Microsoft Flight Simulator

Resolution Scaling

The measured frame rates for Microsoft Flight Simulator with the Intel Core Ultra 7 270K Plus and NVIDIA GeForce RTX 4080 reveal a clear pattern: this game is heavily GPU-bound at higher resolutions, but the CPU still matters at 1080p. Moving from 1920x1080 to 2560x1440 at High settings drops the average frame rate from 123 FPS to 99 FPS, a 19.5% reduction. The step from 2560x1440 to 3840x2160 is even more punishing, falling from 99 FPS to 73 FPS, another 26.3% decline. Across the full resolution range at High settings, the total loss from 1080p to 4K is 50 FPS, or roughly 40.7% of the 1080p performance.

At Low settings, the scaling is steeper in absolute terms but proportionally similar: 211 FPS at 1080p, 170 FPS at 1440p, and 125 FPS at 4K. That represents a 40.8% drop from 1080p to 4K, nearly identical to the High setting drop. The fact that Low settings still lose 86 FPS between 1080p and 4K indicates that even with reduced graphical load, the RTX 4080's rendering pipeline becomes the limiting factor as pixel count rises.

The Medium preset tells a more complete story because it includes min and max FPS data. At 1920x1080 Medium, the average is 164 FPS with a min of 139 and max of 188. At 2560x1440 Medium, the average falls to 132 FPS with min 112 and max 152. At 3840x2160 Medium, the average drops to 97 FPS with min 83 and max 112. The spread between min and max FPS remains consistent at roughly 29-30 FPS across all three resolutions, suggesting that frame pacing is stable and the bottleneck shifts smoothly rather than causing stutter.

Ultra settings produce the lowest frame rates at every resolution: 117 FPS at 1080p, 95 FPS at 1440p, and 70 FPS at 4K. The 4K Ultra result of 70 FPS is just above the 60 FPS threshold for smooth flight simulation, but the 1080p Ultra result of 117 FPS shows that even at the highest preset, the CPU is not the primary constraint at lower resolutions. The data indicates that the limiting component changes character: at 1080p, the RTX 4080 can push over 200 FPS on Low, which means the Core Ultra 7 270K Plus is keeping up with the GPU's output. At 4K, the GPU's pixel throughput becomes the dominant factor, as evidenced by the 125 FPS Low result versus 70 FPS Ultra.

CPU Role

The Intel Core Ultra 7 270K Plus brings substantial compute resources to this flight simulator. With 24 cores and 24 threads, the processor relies on raw core count rather than simultaneous multithreading. The base clock of 3.70 GHz and boost clock of 5.50 GHz provide a wide dynamic range, allowing the CPU to scale frequency based on the workload's demands.

Benchmark data places this CPU in the 96th percentile among all tested processors, with an average benchmark score of 93,785. Its nearest rivals in the synthetic benchmarks are the Intel Xeon 6520P with a nearly identical score of 93,786 (0% delta), the AMD EPYC 4564P at 95,183 (-1.5% delta), the AMD EPYC 9175F at 95,615 (-1.9% delta), and the AMD EPYC 4565P at 95,764 (-2.1% delta). This clustering indicates the Core Ultra 7 270K Plus sits at the edge of a performance tier dominated by server-class EPYC processors.

For Microsoft Flight Simulator specifically, the CPU's role is evident in the 1080p Low result of 211 FPS. Flight simulation workloads involve complex physics calculations, world geometry loading, and AI traffic management, all of which rely on CPU throughput. The 24-core configuration with 24 threads is well-suited for the parallel tasks in this game, though the absence of hyperthreading means each core handles one thread at a time. The 36 MB of shared L3 cache and 3 MB per-core L2 cache help keep frequently accessed data close to the execution units, reducing memory latency in compute-heavy scenes.

The Cinebench results reinforce the CPU's capability: R23 multicore scores 44,253, while single-core scores 2,439. The multicore-to-single-core ratio of roughly 18.1:1 demonstrates excellent scaling across the 24 cores, which matters for a game that can distribute tasks across many threads. PassMark multithread score of 68,574 and single-thread score of 5,068 further confirm this balance. The PassMark physics score of 4,064 is particularly relevant to flight simulation, as physics calculations are a core component of the game's simulation loop.

Memory bandwidth of 115.2 GB/s via dual-channel DDR5 support provides adequate data throughput for the CPU's many cores. The PCIe Gen 5 interface with 20 CPU lanes ensures the GPU can communicate with the processor without bandwidth constraints, though the RTX 4080 uses a PCIe 4.0 x16 interface. The 125 W TDP suggests the CPU can maintain high clocks under sustained load without excessive thermal throttling, which is important for long flight sessions where the simulation never pauses.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce an average of 211 FPS, which is the single highest measured result in the entire dataset. Medium settings average 164 FPS with a minimum of 139 FPS and maximum of 188 FPS. High settings average 123 FPS, and Ultra settings average 117 FPS. The difference between High and Ultra at 1080p is only 6 FPS, suggesting diminishing returns from the highest preset at this resolution.

Moving to 2560x1440, the performance drops are consistent across presets. Low averages 170 FPS, Medium averages 132 FPS with min 112 and max 152, High averages 99 FPS, and Ultra averages 95 FPS. The gap between High and Ultra narrows further to 4 FPS at 1440p, indicating that the Ultra preset's additional graphical features have less impact on frame rate as resolution increases. The Medium preset's min-to-max range of 40 FPS (112 to 152) shows more variance than at 1080p, where the range was 49 FPS (139 to 188).

