Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title, and the pairing of the Intel Core i5-10400F with the AMD Radeon RX 7600 produces a set of results that clearly illustrate where the bottlenecks lie. The data shows a system that is capable of smooth flight at lower presets but struggles to maintain high frame rates at maximum visual fidelity. This analysis breaks down the measured performance to help you understand what to expect from this specific configuration.

Resolution Scaling

The measured FPS data reveals a steep performance drop as resolution increases, which is typical for a GPU-bound scenario at higher settings. At 1080p with Low settings, the system achieves 101 FPS average. Moving to 1440p Low drops that to 81 FPS, and at 4K Low, the average falls to 60 FPS. This scaling pattern—a roughly 20% reduction from 1080p to 1440p and another 25% reduction from 1440p to 4K—indicates that even at the lowest quality preset, the AMD Radeon RX 7600 is the primary limiter as pixel count rises.

The picture changes dramatically when looking at the Ultra preset. At 1080p Ultra, the average FPS is 56. At 1440p Ultra, it drops to 45 FPS, and at 4K Ultra, it plummets to 33 FPS. The gap between Low and Ultra at 4K is substantial (60 FPS vs 33 FPS), showing that the GPU's workload increases exponentially with both resolution and graphical fidelity. The data suggests that the RX 7600's 8 GB of VRAM and its compute capabilities are stretched thin at 4K Ultra, making that combination impractical for smooth play.

Interestingly, the scaling from 1080p to 1440p on the Medium preset shows a smaller relative drop (79 FPS to 63 FPS) compared to the Low preset's drop (101 FPS to 81 FPS). This suggests that at Medium settings, the system is balancing CPU and GPU load more evenly at 1080p, but the GPU quickly becomes the limiting factor as resolution increases. The takeaway is clear: for this game, the RX 7600 is the component that dictates performance scaling, and the i5-10400F has enough headroom to keep up until the GPU is fully saturated at 4K.

FAQ

GPU Role

The AMD Radeon RX 7600 is the star of this show, and its specifications explain the measured results well. It features 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. This memory configuration is adequate for 1080p and 1440p gaming but becomes a limiting factor at 4K Ultra, where the game's large textures can exceed the VRAM capacity, leading to the significant frame rate drop to 33 FPS.

Clock speeds are relatively high, with a base clock of 1720 MHz and a boost clock of 2655 MHz. The GPU's game clock is listed at 2250 MHz, which is the typical speed expected during gaming loads. These clocks, combined with 2048 shading units and 32 ray accelerators, allow the card to achieve a texture rate of 339.8 GTexel/s and a pixel rate of 169.9 GPixel/s. These numbers translate to strong rasterization performance, which is why the card performs well at lower settings where the CPU is not a factor.

The GPU's benchmark scores support its mid-range positioning. It scores 16634 in Passmark G3D, which places it in the 57th percentile of all GPUs. Its nearest rival, the NVIDIA GeForce RTX 3050 OEM, scores 15199, meaning the RX 7600 is about 0.2% faster in this specific metric. The data shows that the GPU is well-suited for 1080p High settings (59 FPS average) and 1440p Medium (63 FPS average), but it lacks the raw compute power and memory bandwidth to handle 4K Ultra without significant compromises.

Measured FPS Breakdown

The measured data provides a clear matrix of performance across three resolutions and four settings presets. Starting at 1080p, the system shows strong performance. Low settings produce an average of 101 FPS, Medium produces 79 FPS with a minimum of 67 FPS, High produces 59 FPS, and Ultra produces 56 FPS. This progression shows that the jump from High to Ultra is small (3 FPS), suggesting that the Ultra preset's additional effects are not heavily taxing at 1080p.

At 1440p, the averages are 81 FPS for Low, 63 FPS for Medium (with a minimum of 54 FPS), 48 FPS for High, and 45 FPS for Ultra. The delta between High and Ultra remains small (3 FPS), but the overall performance has dropped by roughly 20% compared to 1080p across all settings. The Medium preset's minimum of 54 FPS indicates that there can be noticeable dips in complex scenes, but it remains playable.

At 4K, the results show a hard limit. Low settings average 60 FPS, which is exactly at the threshold for smooth gameplay. Medium drops to 47 FPS with a minimum of 40 FPS, High drops to 35 FPS, and Ultra drops to 33 FPS. The data shows that 4K is only practical at Low settings for this combo. The gap between Medium and High (12 FPS) is larger than the gap between High and Ultra (2 FPS), indicating diminishing returns and a heavy GPU load at 4K.

Settings Recommendations

For the best experience, the data points to the Medium preset at 1080p as the sweet spot. It delivers an average of 79 FPS with a minimum of 67 FPS, ensuring smooth performance even during demanding flight scenarios. The 67 FPS minimum is important for flight simulators, where stutters can be disorienting. This preset offers a significant improvement over High (59 FPS average) while maintaining a high frame rate.

If you have a 1440p monitor, Medium is again the recommended preset, yielding an average of 63 FPS and a minimum of 54 FPS. While the minimum is lower than at 1080p, it remains acceptable for a game of this genre. Pushing to High at 1440p drops the average to 48 FPS, which may be tolerable but risks noticeable slowdowns in dense areas.

For 4K users, the only viable option is Low settings, which average 60 FPS. It is important to note that this is a hard ceiling; any increase in settings will result in averages below 50 FPS. The Ultra preset is not recommended at any resolution due to the marginal visual improvement over High (3 FPS difference) and the significant performance cost at 4K (33 FPS average).

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor based on the Comet Lake architecture. It has a base clock of 2.90 GHz and a boost clock of 4.30 GHz. These specifications are sufficient for gaming, as evidenced by the high frame rates at 1080p Low (101 FPS average). The CPU's passmark multithread score is 12115, and its single-thread score is 2541, which places it in the 68th percentile of all CPUs.

The CPU's benchmarks show a balanced profile. It scores 10283 in Cinebench R23 multicore and 1451 in single-core, indicating solid multi-threaded performance that can handle the game's background simulation tasks. Its nearest rival, the Intel Core 7 160UL, has an average score of 14232, which is 0.3% higher than the i5-10400F's 14185 average. This suggests the CPU is competitive with other mid-range options.

In this specific game, the CPU does not appear to be the bottleneck at higher resolutions. The consistent FPS drop from 1080p to 4K across all settings indicates a GPU limitation. However, at 1080p Low, the system reaches 101 FPS, which shows the CPU can push beyond 100 FPS when the GPU is not overloaded. The data suggests that the i5-10400F has enough headroom to support the RX 7600 without holding it back, making it a reasonable pairing for this title.
