# How This Combo Ranks

The Intel Core Ultra 7 265 paired with the NVIDIA GeForce RTX 5090 D achieves a combo rank of 5 out of 2,996 tested combinations in Microsoft Flight Simulator. This places the pairing in the top 0.17% of all tested configurations, a remarkable position that reflects the synergy between a high-core-count Arrow Lake processor and a flagship Blackwell GPU. The rank is based on measured performance across all settings and resolutions, and the data shows this combo sits at the very apex of what is achievable in this flight simulator.

To contextualize this rank, consider that the CPU alone holds a 93rd percentile standing among all processors, while the GPU sits at the 92nd percentile among all graphics cards. When combined, their rank of 5 suggests that the pairing extracts near-maximum performance from both components. The nearest rival CPUs to the Core Ultra 7 265—such as the AMD EPYC 4464P with an average score of 64,823 (delta of -0.3%) and the Intel Core Ultra 7 265F with 64,438 (delta of +0.3%)—show that the processor is competitive within its own tier, though the GPU is clearly the dominant contributor to the overall combo ranking.

The data indicates that this combination is not merely a collection of high-end parts but a carefully matched duo. The 5th-place ranking out of 2,996 combos means only four other configurations deliver higher average frame rates across the measured scenarios. This is notable because Microsoft Flight Simulator is notoriously demanding, with complex scenery rendering and physics calculations that stress both CPU and GPU simultaneously. The fact that this combo ranks so highly suggests balanced performance rather than a bottleneck from either component.

GPU Role

The NVIDIA GeForce RTX 5090 D is the centerpiece of this configuration, and its specifications align closely with the frame rates observed. The GPU features 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of memory bandwidth. This is critical for Microsoft Flight Simulator, which streams vast amounts of terrain and texture data. The 32 GB capacity ensures that even at 4K resolution with high-detail settings, the GPU never runs out of memory, allowing the simulator to cache more scenery tiles without stutter.

Clock speeds for the RTX 5090 D are a base of 2017 MHz and a boost of 2407 MHz, with memory running at 1750 MHz (28 Gbps effective). These clocks, combined with 21,760 shading units and 170 RT cores, provide the raw compute needed for the simulator's lighting and shadow calculations. The GPU's FP32 throughput of 104.8 TFLOPS is particularly relevant because Microsoft Flight Simulator relies heavily on traditional rasterization for its ground and cloud rendering. The pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s further underscore the GPU's capacity to fill frames at high resolutions.

In the measured data, the GPU's role becomes evident when examining the FPS scaling across settings. At 4K Ultra, the combo delivers 84 FPS, while at 4K Low it reaches 151 FPS—a difference of 67 FPS that reflects the GPU's ability to handle increased shader complexity. The RTX 5090 D's percentile of 92 among all GPUs, with an average benchmark score of 77,712, places it among the elite, and the nearest rivals (AMD Radeon RX 6650M XT at 76,904, delta +1.1%; AMD Radeon RX 6850M XT at 78,940, delta -1.6%) show that even small performance differences are significant at this tier.

Settings Recommendations

Based on the measured FPS rows, the optimal settings balance depends on the target refresh rate and resolution. For 1080p displays, the Medium preset yields an average of 198 FPS with a minimum of 168 FPS and maximum of 227 FPS. This is the sweet spot for high-refresh monitors, as it stays well above 144 FPS while maintaining visual quality. The Ultra preset at 1080p drops to 142 FPS average, which is still playable but sacrifices the smoothness margin that Medium provides.

At 1440p, the Medium preset delivers 159 FPS average (min 136, max 183), which is excellent for 144 Hz displays. High settings at 1440p achieve 120 FPS, and Ultra drops to 114 FPS. For users prioritizing visual fidelity over raw frame rates, High at 1440p offers a strong compromise, maintaining triple-digit FPS while enabling more advanced effects. The Low preset at 1440p reaches 205 FPS, which is only useful for competitive scenarios—uncommon in a flight simulator.

For 4K, the data shows that Medium is the most balanced choice, delivering 118 FPS average (min 100, max 135). This stays above the 100 FPS threshold, which is impressive for 4K in this simulator. High at 4K yields 88 FPS, and Ultra drops to 84 FPS, both of which are playable but may feel less smooth on high-refresh 4K panels. The Low preset at 4K achieves 151 FPS, which is unnecessary for most users given the visual compromises. The recommendation is to use Medium at 4K and 1440p, and Medium or High at 1080p depending on refresh rate priorities.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four settings levels, providing a comprehensive view of performance. At 1920x1080, the combo delivers 248 FPS on Low, 198 FPS on Medium (min 168, max 227), 149 FPS on High, and 142 FPS on Ultra. The gap between Low and Ultra is 106 FPS, indicating that the GPU scales well with settings but that the CPU becomes a factor at lower settings where the frame rate approaches 250 FPS.

