Microsoft Flight Simulator

Microsoft Flight Simulator is one of the most demanding titles in the benchmark database, and the pairing of the Intel Core i5-13400F with the AMD Radeon RX 570 produces a very specific, and largely predictable, performance profile. The data shows a system that is heavily constrained by the graphics card, particularly at higher resolutions, but one that can still deliver a playable experience if settings are managed carefully. This analysis breaks down the measured results to show exactly where this combo stands and what users can expect.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and tells a clear story about which component is the limiting factor. At 1080p with Low settings, the combo achieves an average of 50.6 FPS. Moving to 1440p drops that to 38.8 FPS, a 23% reduction. Stepping up to 4K further reduces the average to 27.7 FPS, another 29% drop from 1440p. This pattern is consistent across all settings presets, indicating that the rendering load is overwhelming the GPU.

The scaling behavior confirms that the Radeon RX 570 is the primary bottleneck. The 4 GB of GDDR5 memory and the 224.0 GB/s bandwidth are simply not sufficient for the texture and geometry demands of Flight Simulator at higher resolutions. For instance, at 4K Ultra, the average FPS collapses to 14.3, which is effectively a slideshow. The CPU, with its 10 cores and 16 threads, is not the constraint here; the data suggests that even at 1080p, the GPU is working at its limit, as the jump from Low to Ultra at that resolution only yields a 52% performance penalty (from 50.6 to 24.3 FPS), which is more indicative of GPU shader and memory pressure than CPU limitations.

The practical takeaway is that this system is a 1080p machine for this game. The 1440p results are borderline, and 4K is not a viable option for smooth gameplay. The delta between 1080p and 1440p at Low settings is 11.8 FPS, which is a significant loss for a single resolution step. This indicates that users should prioritize resolution over graphical fidelity if they want to maintain a playable frame rate.

FAQ

Q: Can this combo run Microsoft Flight Simulator at 4K?

A: Technically yes, but the experience will be poor. The highest average FPS at 4K is 27.7 on Low settings, and it drops to 14.3 on Ultra. These numbers are below the threshold for smooth, consistent gameplay.

Q: What is the best resolution for this CPU and GPU pairing?

A: The data clearly shows 1920x1080 as the only resolution where the combo approaches acceptable performance. At 1080p, the average FPS ranges from 24.3 on Ultra to 50.6 on Low, making it the only resolution where a playable frame rate is achievable.

Q: How does the RX 570 compare to its nearest rivals in general benchmarks?

A: The RX 570 has an average benchmark score of 30158. Its nearest rival is the NVIDIA GeForce RTX 5060 with a score of 30109, a delta of 0.2%. The AMD Radeon RX 7700 XT is also close with 30097, a 0.2% delta. This indicates that in synthetic tests, these cards are virtually identical in overall capability.

Q: Is the Intel Core i5-13400F a strong CPU for this game?

A: The CPU is not the bottleneck. With a Cinebench R23 multi-core score of 21279 and a single-core score of 3004, it has ample processing power. The benchmark results suggest that the GPU is the limiting factor in Flight Simulator, not the processor.

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

A: At 1080p, the difference is substantial. Low settings produce an average of 50.6 FPS, while Ultra produces 24.3 FPS. This is a 26.3 FPS difference, meaning users must choose between visual fidelity and smoothness.

Q: How does this combo rank against all other tested combinations?

A: The combo ranks 1748 out of 1795 tested combinations for this game. This places it in the bottom 3% of all tested systems, highlighting that it is not a high-performance configuration for this specific title.

How This Combo Ranks

The combo rank of 1748 out of 1795 is a harsh but accurate reflection of this system's capabilities in Microsoft Flight Simulator. It places the i5-13400F and RX 570 in the bottom 2.6% of all tested combinations. This is a very low ranking, and it is almost entirely due to the GPU's limitations. The CPU itself is a solid performer, ranking in the 82nd percentile against all CPUs, but the GPU, while in the 74th percentile against all GPUs, is simply outclassed by the demands of this flight simulator.

