Microsoft Flight Simulator

Microsoft Flight Simulator places unusual demands on a system, and the measured results for the Intel Core Ultra 7 265 paired with the AMD Radeon RX 6650 XT reveal a configuration that is consistently playable but never overwhelming. The data shows a clear hierarchy of performance across resolutions and settings, with the combo landing in the 1902nd position out of 2996 tested combinations. This middle-tier ranking suggests a balanced pairing where neither component completely dominates the other, but the specific frame rate patterns indicate where the bottlenecks truly lie.

Settings Recommendations

The measured data provides a clear picture of which presets deliver the best experience for this specific hardware combination. At 1920x1080, the Low preset achieves an average of 105 FPS, which is the highest frame rate recorded across all tests. This is 44 FPS higher than the High preset’s 61 FPS at the same resolution, representing a massive 72% performance jump. However, the Medium preset at 81 FPS offers a more compelling balance, delivering 20 FPS more than High while maintaining a respectable visual quality that Flight Simulator’s scenery-heavy environments benefit from.

For users prioritizing smoothness over fidelity, the 1080p Low setting is the clear winner, but the frame rate drop from Low to Medium is only 24 FPS, while the drop from Medium to High is another 20 FPS. The Ultra preset at 58 FPS is still playable, but the gap between High and Ultra is just 3 FPS, suggesting diminishing returns that make Ultra a poor choice for this resolution. At 2560x1440, the Medium preset’s 66 FPS average with a minimum of 56 FPS provides the most consistent experience, as the Low preset’s 84 FPS is tempting but sacrifices too much detail for a flight simulator where visual landmarks matter.

The 4K results are more constrained, with the Medium preset delivering 48 FPS and a minimum of 41 FPS, which is the only 4K configuration with recorded minimum and maximum values. This indicates that 4K Medium is the only viable option for a stable experience at that resolution, as High drops to 36 FPS and Ultra falls to 35 FPS, both of which are below the 40 FPS threshold where simulation games typically start feeling sluggish. The recommendation across all resolutions is to favor Medium as the sweet spot, as it consistently offers the best compromise between visual fidelity and frame rate stability, particularly when considering the minimum FPS data that is only available for Medium settings.

FAQ

Q: What is the best resolution to play at with this CPU and GPU combo?

A: The data shows that 1920x1080 with Medium settings provides an average of 81 FPS with a minimum of 69 FPS, which is the most balanced configuration. While 1080p Low reaches 105 FPS, the Medium preset offers significantly better visual quality without sacrificing playability. At 1440p Medium, the average drops to 66 FPS, which is still smooth, but 4K Medium at 48 FPS is the highest resolution that maintains a playable frame rate above 40 FPS.

Q: How does the Ultra preset compare to High across different resolutions?

A: The Ultra preset is consistently slower than High, but the gap narrows at higher resolutions. At 1080p, Ultra averages 58 FPS versus High’s 61 FPS, a 3 FPS difference. At 1440p, Ultra averages 47 FPS versus High’s 49 FPS, also a 2 FPS difference. At 4K, Ultra averages 35 FPS versus High’s 36 FPS, just 1 FPS apart. This suggests that the Ultra preset’s additional effects are not heavily GPU-bound at higher resolutions, making High the more practical choice for maximizing detail.

Q: Is this combo more CPU-limited or GPU-limited in Microsoft Flight Simulator?

A: The frame rate scaling from 1080p to 4K indicates a GPU limitation. At 1080p High, the average is 61 FPS, dropping to 49 FPS at 1440p and 36 FPS at 4K. This 41% reduction from 1080p to 4K shows that the RX 6650 XT is the limiting factor, as the CPU’s performance would not degrade with resolution. The CPU’s 20 cores and 30 MB of L3 cache are more than sufficient for the game’s simulation logic, which is why lower resolutions still hit high frame rates.

Q: What is the minimum FPS like for the Medium preset, and why does it matter?

A: The Medium preset is the only one with recorded minimum FPS values: 69 FPS at 1080p, 56 FPS at 1440p, and 41 FPS at 4K. These minimums are crucial for flight simulation because sudden drops in frame rate can disrupt control inputs during landing approaches or dense scenery areas. The 4K minimum of 41 FPS is close to the edge of playability, while the 1440p minimum of 56 FPS offers more headroom.

