Microsoft Flight Simulator

Intel Core i5-14600K and NVIDIA GeForce RTX 5080 is a high-end combination that delivers consistently smooth frame rates in Microsoft Flight Simulator across all tested resolutions and presets. Benchmark data shows this pairing clears the 60 FPS playability threshold at every setting, with the worst-case scenario being 72 FPS at 4K Ultra. The measured FPS results reveal a system that scales predictably with resolution and graphical load, offering headroom for demanding flight scenarios.

Measured FPS Breakdown

At 1920x1080, the combo produces exceptional frame rates that exceed the needs of any current display. Low settings deliver an average of 218 FPS, Medium averages 170 FPS with a minimum of 144 FPS and maximum of 195 FPS, High averages 128 FPS, and Ultra averages 122 FPS. Even the most demanding preset at 1080p provides more than double the 60 FPS playable threshold, making this resolution almost trivial for the hardware.

Moving to 2560x1440, performance remains strong but shows the expected scaling. Low settings hit 176 FPS average, Medium averages 137 FPS with a range of 116 to 157 FPS, High averages 103 FPS, and Ultra averages 98 FPS. The gap between Low and Ultra narrows to 78 FPS at this resolution, compared to 96 FPS at 1080p, indicating the GPU is becoming a more significant factor as pixel count rises.

At 3840x2160, the data shows the most demanding workload. Low settings still produce 130 FPS average, Medium averages 101 FPS with a minimum of 86 FPS and maximum of 116 FPS, High averages 76 FPS, and Ultra averages 72 FPS. The minimum FPS at 4K Medium (86) and the average at 4K Ultra (72) both stay comfortably above 60 FPS, but the margin shrinks considerably compared to lower resolutions.

The Medium settings entries are the only ones with complete min/max data, which provides insight into frame pacing. At 1080p Medium, the 144-195 FPS range shows a 51 FPS spread. At 1440p Medium, the range is 116-157 FPS, a 41 FPS spread. At 4K Medium, the range is 86-116 FPS, a 30 FPS spread. This narrowing range at higher resolutions suggests that GPU-bound scenarios produce more consistent frame times than CPU-bound ones.

How This Combo Ranks

The combination of Intel Core i5-14600K and NVIDIA GeForce RTX 5080 achieves rank 171 out of 3714 tested combos in Microsoft Flight Simulator. This places the system in the top 4.6% of all configurations tested for this game. The rank reflects the strong synergy between the CPU and GPU, with the measured FPS data showing that the system handles even the most demanding 4K Ultra settings without dropping below 60 FPS.

The percentile standing is consistent with the component-level data. The CPU sits at the 90th percentile against all CPUs, and the GPU sits at the 87th percentile against all GPUs. The combo rank of 171 out of 3714 suggests that the pairing performs slightly better than the individual percentiles might indicate, likely due to the balanced nature of the two components.

For context, the top 171 out of 3714 means there are 3543 tested combinations that rank lower. This is a strong result for a flight simulator, which is known for being particularly demanding on both CPU and GPU. The data indicates that this combo is better suited to this workload than most of the tested hardware pairings.

Similar Performance Alternatives

The CPU's nearest rivals, based on average benchmark scores, offer nearly identical compute performance. The Intel Xeon Gold 5318H scores 48698, which is only 0.2% higher than the i5-14600K's 48618 average. The AMD EPYC 4345P scores 48470, a 0.3% difference. The Intel Core Ultra 5 245HX scores 48287, a 0.7% difference. The Intel Core Ultra 5 245 scores 48995, a 0.8% difference. All four alternatives fall within a 1% performance band, so swapping the CPU would produce negligible changes in game performance.

On the GPU side, the nearest rivals show slightly more variance. The AMD Radeon 8060S scores 55757, which is 0.6% lower than the RTX 5080's 56083 average. The AMD Radeon RX 6750 GRE 12 GB scores 55698, a 0.7% difference. The AMD Radeon Pro W5700X scores 54828, a 2.3% difference. The AMD Radeon RX 9070 GRE scores 57367, which is 2.2% higher than the RTX 5080. The RX 9070 GRE would be the closest performance upgrade, while the Pro W5700X would be the most noticeable downgrade.

For practical purposes, any of the CPU alternatives would deliver essentially the same frame rates in Microsoft Flight Simulator, given the 1% or smaller score deltas. The GPU alternatives are also close, with the largest gap being 2.3%, which would translate to roughly 1-2 FPS difference at the measured settings.

CPU and GPU Roles

The scaling between resolutions reveals how the workload shifts between CPU and GPU. At 1920x1080, the average FPS across all presets is substantially higher than at 3840x2160, with Low settings showing a 218 FPS versus 130 FPS difference. This 88 FPS gap at Low settings points to the GPU becoming the limiting factor at higher resolutions, since the CPU workload is relatively constant regardless of pixel count.

The preset scaling at each resolution provides additional insight. At 1080p, moving from Low to Ultra reduces average FPS by 96 FPS (from 218 to 122). At 1440p, the same preset change reduces FPS by 78 FPS (from 176 to 98). At 4K, the reduction is 58 FPS (from 130 to 72). The smaller absolute drop at higher resolutions indicates that the GPU is already heavily loaded, so preset changes have less relative impact.

The i5-14600K, with its 14 cores and 20 threads, provides strong single-thread performance as evidenced by its Cinebench R23 single-core score of 2064 and Geekbench single-core score of 2491. Microsoft Flight Simulator benefits from this strong single-thread capability for simulation logic, while the GPU handles the rendering load. At 1080p, the CPU is more likely to be a factor, as evidenced by the larger FPS differences between presets. At 4K, the RTX 5080's 960.0 GB/s memory bandwidth and 56.28 TFLOPS FP32 performance become the dominant factors.

The data suggests that at 1080p, the CPU and GPU are more balanced, with neither being a clear bottleneck. At 1440p, the GPU begins to take on more responsibility, and at 4K, the GPU is clearly the primary performance driver. The 72 FPS average at 4K Ultra indicates the RTX 5080 is working near its limits, while the CPU still has headroom.

The Verdict

This PC can run Microsoft Flight Simulator with playable performance at every resolution and preset combination tested. The verdict data confirms that all four settings presets at all three resolutions clear the 60 FPS threshold.

At 1920x1080, the best settings are Ultra with an average of 122 FPS. At 2560x1440, Ultra is also the best choice, averaging 98 FPS. At 3840x2160, Ultra remains the best setting with a 72 FPS average. The system never falls below 60 FPS in any measured configuration, with the lowest recorded minimum being 86 FPS at 4K Medium.

For flight simulation, where frame rate dips can occur during complex scenery loading or dense urban areas, the headroom above 60 FPS provides a safety margin. The 72 FPS average at 4K Ultra means the system is operating at 120% of the playable threshold, leaving room for demanding scenarios without dropping below playable levels. At 1440p and 1080p, the margins are even larger, with the system running at 163% and 203% of the threshold respectively at Ultra settings.

This is a capable configuration for Microsoft Flight Simulator at all tested settings. The combination of the i5-14600K's strong single-thread performance and the RTX 5080's high-end rendering capability ensures smooth gameplay across the board. Users with 4K displays can confidently use Ultra settings, while those with high-refresh-rate 1440p or 1080p monitors will find plenty of performance headroom.