When looking at the GPU's nearest rivals, the data shows an interesting anomaly. The RX 570 has an average benchmark score of 30158, which is nearly identical to the NVIDIA GeForce RTX 5060 (30109) and the AMD Radeon RX 7700 XT (30097). Despite this apparent parity in general benchmarks, the RX 570's 4 GB of VRAM is a severe handicap in a game like Flight Simulator, which can easily exceed that capacity at higher settings. This is why the combo ranks so low, despite the components having respectable individual percentile scores. The benchmark data shows that synthetic scores do not always translate to real-world gaming performance, especially in VRAM-intensive scenarios.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across all settings and resolutions. The results are consistent: lower resolutions and lower settings yield higher frame rates, but the overall ceiling is low.

At 1920x1080, the results are as follows:

• Low: 50.6 FPS average
• Medium: 36.4 FPS average
• High: 26.6 FPS average
• Ultra: 24.3 FPS average

At 2560x1440, the performance drops noticeably:

• Low: 38.8 FPS average
• Medium: 28.1 FPS average
• High: 23.8 FPS average
• Ultra: 24.1 FPS average

At 3840x2160, the system is clearly overmatched:

• Low: 27.7 FPS average
• Medium: 19.7 FPS average
• High: 19.2 FPS average
• Ultra: 14.3 FPS average

The data shows that the difference between High and Ultra at 1440p and 4K is minimal, suggesting that the Ultra preset adds graphical features that heavily tax the GPU without providing a meaningful FPS benefit. At 1440p, High yields 23.8 FPS and Ultra yields 24.1 FPS, a negligible difference. This indicates that the GPU is hitting a hard performance wall, likely due to memory bandwidth or VRAM capacity.

Settings Recommendations

Based on the measured data, the only viable path to a smooth experience is to use 1080p with the Low preset. The 50.6 FPS average at this setting is the only result that approaches a standard 60 FPS target, and even then, it is below it. Medium settings at 1080p yield 36.4 FPS, which is playable but may feel sluggish in a simulator where precision is key.

For users who prioritize visual quality over frame rate, 1080p High at 26.6 FPS is an option, but the data suggests that the jump from High to Ultra is not worth the performance cost, as it only delivers a 2.3 FPS difference. At 1440p, the Low preset at 38.8 FPS is the best option, but users should be prepared for a less detailed world. The High and Ultra presets at 1440p are too close to the 20 FPS mark to be recommended for anything other than static screenshots. The 4K results are uniformly poor and should be avoided for active gameplay.

The practical recommendation is to start with 1080p Low and gradually increase settings to Medium if the frame rate is acceptable. The data suggests that this combo cannot handle the higher presets without significant compromises.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor based on the Raptor Lake architecture. It has a base clock of 2.50 GHz and a boost clock of 4.60 GHz. In synthetic benchmarks, it performs well, with a Cinebench R23 multi-core score of 21279 and a single-core score of 3004. Its average benchmark score is 25236, placing it in the 82nd percentile of all CPUs.

In the context of Microsoft Flight Simulator, the CPU's role is to handle the complex simulation logic, including physics, AI traffic, and world generation. The benchmark results indicate that the i5-13400F is more than capable of this task. The FPS scaling from 1080p to 4K is almost entirely a function of GPU load, not CPU load. The CPU's high single-thread performance (Geekbench single-core score of 2301) is crucial for the main simulation thread, and its 16 threads provide ample headroom for background tasks.

The data suggests that the CPU is not the limiting factor in this configuration. Even at 1080p Low, where the GPU is least stressed, the FPS does not jump to a level that would suggest a CPU bottleneck. The performance is consistently capped by the GPU's ability to render frames, not the CPU's ability to calculate them. Therefore, users should not expect any CPU overclocking or upgrade to improve FPS in this game with the RX 570; the graphics card is the definitive bottleneck.