Q: How does this combo rank compared to other tested configurations?

A: The combo ranks 1902nd out of 2996 tested combinations, placing it in the 63rd percentile of all tested systems. This is a below-average ranking, but it reflects the GPU’s 65th percentile among all GPUs rather than a CPU bottleneck. The CPU ranks in the 93rd percentile among all CPUs, meaning the GPU is the weaker link in this pairing.

Q: Is the 8 GB VRAM on the RX 6650 XT sufficient for this game?

A: The 8 GB of GDDR6 memory appears adequate for the tested settings, as the frame rates remain stable even at 4K. However, the 128-bit memory bus and 280.3 GB/s bandwidth may be why the Ultra preset shows minimal gains over High, as the GPU’s memory subsystem could be limiting texture streaming at higher detail levels.

GPU Role

The AMD Radeon RX 6650 XT is the primary determinant of frame rates in this configuration, as evidenced by the significant performance scaling across resolutions. With a base clock of 2055 MHz and a boost clock of 2635 MHz, the GPU operates at high frequencies, but its 8 GB VRAM and 128-bit bus width are modest for a game that is known for heavy texture usage. The GPU’s 65th percentile ranking among all GPUs and its average benchmark score of 19765 indicate a mid-range performer, which aligns with the measured FPS numbers.

The 4K results are particularly telling: the GPU manages only 36 FPS at High and 35 FPS at Ultra, showing that it is overwhelmed by the pixel count. The 10.79 TFLOPS of FP32 performance is not sufficient to drive Flight Simulator’s complex rendering at 4K with high detail. However, the 2:1 FP16 ratio of 21.59 TFLOPS suggests the GPU could theoretically handle certain compute tasks faster, but the game’s rasterization demands are what limit performance.

The GPU’s memory configuration of 8 GB GDDR6 at 17.5 Gbps effective provides 280.3 GB/s of bandwidth, which is a constraint at higher resolutions where larger textures are streamed. The measured FPS drops from 1080p Medium’s 81 FPS to 1440p Medium’s 66 FPS and 4K Medium’s 48 FPS follow a consistent pattern that indicates the GPU’s fill rate and memory bandwidth are the limiting factors. The fact that the Ultra preset barely differs from High at all resolutions suggests that the GPU’s 64 ROPs and 128 TMUs are saturated, and additional graphical effects do not scale well.

How This Combo Ranks

The combo’s rank of 1902 out of 2996 tested combinations places it in the lower half of all tested systems, but this ranking must be interpreted carefully. The CPU, Intel Core Ultra 7 265, ranks in the 93rd percentile among all CPUs with an average benchmark score of 64640, and its nearest rivals include the AMD EPYC 4464P with a delta of -0.3% and the Intel Core Ultra 7 265F with a delta of +0.3%. This indicates the CPU is performing exactly as expected for its class.

The GPU, AMD Radeon RX 6650 XT, ranks in the 65th percentile among all GPUs with an average benchmark score of 19765, and its nearest rivals include the NVIDIA Tesla K40m with a delta of -0.6% and the AMD FirePro D300 with a delta of +0.7%. The GPU’s percentile is significantly lower than the CPU’s, which explains why the combo ranks below average. The data suggests that the CPU is not the bottleneck, as its performance is well above the GPU’s. The combo’s overall rank is dragged down by the GPU’s mid-range positioning, meaning that users with a stronger GPU would see much better results with this same CPU.

The deltaPct values for the CPU’s rivals show minimal variation, with the EPYC 4464P being 0.3% slower and the Ultra 7 265F being 0.3% faster. This tight grouping confirms that the CPU’s performance is stable and predictable. For the GPU, the rivals are also closely matched, with the Tesla K40m being 0.6% slower and the FirePro D300 being 0.7% faster. This implies that the RX 6650 XT is a consistent performer within its class, and the combo’s ranking is a direct result of the GPU’s inherent capabilities rather than any unusual system-level issue.

