Microsoft Flight Simulator

The Intel Core i5-11400F paired with the NVIDIA GeForce RTX 5080 is a combination that leans heavily on the GPU’s immense power to overcome a mid-range 2021 processor. In Microsoft Flight Simulator, a title known for its demanding rendering of terrain and weather, this pairing produces surprisingly strong frame rates across all resolutions. The data below breaks down exactly how this system performs, where the bottleneck lies, and which settings deliver the smoothest experience.

Best Settings per Resolution

The benchmark results for this combination show that it clears the 60 FPS playability threshold at every tested resolution, even at the highest preset. The most demanding preset that maintains at least 60 FPS is the "Ultra" quality level across all three resolutions.

At 3840x2160 (4K), the Ultra preset delivers an average of 73.9 FPS. This is the most demanding setting that stays above 60 FPS, making it the best choice for maximum visual fidelity at 4K. The frame rate remains comfortably above the playable threshold, with High settings at 77.2 FPS, Medium at 98.6 FPS, and Low at 132.2 FPS, but Ultra offers the highest quality without dipping below the target.

At 2560x1440 (1440p), the Ultra preset achieves an average of 100.8 FPS. This is a substantial margin above the 60 FPS threshold, indicating that the system has significant headroom at this resolution. The other presets all perform exceptionally well here: High at 105.3 FPS, Medium at 131.3 FPS, and Low at 145.6 FPS. For 1440p gaming, Ultra is not only playable but also delivers a very smooth experience.

At 1920x1080 (1080p), the Ultra preset produces an average of 123.2 FPS. This is well above the 60 FPS line and provides a highly responsive experience. High settings reach 133.1 FPS, Medium hits 144.3 FPS, and Low tops out at 160.1 FPS. The sheer performance at 1080p means that even the most demanding preset is far from stressing the system.

The recorded data indicates that this combination can run the game at its maximum visual settings without compromise at all three resolutions. There is no scenario where the user must lower the preset to achieve playability.

CPU and GPU Roles

The performance scaling across resolutions reveals a clear division of labor between the Intel Core i5-11400F and the NVIDIA GeForce RTX 5080. The CPU, with its 6 cores and 12 threads from the Rocket Lake architecture, provides a solid baseline but is not the primary driver of frame rates in this title. The GPU, a Blackwell 2.0 architecture part with 10752 shading units, is the dominant factor.

Examining the frame rate deltas between resolutions shows that the GPU is heavily taxed as resolution increases, while the CPU's load remains relatively constant. At 1080p, the Ultra preset averages 123.2 FPS. Moving to 1440p, that figure drops to 100.8 FPS, a decline of 22.4 FPS. Moving further to 4K, the Ultra preset falls to 73.9 FPS, another drop of 26.9 FPS. This steep decline with increasing pixel count is a classic sign of a GPU-bound scenario. The RTX 5080 is working harder at each higher resolution, while the CPU is likely not the limiting factor.

Conversely, the difference between presets at the same resolution shows a smaller performance gap. At 4K, the spread between Low and Ultra is 58.3 FPS (132.2 to 73.9). At 1080p, the spread is 36.9 FPS (160.1 to 123.2). This indicates that while the GPU is heavily loaded, the CPU is still capable of feeding it enough data to see substantial gains from lowering graphics settings.

The i5-11400F, despite being an end-of-life product from 2021, holds up adequately. Its single-thread performance, as measured by a Cinebench R23 single-core score of 2024, is sufficient to avoid crippling the RTX 5080. The data suggests that at 1080p, the CPU is more involved in the overall performance equation, but it does not prevent high frame rates. At 4K, the GPU is unequivocally the bottleneck, as the frame rate is primarily determined by the pixel throughput of the RTX 5080.

The benchmark results show that the GPU is the decisive component. The RTX 5080's 960.0 GB/s of memory bandwidth and 56.28 TFLOPS of FP32 compute are the resources being fully utilized at higher resolutions. The CPU's role is to maintain a stable baseline, and it does so without creating a hard limit on performance.

FAQ

Q: Can this PC run Microsoft Flight Simulator at 4K with Ultra settings?

A: Yes. The recorded data shows an average of 73.9 FPS at 3840x2160 with the Ultra preset, which is above the 60 FPS playability threshold.

Q: What is the best settings preset for 1440p gaming?

A: The Ultra preset is the best choice at 2560x1440, delivering an average of 100.8 FPS. All other presets (High, Medium, Low) also exceed 60 FPS.

Q: Is the CPU or GPU more important for this game?

A: The GPU is the dominant factor. The frame rate drops significantly as resolution increases (from 123.2 FPS at 1080p Ultra to 73.9 FPS at 4K Ultra), showing the RTX 5080 is the primary performance driver. The CPU provides a capable baseline but is not the main bottleneck.

Q: How does the RTX 5080 compare to its nearest rivals in this context?

A: The RTX 5080's average benchmark score is 56083. The AMD Radeon 8060S scores 55757 (0.6% slower), the AMD Radeon RX 6750 GRE 12 GB scores 55698 (0.7% slower), and the AMD Radeon Pro W5700X scores 54828 (2.3% slower). The AMD Radeon RX 9070 GRE scores 57367, which is 2.2% faster.

Q: What are the playable settings at 1080p?

A: All presets are playable at 1920x1080. The Ultra preset averages 123.2 FPS, High averages 133.1 FPS, Medium averages 144.3 FPS, and Low averages 160.1 FPS.

Q: Is the Intel Core i5-11400F a weak link in this system?

Similar Performance Alternatives

The hardware database provides a set of nearest rivals for both the CPU and GPU, based on average benchmark scores. These components would behave similarly in terms of raw compute power, though real-world gaming performance can vary.

For the CPU, the Intel Core i5-11400F has an average benchmark score of 17177. The closest rivals are:

• AMD EPYC 7H12: Scores 17120, which is 0.3% slower.
• Intel Core i5-12450H: Scores 17239, which is 0.4% faster.
• AMD Ryzen 3 PRO 8300G: Scores 17278, which is 0.6% faster.
• Intel Core Ultra 7 164U: Scores 17074, which is 0.6% slower.

These processors are all within a very tight performance band. A system with any of these CPUs paired with the RTX 5080 would likely deliver nearly identical frame rates in Microsoft Flight Simulator, as the CPU is not the primary bottleneck.

For the GPU, the NVIDIA GeForce RTX 5080 has an average benchmark score of 56083. The nearest rivals are:

• AMD Radeon 8060S: Scores 55757, which is 0.6% slower.
• AMD Radeon RX 6750 GRE 12 GB: Scores 55698, which is 0.7% slower.
• AMD Radeon Pro W5700X: Scores 54828, which is 2.3% slower.