At 2560x1440, the results are 205 FPS on Low, 159 FPS on Medium (min 136, max 183), 120 FPS on High, and 114 FPS on Ultra. The drop from Low to Ultra is 91 FPS. Notably, the difference between High and Ultra at 1440p is only 6 FPS, suggesting diminishing returns from the highest preset. The Medium preset's minimum of 136 FPS ensures smooth gameplay even in complex scenery areas.

At 3840x2160, the data shows 151 FPS on Low, 118 FPS on Medium (min 100, max 135), 88 FPS on High, and 84 FPS on Ultra. The 4K resolution imposes significant load on the GPU, with the gap between Low and Ultra reaching 67 FPS. The Medium preset's minimum of 100 FPS is a key threshold, ensuring frame times stay consistent. The Ultra preset at 4K, at 84 FPS, represents the most demanding scenario tested, and the fact that it stays above 80 FPS underscores the GPU's capability.

CPU Role

The Intel Core Ultra 7 265 is a 20-core, 20-thread processor based on the Arrow Lake architecture, manufactured on a 3 nm process by TSMC. It has a base clock of 2.40 GHz and a boost clock of 5.30 GHz, with a TDP of 65 W. The CPU's cache configuration includes 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3 cache. This large cache hierarchy is beneficial for Microsoft Flight Simulator, which frequently accesses terrain and aircraft data.

In benchmark tests, the CPU achieves a Cinebench R23 multicore score of 42,216 and a single-core score of 5,960. The PassMark multithread score is 49,682, and the single-thread score is 4,689. These numbers indicate strong multi-threaded performance, which matters for the simulator's physics and AI calculations, as well as solid single-thread performance for the main rendering loop. The CPU's percentile of 93 among all processors places it in the top tier, though its average benchmark score of 64,640 is nearly identical to its nearest rivals: the AMD EPYC 4464P (64,823, delta -0.3%) and the Intel Core Ultra 7 265F (64,438, delta +0.3%).

The CPU's role in this combo is to feed the GPU with enough data to maintain high frame rates. The data shows that at 1080p Low, the combo hits 248 FPS, which is a scenario where the CPU is more likely to be the limiting factor. The 20 cores and 20 threads ensure that the simulator's background threads for weather, traffic, and scenery streaming do not starve the main render thread. The CPU's memory bandwidth of 102.4 GB/s over a dual-channel DDR5 interface is adequate for the simulator's data demands, though the GPU's 1.79 TB/s bandwidth is clearly the more critical path for high-resolution textures.

Resolution Scaling

The FPS data across resolutions reveals how the bottleneck shifts between CPU and GPU. From 1080p to 1440p, the average FPS across all settings drops by roughly 20-25%. For example, at Medium settings, 1080p yields 198 FPS, while 1440p yields 159 FPS—a 19.7% reduction. From 1440p to 4K at Medium, the drop is more severe: 159 FPS to 118 FPS, a 25.8% reduction. This pattern indicates that the GPU becomes increasingly dominant as resolution increases, which is expected given the pixel count quadruples from 1080p to 4K.

At Low settings, the scaling is even more pronounced: 248 FPS at 1080p, 205 FPS at 1440p, and 151 FPS at 4K. The 1080p to 4K drop of 97 FPS (39.1%) demonstrates that even at minimal graphical load, the GPU is still the primary constraint. However, the fact that 1080p Low exceeds 240 FPS suggests that the CPU is capable of driving frame rates well beyond typical display refresh rates, meaning the processor is not a bottleneck in most real-world scenarios.

The scaling from High to Ultra settings shows a different trend. At 1080p, High yields 149 FPS and Ultra yields 142 FPS—a mere 4.7% difference. At 4K, High yields 88 FPS and Ultra yields 84 FPS—a 4.5% difference. This consistency across resolutions suggests that the Ultra preset adds only marginal visual improvements beyond High, while the performance cost is minimal. The limiting component at Ultra settings is the GPU, as evidenced by the larger gaps between Low and Medium settings (e.g., 248 to 198 FPS at 1080p, a 20.2% drop) compared to the smaller gaps between High and Ultra.

Overall, the resolution scaling analysis indicates that the RTX 5090 D is the primary performance driver across all tested scenarios. The CPU's 20 cores and high boost clock provide sufficient headroom to avoid bottlenecking, even at 1080p Low where frame rates approach 250 FPS. For users seeking to maximize visual fidelity, the data suggests that 4K Medium is the most efficient combination of quality and performance, while 1080p Medium offers the best balance for high-refresh displays.
