Microsoft Flight Simulator

The Intel Core i5-13400F paired with the NVIDIA GeForce RTX 5080 delivers a decisive performance outcome for Microsoft Flight Simulator, clearing the 60 FPS threshold at every resolution and preset combination tested. The data, measured directly, shows a system that is not merely playable but offers substantial headroom for the most demanding visual settings, making it a top-tier configuration for this flight simulation title.

Best Settings per Resolution

At 3840x2160, the system achieves its maximum playable fidelity at the Ultra preset, which runs at an average of 72.7 FPS. This is the most demanding setting that stays above the 60 FPS playable threshold, and it does so with a comfortable margin. The High preset at this resolution delivers 73.5 FPS, showing that the jump from High to Ultra costs only 0.8 FPS on average, making Ultra the clear choice for 4K gaming.

Moving to 2560x1440, the Ultra preset is again the optimal selection, producing an average of 101.3 FPS. This represents a substantial 39.4% performance increase over the 4K Ultra result, demonstrating that the RTX 5080 scales exceptionally well when pixel count drops. The gap between High (101.8 FPS) and Ultra (101.3 FPS) at this resolution is negligible, confirming Ultra as the preferred setting for 1440p displays.

At 1920x1080, the Ultra preset achieves 125.7 FPS, providing the highest refresh-rate experience among the three resolutions. Interestingly, the scaling from 1440p to 1080p yields a 24.1% improvement in Ultra settings, which is less dramatic than the 1440p to 4K jump. This suggests the system begins to encounter diminishing returns at lower resolutions, where the CPU’s role becomes more pronounced.

CPU and GPU Roles

The benchmark data reveals a clear shift in component responsibility as resolution changes. At 3840x2160, the GPU is the dominant factor, evidenced by the relatively small performance delta between presets. The spread from Low (129.9 FPS) to Ultra (72.7 FPS) at 4K is 57.2 FPS, indicating that the RTX 5080’s rendering workload is the primary bottleneck, while the i5-13400F has ample headroom to feed the GPU.

At 2560x1440, the balance begins to tip. The Low preset jumps to 175.7 FPS, a 35.3% improvement over the 4K Low figure, while Ultra only gains 39.4% over its 4K counterpart. This asymmetric scaling suggests the CPU is starting to influence performance more significantly at lower resolutions, particularly in less demanding presets where the GPU can render frames faster than the processor can dispatch draw calls.

The 1920x1080 results confirm this trend. Low settings at 1080p reach 190.4 FPS, but the gap between Medium (173.9 FPS) and Ultra (125.7 FPS) narrows compared to higher resolutions. The data shows that at 1080p, the i5-13400F’s 10 cores and 16 threads become a more relevant factor, as the GPU’s frame production outpaces the CPU’s ability to maintain scene complexity. The 4.60 GHz boost clock helps, but the architecture’s limits are visible in the reduced scaling from 1440p to 1080p.

Measured FPS Breakdown

At 3840x2160, the full settings ladder shows a predictable decline. Low settings produce 129.9 FPS, which drops to 102 FPS at Medium, a 21.5% reduction. High settings yield 73.5 FPS, and Ultra settles at 72.7 FPS. The most significant performance cliff occurs between Medium and High, a 28.5 FPS drop, while the High-to-Ultra transition costs only 0.8 FPS, indicating that the Ultra preset’s additional effects are largely GPU-bound but well-optimized.

The 2560x1440 measurements follow a similar pattern but with higher absolute values. Low runs at 175.7 FPS, Medium at 139.5 FPS (a 20.6% reduction), High at 101.8 FPS, and Ultra at 101.3 FPS. The Medium-to-High transition again shows the largest drop at 37.7 FPS, while High and Ultra remain nearly identical, differing by just 0.5 FPS. This consistency suggests the Ultra preset at 1440p is not meaningfully more demanding than High in this title.

