provides a memory bandwidth of 432.0 GB/s. This is a substantial amount of bandwidth, which is crucial for a game like Microsoft Flight Simulator that streams large amounts of terrain and texture data. The GPU’s boost clock of 2544 MHz and game clock of 2171 MHz indicate a high operating frequency, which helps with the raw compute required for rendering complex scenes.

In the measured results, the GPU’s influence is most apparent in the difference between Low and High settings at the same resolution. At 4K, the average frame rate increases from 48 FPS on High to 82 FPS on Low, a 34 FPS gain. This shows that the GPU has headroom when the shading and texture work is reduced. The GPU’s 35.17 TFLOPS of FP32 compute power is sufficient for high-detail rendering, but the 4K resolution demands more than it can deliver consistently.

The GPU’s 96 ROPs and 216 TMUs handle pixel and texture processing, and the 244.2 GPixel/s pixel rate is a key factor in the 4K performance. The benchmark scores for the GPU show a Passmark G3D score of 22547, which places it in the 67th percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce RTX 2080 with a score of 22895 and a deltaPct of -1.5%, indicating the RX 7700 XT is slightly slower in synthetic tests. However, the in-game results show that the GPU is still the decisive component for frame rate at higher resolutions.

The GPU’s 12 GB memory capacity is not a limiting factor in these measurements, as the game does not appear to exceed this capacity at the tested settings. The 432.0 GB/s bandwidth is more relevant, and the data shows that the GPU’s memory subsystem is not causing a bottleneck until the 4K Ultra settings, where the average frame rate drops to 46 FPS. This is likely due to the increased memory pressure from higher-resolution textures and draw distances.

CPU Role

The Intel Core i5-10400F provides 6 cores and 12 threads, with a base clock of 2.90 GHz and a boost clock of 4.30 GHz. This Comet Lake processor has a 12 MB shared L3 cache and supports dual-channel DDR4 memory with a bandwidth of 42.7 GB/s. In synthetic benchmarks, the CPU scores 10283 in Cinebench R23 multi-core and 1451 in single-core, which reflects a solid mid-range performance level for a desktop processor.

In Microsoft Flight Simulator, the CPU’s role is to manage the simulation logic, physics, and AI traffic, while the GPU handles the visual rendering. The measured frame rates show that the CPU is not the limiting factor at 1080p, as the average frame rate scales with settings. For instance, at 1080p, the frame rate goes from 134 FPS on Low to 77 FPS on Ultra, indicating that the GPU is the bottleneck even at the lowest settings. If the CPU were the constraint, the frame rate would remain similar regardless of settings.

The CPU’s boost clock of 4.30 GHz is sufficient to keep up with the GPU’s output at 1080p. However, at 4K, the CPU’s workload does not increase significantly, as the simulation logic is resolution-independent. The data confirms this, as the frame rate drop from 1080p to 4K is consistent across all settings, with the CPU maintaining a stable performance level. The CPU’s 3DMark single-thread score of 688 and 2-thread score of 1350 suggest that the game’s main thread is well-handled, but the multicore scores (4748 for 16 threads) show that the processor can handle the multi-threaded simulation tasks.

The CPU’s percentile rank of 68 vs all CPUs indicates it is above average, and its nearest rivals include the Intel Xeon 6756E with a deltaPct of 0.2% and the AMD EPYC 7552 with a deltaPct of 0.5%. This shows that the i5-10400F is competitive with much higher-end server processors in synthetic tests, but in this game, it does not contribute to frame rate limitations. The benchmark results indicate that the CPU is a capable partner for the RX 7700 XT, but it does not drive the performance differences seen across resolutions.
