Microsoft Flight Simulator

Intel Core i9-14900K and NVIDIA GeForce RTX 4080 delivers a decisive performance verdict in Microsoft Flight Simulator: this combination is fully capable of running the game at maximum visual fidelity across all tested resolutions, with 4K Ultra producing a measured 70 FPS average. The data shows a system that never drops below the 60 FPS playable threshold, even at the most demanding settings, making it a top-tier pairing for this simulator.

Measured FPS Breakdown

At 1920x1080, the Intel Core i9-14900K and NVIDIA GeForce RTX 4080 produce exceptional frame rates that scale predictably with preset selection. The Low preset achieves a 211 FPS average, which represents the highest measured performance in the entire dataset. Moving to Medium, the average settles at 164 FPS with a minimum of 139 FPS and a maximum of 188 FPS, indicating a 22.3% drop from Low. High delivers 123 FPS average, a further 25% reduction from Medium. Ultra remains highly playable at 117 FPS average, which is only 4.9% below the High preset, showing that the most demanding settings exact a relatively small performance penalty at this resolution.

At 2560x1440, the scaling pattern continues but with tighter margins between presets. Low produces 170 FPS average, which is 19.4% lower than the 1080p Low result, demonstrating the resolution's impact on the CPU-GPU pipeline. Medium achieves 132 FPS average with a minimum of 112 FPS and a maximum of 152 FPS, representing a 22.4% drop from Low. High reaches 99 FPS average, a 25% reduction from Medium. Ultra delivers 95 FPS average, which is just 4% below High, mirroring the 1080p relationship between these two presets. The minimum recorded value of 112 FPS at Medium confirms that even transient frame dips remain comfortably above the 60 FPS threshold.

At 3840x2160, the RTX 4080's 16 GB GDDR6X memory and 716.8 GB/s bandwidth become critical factors. Low produces 125 FPS average, a 26.5% decrease from 1080p Low, highlighting the increased pixel throughput demand. Medium achieves 97 FPS average with a minimum of 83 FPS and a maximum of 112 FPS, representing a 22.4% drop from Low. High reaches 73 FPS average, a 24.7% reduction from Medium. Ultra delivers 70 FPS average, which is 4.1% below High. The 83 FPS minimum at Medium is the lowest recorded minimum across all resolutions and presets, yet it still clears the playable threshold by a substantial 23 FPS margin.

Best Settings per Resolution

At 1920x1080, the Ultra preset is the optimal choice, delivering a 117 FPS average. This represents the highest visual quality while maintaining a 95% margin above the 60 FPS playable threshold. The data shows no reason to compromise on settings at this resolution, as even the most demanding preset provides headroom for complex flight scenarios.

At 2560x1440, Ultra again emerges as the best setting with a 95 FPS average. The performance gap between High and Ultra is only 4 FPS, making the upgrade to maximum settings essentially free. This resolution offers the best balance of visual density and frame rate, with Ultra still 58.3% above the playable threshold.

At 3840x2160, Ultra remains the recommended setting with a 70 FPS average. While this is the lowest recorded average across all resolution-preset combinations, it still exceeds the 60 FPS threshold by 16.7%. The verdict data confirms that all four presets — Low, Medium, High, and Ultra — are playable at 4K, with Ultra providing the definitive visual experience without sacrificing smoothness.

CPU and GPU Roles

The benchmark data reveals a clear shift in component bottleneck behavior across resolutions. At 1920x1080, the Intel Core i9-14900K's 24 cores and 32 threads, combined with its 6.00 GHz boost clock, provide ample single-thread performance for Microsoft Flight Simulator's simulation logic. The CPU's 95th percentile ranking among all processors indicates that it is not the limiting factor at this resolution. The 44.6% performance delta between Low (211 FPS) and Ultra (117 FPS) suggests that GPU workload scaling dominates the frame rate equation.

At 2560x1440, the GPU begins to assert greater influence. The RTX 4080's 48.74 TFLOPS FP32 compute and 280.6 GPixel/s pixel rate are increasingly taxed by the higher pixel count. The performance drop from 1080p to 1440p at Low preset is 19.4%, while at Ultra it is 18.8%, indicating a consistent GPU-limited scaling pattern. The CPU's role diminishes relative to the GPU, but the i9-14900K's strong single-core performance (2262.5 in Cinebench R23 single-core) ensures that simulation overhead does not create stutter.

At 3840x2160, the RTX 4080 is unequivocally the dominant component. The 4K Low average of 125 FPS represents a 40.8% reduction from 1080p Low, demonstrating the exponential cost of pixel throughput. The GPU's 716.8 GB/s memory bandwidth and 16 GB VRAM capacity are essential for handling 4K textures and complex scenery. The CPU's role at this resolution is reduced to maintaining frame pacing, which the i9-14900K handles with its 36 MB shared L3 cache and high boost clocks. The scaling between Medium (97 FPS) and Ultra (70 FPS) at 4K shows a 27.8% performance cost for the highest settings, confirming that GPU fill rate and shading throughput are the primary constraints.