At 1920x1080, the numbers climb further. Low achieves 190.4 FPS, Medium follows at 173.9 FPS, High at 129.8 FPS, and Ultra at 125.7 FPS. The relative drop from Low to Medium is only 8.7%, the smallest among all resolutions, which reinforces the CPU-limited nature of 1080p gaming. The High-to-Ultra delta remains minimal at 4.1 FPS, confirming that the RTX 5080 handles the Ultra preset’s extra load without significant frame loss.

Similar Performance Alternatives

For the Intel Core i5-13400F, the nearest rivals in aggregate benchmark scores include the AMD Ryzen 9 6900HS, which matches the Intel chip with a 0% deltaPct, and the Intel Core 5 120, which trails by 0.3%. The AMD Ryzen 5 5600X3D also sits 0.3% behind, while the AMD Ryzen 7 6800H leads by 0.4%. These alternatives would deliver nearly identical CPU-bound performance in Microsoft Flight Simulator, meaning users with any of these processors can expect similar frame rates in CPU-limited scenarios at 1080p.

On the GPU side, the NVIDIA GeForce RTX 5080’s nearest competitors include the AMD Radeon 8060S, which scores 0.6% higher, and the AMD Radeon RX 6750 GRE 12 GB, which is 0.7% ahead. The AMD Radeon Pro W5700X trails by 2.3%, while the AMD Radeon RX 9070 GRE is 2.2% faster. These deltas are small enough that real-world gaming performance would be virtually indistinguishable, although the RTX 5080’s 16 GB of GDDR7 memory provides a capacity advantage over the 12 GB RX 6750 GRE in texture-heavy flight scenarios.

The similarity in scores across these rivals means that swapping any of these components would not materially alter the FPS figures reported for this combo, assuming no other system bottlenecks. The data suggests that the i5-13400F and RTX 5080 combination is well-balanced, with neither component leaving significant performance on the table relative to its closest peers.

How This Combo Ranks

The Intel Core i5-13400F and NVIDIA GeForce RTX 5080 combination ranks 193rd out of 3,714 tested combos in Microsoft Flight Simulator, placing it in the top 5.2% of all configurations. This percentile ranking reflects the system’s strong overall performance, particularly given that the i5-13400F is a mid-range CPU by its 77th percentile standing among all processors, while the RTX 5080 sits in the 87th percentile among GPUs.

The rank of 193 is notable because it demonstrates that the combo outperforms many systems with more expensive CPUs, thanks to the RTX 5080’s raw power. The GPU’s 56.28 TFLOPS of FP32 performance and 960.0 GB/s of memory bandwidth drive the high frame rates, while the CPU’s 20 MB of L3 cache and 10 cores provide sufficient support without becoming a liability. The combination’s position in the top 200 reflects the RTX 5080’s ability to carry the system in this GPU-intensive title.

The Verdict

The data is unambiguous: this PC can run Microsoft Flight Simulator at playable frame rates across all tested resolutions. At 3840x2160, the Ultra preset maintains 72.7 FPS, comfortably above the 60 FPS threshold, and all four settings (Low, Medium, High, Ultra) are playable. The system’s best 4K experience is at Ultra, given the negligible difference from High.

At 2560x1440, the verdict is even more favorable. Ultra settings run at 101.3 FPS, providing a high-refresh-rate experience on 1440p monitors, and every preset from Low to Ultra exceeds 100 FPS. The 175.7 FPS Low result offers headroom for competitive or fast-paced flight scenarios, though the game’s simulation nature favors the visual fidelity of Ultra.

At 1920x1080, the system excels with 125.7 FPS at Ultra, making it suitable for 120Hz displays. The 190.4 FPS Low result is the highest recorded figure, but the Ultra preset’s 125.7 FPS is the recommended target for most users. The verdict across all resolutions is a definitive pass, with the RTX 5080 and i5-13400F delivering a smooth, high-fidelity experience in Microsoft Flight Simulator without requiring compromises on visual settings.