At 3840x2160, the frame rates settle into a lower band. Low averages 125 FPS, Medium averages 97 FPS with min 83 and max 112, High averages 73 FPS, and Ultra averages 70 FPS. The High-to-Ultra difference at 4K is just 3 FPS, meaning the Ultra preset's extra settings cost almost nothing in performance at this resolution while providing the highest visual fidelity. The Medium preset at 4K delivers 97 FPS, which is higher than the High preset's 73 FPS, showing that the step from Medium to High is more demanding than from High to Ultra.

Across all resolutions, the Medium preset provides the only complete dataset with min and max FPS values. This reveals that frame time consistency is maintained: the min-to-max spread is 49 FPS at 1080p, 40 FPS at 1440p, and 29 FPS at 4K. The narrowing spread at higher resolutions indicates that the GPU becomes more consistently saturated, reducing frame time variance. The 4K Medium result of 97 FPS average with 83 FPS minimum is particularly strong for flight simulation, where maintaining a minimum above 60 FPS is critical for smooth camera panning and landing approaches.

How This Combo Ranks

This specific combination of the Intel Core Ultra 7 270K Plus and NVIDIA GeForce RTX 4080 ranks 215th out of 3,714 tested combinations in Microsoft Flight Simulator. That places it in the top 5.8% of all recorded systems, a strong result for a desktop configuration with a 125 W CPU and 320 W GPU.

The GPU alone holds the 86th percentile among all tested graphics cards, with an average benchmark score of 54,247. Its nearest rivals in the GPU benchmark are the NVIDIA GeForce RTX 4080 SUPER at 54,209 (0.1% delta), the AMD Radeon Pro W5700X at 54,828 (-1.1% delta), the AMD Radeon RX 6750 GRE 12 GB at 55,698 (-2.6% delta), and the AMD Radeon 8060S at 55,757 (-2.7% delta). The RTX 4080 sits just below the 4080 SUPER in synthetic performance, and the game ranking reflects this competitive positioning.

The CPU's 96th percentile rank is higher than the GPU's 86th percentile, suggesting the processor is relatively stronger in the broader benchmark landscape. However, in this game, the combo ranking of 215 out of 3,714 is driven more by the GPU's ability to render the complex scenery and weather effects that Microsoft Flight Simulator presents. The CPU's strong single-thread performance, evidenced by 2,439 in Cinebench R23 single-core, helps maintain high frame rates in CPU-bound scenarios like dense urban areas or when the simulation calculates weather and physics.

Comparing the two components' rival sets, the CPU and GPU both sit in the middle of their respective performance tiers. The CPU's nearest rivals are all AMD EPYC server processors, indicating that desktop gaming CPUs with comparable raw compute power are rare. The GPU's nearest rivals include the 4080 SUPER and several AMD cards, showing that the RTX 4080 occupies a well-contested performance segment. The gap between the combo's rank (215th) and the GPU's percentile (86th) suggests that other combinations with similar GPUs but stronger CPUs achieve higher rankings in this game, or that the RTX 4080 is often paired with more powerful processors in the test database.

Settings Recommendations

For the best experience in Microsoft Flight Simulator with this hardware, the data points to the Medium preset as the optimal balance of performance and visual quality. At 1080p Medium, the combo delivers 164 FPS average with a 139 FPS minimum, providing a substantial cushion above the 60 FPS threshold and even above 120 FPS for high-refresh-rate displays. At 1440p Medium, the average drops to 132 FPS with a 112 FPS minimum, still well above 60 FPS and suitable for most gaming monitors. At 4K Medium, the average is 97 FPS with an 83 FPS minimum, which is excellent for flight simulation at Ultra HD resolutions.

The High preset is a viable alternative for users who prioritize visual fidelity over frame rate headroom. At 1080p High, the average is 123 FPS, at 1440p High it is 99 FPS, and at 4K High it drops to 73 FPS. The 4K High result is above 60 FPS but with less margin for complex scenes with dense cloud coverage or detailed airport environments. The Ultra preset offers the highest visual quality but with the lowest frame rates: 117 FPS at 1080p, 95 FPS at 1440p, and 70 FPS at 4K. The difference between High and Ultra is minimal in frame rate terms, with only 3-6 FPS separating them across all resolutions, making Ultra the better choice if the visual enhancements are noticeable to the user.

The Low preset, while delivering the highest frame rates (211 FPS at 1080p, 170 FPS at 1440p, 125 FPS at 4K), sacrifices too much visual detail for a flight simulator where situational awareness and visual immersion are key. The Medium preset's min FPS of 83 at 4K is the most compelling statistic: it guarantees that even in the most demanding moments, the frame rate stays well above the 60 FPS threshold. For users with a 144 Hz monitor at 1440p, the Medium preset's 132 FPS average is close to the refresh rate, and the 112 FPS minimum ensures no significant dips below the refresh window.

The recommendation is clear: use Medium settings for any resolution, with the understanding that 4K Medium provides near-4K Ultra frame rates (97 FPS vs 70 FPS) while 1080p Medium delivers exceptional frame rates for esports-grade smoothness. The High preset is only recommended for users who prefer its specific visual characteristics, as the performance cost over Medium (41 FPS at 1080p, 33 FPS at 1440p, 24 FPS at 4K) is meaningful.
