# Microsoft Flight Simulator: Intel Core Ultra 5 225 + NVIDIA GeForce RTX 5090

The Intel Core Ultra 5 225 paired with the NVIDIA GeForce RTX 5090 delivers a compelling Microsoft Flight Simulator experience, with the measured data showing this combination ranks 48th out of 2,996 tested combos. The RTX 5090’s massive 32 GB GDDR7 memory and 1.79 TB/s bandwidth provide ample headroom, while the Core Ultra 5 225’s 10 cores and 4.90 GHz boost clock keep the simulation running smoothly across resolutions. The data reveals a system that scales predictably with settings, though the CPU becomes a limiting factor at lower resolutions.

Resolution Scaling

The FPS progression from 1080p to 4K tells a clear story about where the bottleneck lies in this pairing. At 1080p with Low settings, the combo achieves 233 FPS, which drops to 192 FPS at 1440p and further to 142 FPS at 4K. This represents a 39% reduction from 1080p to 4K at Low settings, indicating that even at the lowest graphical preset, the GPU is still being pushed harder as resolution increases. The RTX 5090’s 104.8 TFLOPS FP32 performance is clearly not idle at 1080p, but the scaling suggests the CPU is keeping up well enough to allow the GPU to flex its muscles.

At Medium settings, the pattern continues: 185 FPS at 1080p, 149 FPS at 1440p, and 110 FPS at 4K. The drop from 1080p to 1440p is 19.5%, while 1440p to 4K sees a 26.2% reduction. This steeper decline at higher resolutions points to the GPU becoming more dominant in the rendering pipeline, which is expected given the RTX 5090’s 176 ROPs and 1,636.8 GTexel/s texture rate. The Medium preset also provides the only min/max FPS data in the pack, showing 158-213 FPS at 1080p, 127-172 FPS at 1440p, and 94-127 FPS at 4K, which indicates consistent frame pacing without severe dips.

High settings show a similar trend: 139 FPS at 1080p, 112 FPS at 1440p, and 83 FPS at 4K. The 1080p-to-4K reduction here is 40.3%, nearly identical to Low settings, suggesting that the High preset’s additional graphical load doesn’t disproportionately burden the GPU relative to resolution scaling. Ultra settings, the most demanding preset, yields 133 FPS at 1080p, 107 FPS at 1440p, and 79 FPS at 4K. The 1080p-to-4K drop is 40.6%, again consistent with the other presets.

The key insight from this scaling data is that the RTX 5090 is the primary driver of performance differences across resolutions, but the Intel Core Ultra 5 225 does not become a severe bottleneck even at 1080p. The fact that 1080p Low yields 233 FPS while 1080p Ultra yields 133 FPS (a 42.9% reduction) shows the GPU is still scaling with settings, not being held back by the CPU. However, the relatively modest gains from 1440p to 1080p at Ultra settings (107 to 133 FPS, a 24.3% increase) compared to the 1440p-to-4K drop (107 to 79 FPS, a 26.2% decrease) hints that the CPU’s 20 MB L3 cache and 10 threads are starting to limit frame rates at lower resolutions where GPU load is lighter.

How This Combo Ranks

With a combo rank of 48 out of 2,996 tested combinations, this pairing sits in the top 1.6% of all systems tested in Microsoft Flight Simulator. This is an exceptional result, driven primarily by the RTX 5090’s position in the 92nd percentile of GPUs and the Core Ultra 5 225’s 85th percentile CPU standing. The rank reflects the synergy between these components: the CPU provides enough single-thread performance (Cinebench R23 single-core score of 3,655) to feed the GPU adequately, while the GPU’s massive memory bandwidth handles the high-resolution textures typical of flight simulation.

Compared to other combos in the database, this system outperforms the vast majority of alternatives. The top 1.6% ranking means only 47 other combinations deliver higher average FPS in this game. This is particularly notable because the Core Ultra 5 225 is not a flagship CPU — its 10 cores and 10 threads are modest by modern standards — but the RTX 5090’s brute force compensates. The combo’s performance is especially strong at 4K, where the GPU’s 32 GB memory and 512-bit bus width shine. At 1080p, the CPU becomes more of a factor, but the system still delivers 133 FPS at Ultra, which is more than adequate.

The rank also benefits from the game’s optimization for high-end GPUs. Microsoft Flight Simulator is known for being GPU-intensive at high resolutions, and the RTX 5090’s 104.8 TFLOPS FP32 performance and 170 RT cores handle the rendering load effortlessly. Meanwhile, the CPU’s 3.30 GHz base clock and 4.90 GHz boost clock provide the responsiveness needed for flight physics and AI calculations, though the 20 MB L3 cache is relatively small for a modern CPU.

Settings Recommendations

The measured data provides clear guidance on which settings preset offers the best experience. For 4K displays, the Medium preset at 110 FPS is the sweet spot, as it delivers smooth gameplay with a 94 FPS minimum that never drops below playable thresholds. High at 83 FPS is also viable for those prioritizing visual fidelity, but the 79 FPS at Ultra is close enough to the edge that any complex scenery could cause noticeable dips. The Low preset at 142 FPS at 4K is unnecessary unless the user prioritizes maximum frame rates over visuals.