Resolution Scaling

The measured FPS data reveals a clear pattern of resolution scaling that identifies the GPU as the limiting component. At 1080p High, the average is 61 FPS, which drops to 49 FPS at 1440p and 36 FPS at 4K. This represents a 20% reduction from 1080p to 1440p and a further 27% reduction from 1440p to 4K, for a total 41% drop from 1080p to 4K. The scaling is relatively linear, which is typical for a GPU-bound scenario where the number of pixels directly impacts the workload.

The Low preset shows a similar pattern: 105 FPS at 1080p, 84 FPS at 1440p, and 62 FPS at 4K. The percentage drops are 20% and 26%, respectively, which is very close to the High preset’s scaling. This consistency across settings further confirms that the GPU’s pixel throughput is the limiting factor, as the CPU’s workload does not change with resolution. If the CPU were the bottleneck, the frame rates would remain flat across resolutions, but the data shows a steady decline.

The Medium preset, which has the most complete data with minimum and maximum values, shows the same trend: 81 FPS at 1080p (min 69, max 94), 66 FPS at 1440p (min 56, max 75), and 48 FPS at 4K (min 41, max 56). The minimum FPS values also scale proportionally, indicating that the GPU’s performance headroom is consistent. The fact that the 4K Medium minimum of 41 FPS is above the 30 FPS threshold but below the 60 FPS target suggests that users should stick to 1440p for a more comfortable experience.

Measured FPS Breakdown

The full dataset provides a comprehensive view of performance across all tested configurations. At 1920x1080, the Low preset delivers an average of 105 FPS, which is the highest recorded value. The Medium preset averages 81 FPS with a minimum of 69 FPS and a maximum of 94 FPS, offering a stable experience. The High preset drops to 61 FPS, and the Ultra preset is only marginally lower at 58 FPS. This close grouping between High and Ultra at 1080p suggests that the GPU is already near its limits, and the additional Ultra effects have minimal impact.

At 2560x1440, the Low preset averages 84 FPS, which is still quite high, but the Medium preset’s 66 FPS average with a 56 FPS minimum provides a more balanced experience. The High preset averages 49 FPS, and the Ultra preset averages 47 FPS, showing only a 2 FPS difference. This pattern repeats at 4K, where the Low preset averages 62 FPS, Medium averages 48 FPS, High averages 36 FPS, and Ultra averages 35 FPS. The High and Ultra presets are nearly identical at every resolution, which indicates that the GPU’s shading units and texture units are fully utilized at High, and Ultra adds no measurable benefit.

The minimum FPS data is only available for the Medium preset, and it shows a consistent pattern: 69 FPS at 1080p, 56 FPS at 1440p, and 41 FPS at 4K. These minimums are within 15% of the averages, indicating that frame pacing is relatively stable. The maximum FPS values of 94, 75, and 56 FPS at the respective resolutions show that the GPU has some burst capability, but the averages are more representative of sustained performance.

CPU Role

The Intel Core Ultra 7 265 is a high-end processor that ranks in the 93rd percentile among all CPUs, with an average benchmark score of 64640. Its 20 cores and 20 threads, combined with a base clock of 2.40 GHz and a boost clock of 5.30 GHz, provide substantial computational power. 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, which is ample for the game’s simulation logic.

The CPU’s benchmark results are impressive, with a Cinebench R23 multi-core score of 42216 and a single-core score of 5960. The PassMark multi-thread score of 49682 and single-thread score of 4689 further confirm its capabilities. However, in Microsoft Flight Simulator, the CPU’s role is primarily to handle the game’s physics, AI, and world-streaming calculations, which are not heavily dependent on resolution. The measured FPS data shows that the CPU is not a bottleneck, as the frame rates scale with resolution in a way that indicates GPU limitation.

The CPU’s nearest rivals include the AMD EPYC 4464P, which scores 0.3% lower, and the Intel Core Ultra 7 265F, which scores 0.3% higher. These small deltas confirm that the Ultra 7 265 is performing at the expected level for its architecture. The CPU’s 3 nm process node and TSMC foundry suggest efficient power consumption, but the 65 W TDP is modest compared to its performance, indicating that thermal throttling is unlikely to be an issue. The CPU’s memory support for DDR5 with a dual-channel bus and 102.4 GB/s bandwidth provides sufficient data throughput for the game’s streaming needs, further ensuring that the CPU does not limit frame rates.
