Microsoft Flight Simulator

The Intel Core i5-14600KF paired with the NVIDIA GeForce RTX 4080 delivers a decisive performance profile in Microsoft Flight Simulator, with benchmark results showing that every tested resolution and preset combination clears the 60 FPS playability threshold. The data indicates a system with substantial headroom, where even the most demanding "Ultra" settings remain comfortably above playable frame rates across 1080p, 1440p, and 4K resolutions. This analysis examines the measured FPS data to determine optimal settings, component workload distribution, and how this combination ranks against other tested hardware.

Best Settings per Resolution

At 1920x1080, the data shows that "Ultra" settings produce an average of 117 FPS, which is the highest preset that maintains performance above the 60 FPS threshold. The frame rate scaling is linear and generous: "Low" produces 211 FPS, "Medium" averages 164 FPS, and "High" reaches 123 FPS. Since all presets at this resolution exceed 60 FPS by a wide margin, the "Ultra" setting is the clear recommendation for maximum visual fidelity without sacrificing smoothness.

Moving to 2560x1440, the "Ultra" preset again stands as the best choice, delivering an average of 95 FPS. The progression from "Low" (170 FPS) through "Medium" (132 FPS) to "High" (99 FPS) shows a consistent step-down of roughly 30-40 FPS per tier, but even the most demanding setting retains a 35 FPS cushion above the playability threshold. The 1440p resolution demonstrates that this hardware combination has ample performance to spare, making "Ultra" the only sensible recommendation for users prioritizing image quality.

At 3840x2160, the situation becomes more nuanced. The "Ultra" preset averages 70 FPS, which still clears the 60 FPS bar but with a narrower margin of just 10 FPS. The "High" preset averages 73 FPS, "Medium" reaches 97 FPS, and "Low" hits 125 FPS. Interestingly, the difference between "High" and "Ultra" at 4K is only 3 FPS (73 vs 70), suggesting that the "Ultra" preset's additional graphical demands are well within the GPU's capabilities at this resolution. The data supports "Ultra" as the best setting at 4K, but users sensitive to frame rate fluctuations might prefer "High" for its slightly higher average and the fact that "Medium" shows a minimum of 83 FPS, indicating better frame pacing stability.

CPU and GPU Roles

The workload distribution between the Intel Core i5-14600KF and the RTX 4080 becomes evident when comparing frame rates across resolutions and presets. At 1920x1080, the gap between "Low" (211 FPS) and "Ultra" (117 FPS) is 94 FPS, representing a 45% performance drop when maxing out graphical settings. This substantial scaling indicates that the GPU is the dominant bottleneck at lower resolutions, where the CPU's 14 cores and 20 threads (boost clock 5.30 GHz) can feed frames faster than the graphics card can render them.

At 2560x1440, the "Low" to "Ultra" spread narrows to 75 FPS (170 down to 95), a 44% reduction. The proportional similarity to 1080p suggests that the GPU workload is scaling consistently with pixel count, while the CPU maintains its ability to supply draw calls and simulation data. Microsoft Flight Simulator's complex flight model and world-streaming systems are known to stress processors, and the i5-14600KF's strong single-thread performance (evidenced by a Cinebench R23 single-core score of 4594) appears sufficient to keep pace.

The 3840x2160 results tell a different story. Here, "Low" produces 125 FPS and "Ultra" drops to 70 FPS, a 55 FPS or 44% reduction. However, the absolute frame rates at 4K are significantly lower than at 1440p for the same settings — "Ultra" drops from 95 to 70 FPS (26% reduction) when moving from 1440p to 4K. This scaling pattern indicates that at 4K, the RTX 4080's pixel throughput becomes the limiting factor, whereas at 1080p and 1440p, the CPU's simulation overhead plays a more visible role. The GPU's 16 GB of GDDR6X memory and 716.8 GB/s bandwidth provide ample headroom for high-resolution textures, but the raw pixel rate of 280.6 GPixel/s sets a ceiling that becomes noticeable at 4K Ultra.

The data implies that for users targeting 1080p or 1440p, the i5-14600KF is sufficient to avoid CPU-induced frame drops, while the RTX 4080's performance scales predictably with resolution. At 4K, the GPU becomes the primary constraint, and the CPU's contribution diminishes relative to the graphics workload.

The verdictByResolution data confirms that all four playable settings — "Low", "Medium", "High", and "Ultra" — are viable at every resolution tested. The weakest point in the entire dataset is 4K "Ultra" at 70 FPS average, which still comfortably exceeds the 60 FPS threshold. For users who prioritize frame rate stability over absolute visual fidelity, the 4K "Medium" preset offers a minimum observed FPS of 83, providing stronger assurance against drops during dense scenery or complex weather scenarios.

This is a system with significant headroom. The 1080p "Ultra" result of 117 FPS suggests that even with future game updates that increase graphical demands, there is room before the hardware becomes marginal. The RTX 4080's position in the 86th percentile of all GPUs and the i5-14600KF's 90th percentile CPU ranking support the conclusion that this combination is well-matched for this simulator's unique blend of CPU-intensive simulation and GPU-heavy rendering.

Similar Performance Alternatives

For the CPU, the nearest rivals by average benchmark score are the AMD Ryzen 9 7900 with a score of 49228 (0.3% lower than the i5-14600KF's 49394), the AMD Ryzen 7 PRO 5755G at 49196 (0.4% lower), the Intel Core Ultra 5 245 at 48995 (0.8% lower), and the AMD Ryzen AI Max+ 388 at 49796 (0.8% higher). These processors would deliver near-identical simulation performance in Microsoft Flight Simulator, with the Ryzen AI Max+ 388 offering a marginal edge and the Core Ultra 5 245 trailing slightly.

On the GPU side, the RTX 4080's closest competitor is the NVIDIA GeForce RTX 4080 SUPER, which scores 54209 against the RTX 4080's 54247 — a negligible 0.1% difference. The AMD Radeon Pro W5700X scores 1.1% higher, while the AMD Radeon RX 6750 GRE 12 GB and AMD Radeon 8060S score 2.6% and 2.7% higher respectively. These delta values are small enough that in-game frame rates would be nearly indistinguishable, though the RTX 4080's 16 GB VRAM and 76 RT cores provide architectural advantages that synthetic benchmarks may not fully capture.

Users considering alternatives should note that while the AMD Radeon RX 6750 GRE 12 GB shows a higher average benchmark score, it is a different class of product with different memory characteristics. The practical takeaway is that the RTX 4080 SUPER is the most direct drop-in equivalent, while the AMD options offer competitive compute performance but potentially different driver-level behavior in DirectX 12 titles.

How This Combo Ranks

Among 3714 tested CPU-GPU combinations for Microsoft Flight Simulator, this configuration ranks 215th overall. This places it comfortably in the top tier of tested systems — roughly the top 6% of all combinations. The ranking reflects the balance between the i5-14600KF's strong single-thread performance (Cinebench R23 single-core score of 4594) and the RTX 4080's substantial rasterization throughput (48.74 TFLOPS FP32).

The rank of 215 out of 3714 suggests that while there are 214 combinations that perform better, the vast majority of systems tested will deliver lower frame rates. The data implies that this combo sits in a performance tier where the limiting factor is no longer raw hardware capability but rather the game's engine optimizations and the diminishing returns of ever-higher-end components. The 4K "Ultra" average of 70 FPS, combined with the 1080p "Ultra" result of 117 FPS, indicates a system that can handle the simulator's most demanding scenarios without compromise.