At 1440p, the High preset at 112 FPS is the recommended choice. It offers a significant visual upgrade over Medium (149 FPS) while maintaining frame rates above 100. Ultra at 107 FPS is nearly as fast and provides the best image quality, making it a strong alternative for users with high-refresh-rate 1440p monitors. The Low preset at 192 FPS is overkill for most displays but could benefit competitive players, though flight simulators rarely demand such high frame rates.

For 1080p, the Ultra preset at 133 FPS is the clear recommendation. It delivers the best visual quality while still exceeding 120 FPS, which is smooth on most monitors. High at 139 FPS offers marginal performance gains with reduced visual fidelity, while Medium at 185 FPS and Low at 233 FPS are only useful for users with 240 Hz displays who prioritize frame rate above all else. Given that the min FPS at 1080p Medium is 158 FPS, even the most demanding scenes will remain fluid.

Overall, the data suggests that the Medium preset provides the best balance of performance and visual quality across all resolutions, with the 4K Medium minimum of 94 FPS being the lowest recorded value in the entire measured set. For users with lower-refresh-rate displays, stepping up to High or Ultra is feasible without dropping below 60 FPS at any resolution.

At 1920x1080, the combo delivers its highest frame rates. Low settings produce 233 FPS average, which is the fastest result in the entire dataset. Medium settings yield 185 FPS with a range of 158 to 213 FPS, showing excellent consistency. High settings average 139 FPS, while Ultra settings drop to 133 FPS. The gap between High and Ultra is only 4.3%, indicating diminishing returns from the Ultra preset at this resolution.

At 2560x1440, performance remains strong. Low settings achieve 192 FPS, a 17.6% reduction from 1080p Low. Medium settings average 149 FPS with a range of 127 to 172 FPS, maintaining the pattern of tight frame pacing. High settings deliver 112 FPS, while Ultra settings reach 107 FPS. The difference between High and Ultra at 1440p is just 4.5%, similar to the 1080p gap, suggesting the Ultra preset’s additional cost is consistent regardless of resolution.

At 3840x2160, the RTX 5090’s capabilities are fully tested. Low settings produce 142 FPS, which is still very high for 4K. Medium settings average 110 FPS with a range of 94 to 127 FPS, providing the most complete data point in the dataset. High settings yield 83 FPS, while Ultra settings average 79 FPS. The 1440p-to-4K drop at Ultra is 26.2%, which is the steepest reduction across all presets, confirming that 4K Ultra is the most demanding configuration tested.

Across all resolutions, the Medium preset consistently offers the best balance, with the largest dataset including min and max FPS values. The 4K Medium data (94-127 FPS) is particularly valuable, as it demonstrates that even at the highest resolution, the combo maintains a minimum above 90 FPS, ensuring a smooth experience in all but the most extreme flight scenarios.

CPU Role

The Intel Core Ultra 5 225 is a 10-core, 10-thread processor based on the Arrow Lake architecture, manufactured on a 3 nm process by TSMC. It operates at a 3.30 GHz base clock and boosts up to 4.90 GHz, with a 65 W TDP that keeps power consumption modest. The CPU’s cache hierarchy includes 192 KB L1 per core, 3 MB L2 per core, and 20 MB shared L3, which is relatively small compared to high-end desktop CPUs but sufficient for this workload.

In Microsoft Flight Simulator, the CPU’s role is primarily to handle simulation logic, AI traffic, and physics calculations, while the GPU renders the world. The measured FPS data shows that the Core Ultra 5 225 is capable of feeding the RTX 5090 effectively at all resolutions, though its limitations become apparent at 1080p. The 233 FPS at 1080p Low suggests the CPU can push frame rates very high, but the scaling from 1080p to 4K at Low (39% reduction) indicates the GPU is still the primary driver of resolution-based performance changes.

The CPU’s benchmark scores provide context for its performance. Its Cinebench R23 multi-core score of 25,891 and single-core score of 3,655 place it solidly in the mid-range, with a PassMark multi-thread score of 30,459 and single-thread score of 4,412. These numbers are competitive with its nearest rivals, including the AMD Ryzen 5 5600F and Ryzen 5 5500X3D, all of which have average scores within 0.5% of each other. The CPU’s 85th percentile ranking among all CPUs confirms it is a solid performer, even if it doesn’t lead the pack.

For Microsoft Flight Simulator specifically, the CPU’s 10 threads are adequate, as the game is not heavily multi-threaded. The lack of hyperthreading means 10 threads are all that’s available, but the high boost clock of 4.90 GHz helps single-threaded tasks like flight model calculations. The 20 MB L3 cache is sufficient for the game’s data access patterns, though larger caches on rival CPUs like the Ryzen 5 5500X3D (which has 3D V-Cache) could theoretically offer better performance in cache-sensitive workloads. However, the measured FPS data shows this CPU keeps up with the RTX 5090 without becoming a significant bottleneck, especially at 1440p and 4K where the GPU dominates.
