Microsoft Flight Simulator

# Microsoft Flight Simulator — Intel Core Ultra 9 290K Plus + AMD Radeon RX 7600 XT

This combination of Intel's 24-core Arrow Lake Refresh flagship and AMD's 16 GB RDNA 3 mid-range GPU produces a fundamentally CPU-leaning system in Microsoft Flight Simulator, where frame rates scale more with resolution and settings than with the processor's immense multi-threaded headroom. The measured data reveals a system that can push past 100 FPS at 1080p Low but drops to barely playable territory at 4K Ultra, with the GPU acting as the clear limiting factor at higher resolutions while the CPU's single-core strength carries the lower-resolution results.

Resolution Scaling

The frame rate progression from 1080p to 4K follows a predictable pattern of GPU-bound degradation, but the magnitude of the drop varies significantly by preset. At Low settings, the average FPS falls from 106 at 1920x1080 to 85 at 2560x1440, a 19.8% reduction, and then further to 63 at 3840x2160, representing a 40.6% total loss from the 1080p baseline. This steep decline indicates that even at Low settings, the Radeon RX 7600 XT's rendering throughput becomes the bottleneck as pixel count rises, with the CPU's 5.80 GHz boost clock unable to compensate at higher resolutions.

Medium settings show a similar but slightly shallower curve: 82 FPS at 1080p, 66 FPS at 1440p (a 19.5% drop), and 49 FPS at 4K (a 40.2% total decline). The High preset reveals an interesting anomaly — the drop from 1080p to 1440p is 19.4% (62 to 50 FPS), nearly identical to the Medium and Low curves, but the further drop to 4K High is 26% (50 to 37 FPS), which is steeper than the proportional scaling seen elsewhere. This suggests that High settings introduce additional shading or texture workloads that disproportionately tax the GPU at 4K, where the 16 GB frame buffer and 288.0 GB/s memory bandwidth are pushed harder.

Ultra settings produce the most compressed scaling: 59 FPS at 1080p, 47 FPS at 1440p (a 20.3% drop), and 35 FPS at 4K (a 40.7% total decline). The consistency of the 1080p-to-1440p drops across all presets (roughly 19-20%) points to a uniform resolution scaling penalty, while the 1440p-to-4K transitions show more variance (26% for High versus 23-25% for others). The data implies that this system is well-balanced at 1080p and 1440p for Medium and below, but the 4K results across all settings suggest the RX 7600 XT's 2048 shading units and 64 ROPs simply cannot maintain playable frame rates at the higher pixel counts, regardless of CPU headroom.

GPU Role

The Radeon RX 7600 XT's architectural profile explains much of the scaling behavior observed. With 16 GB of GDDR6 memory on a 128-bit bus delivering 288.0 GB/s bandwidth, the card has ample capacity for Microsoft Flight Simulator's large texture sets and terrain data, but the narrow bus width creates a potential throughput ceiling at higher resolutions. The boost clock of 2755 MHz and game clock of 2470 MHz are respectable for the RDNA 3.0 architecture, yet the 22.57 TFLOPS FP32 compute figure is modest compared to the demands of 4K flight simulation, which relies heavily on continuous geometry and shading calculations.

The GPU's 60th percentile ranking among all GPUs (with an average benchmark score of 17083) places it in the mid-range tier, and its nearest rivals include the NVIDIA GeForce RTX 3070 (0.7% higher average score) and the aging GeForce GTX 690 (0.3% lower). This positioning aligns with the measured FPS results: the card can handle 1080p and 1440p gaming comfortably at Medium settings (82 and 66 FPS respectively), but the 4K Medium result of 49 FPS and 4K High of 37 FPS reveal the GPU's limitations under heavier loads.

The DirectX 12 benchmark score of 65 in PassMark is notably low compared to the DirectX 11 score of 167, which may indicate driver-level inefficiencies in Microsoft Flight Simulator's DX12 path. The Vulkan score of 48366 in Geekbench suggests alternative API paths could potentially yield different results, but the measured data only reflects the game's native rendering. The 16 GB memory capacity is generous for current flight simulation titles, yet the 128-bit bus width means the card cannot exploit that capacity as effectively as wider-bus competitors, contributing to the steep 4K performance cliff observed across all settings.

CPU Role

The Intel Core Ultra 9 290K Plus presents an intriguing counterpoint to the GPU's mid-range performance. With 24 cores and 24 threads (no hyperthreading), this Arrow Lake Refresh processor achieves a Cinebench R23 multi-core score of 51731 and a single-core score of 7303, placing it in the 96th percentile of all CPUs. The 5.80 GHz boost clock is among the highest available, and the 36 MB of shared L3 cache provides substantial on-die storage for flight simulation's complex scenery and aircraft systems.

The CPU's nearest rival data shows it sits marginally above the Core Ultra 9 285K (0.2% higher average benchmark score) and the AMD EPYC 4584PX (1.1% higher), while trailing the EPYC 7F72 by 1.3%. This places the 290K Plus in elite company for synthetic workloads, but the measured game FPS reveals that this CPU horsepower is largely underutilized in Microsoft Flight Simulator at higher resolutions. The 1080p Low result of 106 FPS demonstrates the CPU's capability to feed frames quickly, but the 4K Low result of 63 FPS shows the GPU becoming the bottleneck even at minimal settings.

