Microsoft Flight Simulator

Microsoft Flight Simulator is an exceptionally demanding title that scales heavily with both CPU and GPU resources. The measured data for this configuration, pairing the Intel Core i5-13400F with the NVIDIA GeForce RTX 3080 Ti, shows a system that can deliver smooth, playable frame rates at every resolution, but the optimal settings are highly dependent on your display target. The combo ranks 501st out of 1795 tested configurations, placing it in the top 28% of all systems, which is a strong position for a high-refresh 1440p experience or a solid 4K presentation. The data shows that the RTX 3080 Ti has enough headroom to push high frame rates, but the Ultra preset introduces a significant performance penalty that makes it less practical than High for consistent play.

Settings Recommendations

The measured FPS rows provide a clear hierarchy of performance across the four settings presets. At the highest resolution of 3840x2160, the Ultra preset yields an average of 51.1 FPS, which dips below the 60 FPS target that most flight sim enthusiasts prefer for smooth panning. Dropping to High raises the average to 55.6 FPS, a modest improvement that still leaves the system on the edge of 60 FPS. The Medium preset at 4K produces 72.1 FPS, which is a substantial jump and provides a much more comfortable margin for maintaining fluidity over dense scenery. Low settings push this further to 92.4 FPS, but this comes at a significant cost to visual fidelity in a game where terrain and cockpit detail are central to the experience. The data suggests that Medium is the sweet spot for 4K, offering the best balance between visual quality and a frame rate that stays well clear of the 60 FPS threshold.

Moving to 2560x1440, the situation improves markedly. The Ultra preset averages 72.7 FPS, which is now perfectly playable on a high-refresh monitor, while High jumps to 76.3 FPS. The Medium preset delivers an excellent 101.4 FPS, and Low reaches 129.1 FPS. For 1440p, the High preset appears to be the recommended choice, as it provides a significant visual upgrade over Medium while still maintaining an average above 75 FPS, which is smooth enough for most users. The Ultra preset is viable here, but the 4.8% performance drop from High (76.3 FPS down to 72.7 FPS) is not worth the marginal visual gains in a game that is already visually demanding. At 1920x1080, the CPU begins to assert its influence. High settings average 95.7 FPS, Ultra averages 93.1 FPS, and Medium hits 129.1 FPS. The gap between High and Ultra at 1080p is only 2.7%, indicating that the CPU is becoming the limiting factor, making Ultra the better choice at this resolution if you want maximum fidelity without sacrificing much speed.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor based on the Raptor Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. Its benchmark scores are respectable, with a Cinebench R23 multicore score of 21279 and a single-core score of 3004, placing it in the 82nd percentile against all CPUs. In a flight simulator, the CPU handles the complex flight dynamics, AI traffic, and world simulation, which often requires strong single-thread performance. The data shows that this CPU is capable of keeping up with the RTX 3080 Ti at lower resolutions. At 1080p, the difference between High (95.7 FPS) and Low (163.5 FPS) is substantial, but the difference between High (95.7 FPS) and Ultra (93.1 FPS) is minimal. This indicates that the CPU is hitting a performance ceiling around the 95-100 FPS mark in this title, regardless of the graphics load. The processor's performance is very close to its nearest rivals, with a deltaPct of only 0.1% against the Intel Core i7-13620H and -0.5% against the AMD Ryzen 5 5600X3D, meaning that swapping to those chips would yield no perceptible difference in this game. The 16 threads are sufficient for the simulator's workload, as the scaling from 1080p to 1440p shows a drop from 95.7 FPS to 76.3 FPS on High settings, proving that the GPU is taking on more responsibility as resolution increases, rather than the CPU becoming a bottleneck.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is a powerhouse with 12 GB of GDDR6X memory on a 384-bit bus, providing a massive bandwidth of 912.4 GB/s. Its boost clock of 1665 MHz and 10240 shading units allow it to produce a FP32 compute throughput of 34.10 TFLOPS. This hardware is clearly designed for high-resolution gaming, and the benchmark data confirms its strength in this simulator. The GPU's percentile rank is 83rd against all GPUs, with an average benchmark score of 41224. It sits just 0.5% behind the RTX 3090 and 1.1% behind the RTX 5070 in synthetic tests, showing that it remains a highly competitive part. In the measured FPS data, the GPU's role becomes evident as resolution scales. At 4K, the difference between the Low preset (92.4 FPS) and the Ultra preset (51.1 FPS) is a massive 44.7%, demonstrating that the GPU is the primary driver of frame rate at this resolution, where the 12 GB VRAM buffer and raw shader throughput are fully exercised. The 4K performance is solid but not overwhelming; the 55.6 FPS at High settings is just shy of a locked 60 FPS, which is why the Medium preset is recommended for 4K displays. At 1440p, the GPU has more headroom, allowing for the High preset to achieve 76.3 FPS, which is a comfortable experience. The card's 350 W TDP and 750 W suggested PSU indicate it is a power-hungry component, but its end-of-life production status and predecessor to the GeForce 40 series mean it is still a relevant option for this game.

Q: Can this system achieve 60 FPS at 4K with High settings?

A: No. The measured average FPS for the High preset at 3840x2160 is 55.6 FPS, which is below the 60 FPS target. You would need to drop to Medium settings, which average 72.1 FPS, to comfortably exceed 60 FPS.

Resolution Scaling

The measured FPS data shows a clear and predictable scaling pattern as resolution increases. On the High preset, the system achieves 95.7 FPS at 1920x1080, drops to 76.3 FPS at 2560x1440 (a 20.3% decrease), and further drops to 55.6 FPS at 3840x2160 (a 27.1% decrease from 1440p). This progressive decline indicates that the GPU is the dominant factor in frame rate scaling, as its workload increases with pixel count. The Low preset shows a similar trend, falling from 163.5 FPS at 1080p to 129.1 FPS at 1440p, and then to 92.4 FPS at 4K. The consistency of these drops across all settings presets confirms that the RTX 3080 Ti is the primary performance limiter as resolution increases. However, the behavior at 1080p is revealing. The fact that the Ultra preset (93.1 FPS) is only 2.7% slower than High (95.7 FPS) at 1080p, but 8.1% slower at 4K (51.1 FPS vs 55.6 FPS), shows that at lower resolutions, the CPU's capability to feed the GPU becomes the limiting factor. The scaling from 1080p to 4K on the Ultra preset is a 45.1% drop (from 93.1 FPS to 51.1 FPS), which is slightly less severe than the High preset's 41.9% drop, suggesting that the Ultra preset's extra GPU load masks the CPU bottleneck at higher resolutions.