The PassMark multi-thread score of 60860 and single-thread score of 4823 confirm the CPU's balanced performance profile, but the game's engine appears to favor single-core throughput for flight modeling and physics calculations. The data compression score of 698346 and encryption score of 52563 are indicative of strong general-purpose compute, yet these capabilities do not translate to proportional gains in flight simulation frame rates. The CPU's 125W TDP and dual-channel DDR5 memory support (115.2 GB/s bandwidth) provide sufficient memory throughput for the game's streaming needs, but the measured results suggest that even a 24-core processor cannot overcome the GPU's rendering limitations once resolution increases.

How This Combo Ranks

Among 2996 tested combinations in this benchmark database, this pairing of the Core Ultra 9 290K Plus with the Radeon RX 7600 XT ranks 1872nd, placing it in the 62.5th percentile overall. This ranking is notably lower than what the CPU's 96th percentile standing might suggest, indicating that the GPU is dragging the combination down relative to other tested systems. The data implies that many lower-ranked CPUs paired with stronger GPUs outperform this configuration in Microsoft Flight Simulator, as the game's frame rates are more sensitive to GPU capabilities than CPU compute power.

The ranking disparity between the CPU's individual percentile (96th) and the combo's percentile (62.5th) highlights a significant pairing inefficiency. The 24-core processor's immense multi-threaded capabilities are largely wasted in this game, while the GPU's 60th percentile standing becomes the determining factor for overall performance. This suggests that users seeking higher frame rates in Microsoft Flight Simulator would benefit more from upgrading the GPU than the CPU, as the current combination leaves substantial CPU headroom untapped at all tested resolutions.

The measured FPS data supports this interpretation: even at 1080p Low where the CPU has the most influence, the 106 FPS result is respectable but not exceptional for a processor of this caliber. The 4K Ultra result of 35 FPS is firmly in unplayable territory for most users, and the 4K Medium result of 49 FPS is marginal at best. These results position the combo as a capable 1080p and 1440p performer, but one that struggles to deliver smooth experiences at 4K or even at High/Ultra settings on lower resolutions.

Measured FPS Breakdown

At 1920x1080, the system delivers 106 FPS on Low, 82 FPS on Medium (with a minimum of 70 and maximum of 95), 62 FPS on High, and 59 FPS on Ultra. The 1080p results show a clear staircase pattern where each preset tier costs roughly 20-24 FPS, with the gap between High and Ultra being only 3 FPS — suggesting that the Ultra preset's additional effects are not fully utilizing the GPU's remaining capacity at this resolution.

Moving to 2560x1440, the averages drop to 85 FPS on Low, 66 FPS on Medium (minimum 56, maximum 76), 50 FPS on High, and 47 FPS on Ultra. The 1440p results compress the staircase, with Low-to-Medium costing 19 FPS but High-to-Ultra only 3 FPS. This compression indicates that at 1440p, the GPU is beginning to saturate, and the difference between High and Ultra settings becomes negligible as the renderer hits its throughput ceiling.

At 3840x2160, the system produces 63 FPS on Low, 49 FPS on Medium (minimum 42, maximum 56), 37 FPS on High, and 35 FPS on Ultra. The 4K results show the most dramatic preset-to-preset differences, with Low-to-Medium costing 14 FPS and Medium-to-High costing 12 FPS, but High-to-Ultra only 2 FPS. The narrow gap between High and Ultra at 4K (and at all resolutions) suggests that the Ultra preset's marginal visual improvements come at nearly the same performance cost as High, making Ultra an inefficient choice when frame rates are already constrained.

The minimum FPS data for Medium settings across all resolutions (70 at 1080p, 56 at 1440p, 42 at 4K) provides useful context for frame time consistency. The 4K Medium minimum of 42 FPS means that even the smoother Medium preset experiences dips below 45 FPS, which can be noticeable in a flight simulator where camera panning and terrain loading occur frequently. The maximum FPS values (95 at 1080p, 76 at 1440p, 56 at 4K) indicate that the system can occasionally hit smoother territory, but these peaks are not sustained.

Settings Recommendations

The measured data points to Medium settings as the optimal balance for this combination, particularly at 1440p where the 66 FPS average with a 56 FPS minimum provides a consistently playable experience. At 1080p, Medium's 82 FPS average is smooth, and the 70 FPS minimum ensures minimal stuttering during complex flight scenarios. The jump from Medium to High costs 20 FPS at 1080p (82 to 62) and 16 FPS at 1440p (66 to 50), which is a substantial degradation for relatively modest visual improvements in most flight simulation scenarios.

At 4K, no preset delivers a truly smooth experience — even Low's 63 FPS average is accompanied by the knowledge that Medium drops to 49 FPS and Ultra to 35 FPS. Users with 4K displays should consider Medium (49 FPS) as the only viable option, though the 42 FPS minimum suggests occasional dips below the 45 FPS threshold that many players find acceptable. High and Ultra at 4K (37 and 35 FPS respectively) are virtually indistinguishable in performance terms, making High the better choice if visual fidelity is prioritized, since it costs only 2 FPS versus Ultra.

For 1080p users, Low's 106 FPS is excellent for competitive or high-refresh-rate play, but Medium's 82 FPS offers a better balance of visual quality and performance. The 24 FPS difference between Low and Medium (106 to 82) is significant, but the visual improvements in terrain detail and aircraft textures are typically worth the trade-off in a flight simulator where immersion matters. Ultra at 1080p (59 FPS) provides no meaningful advantage over High (62 FPS) and costs 3 FPS, so High is the preferred choice for maximum visual fidelity at this resolution.

FAQ
