Microsoft Flight Simulator

Microsoft Flight Simulator presents one of the most demanding workloads in PC gaming, and the combination of the Intel Core Ultra 7 265 and the NVIDIA GeForce GTX 1650 yields a narrow operating window. The measured data shows a configuration that is heavily constrained by the graphics card, with the processor providing ample headroom that goes largely unused at higher resolutions. This analysis breaks down the measured FPS across resolutions and settings, examines the role of each component, and provides a roadmap for playable experiences.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, clearly identifying the GPU as the limiting factor. At Low settings, the average frame rate falls from 48 FPS at 1920x1080 to 39 FPS at 2560x1440 and then to 29 FPS at 3840x2160. This represents a 19% decline from 1080p to 1440p and a further 26% decline from 1440p to 4K. The scaling pattern shows that the GTX 1650's rendering pipeline saturates quickly as pixel count increases, with the 4K Low result being only 60% of the 1080p Low performance.

The High settings preset shows a similar trajectory but with lower absolute values. The average FPS at 1080p High is 28, dropping to 23 at 1440p and 17 at 4K. The percentage drops are 18% and 26% respectively, mirroring the Low settings pattern. This consistency suggests that the resolution scaling is purely a function of pixel throughput rather than a settings-specific bottleneck. The Ultra preset follows the same shape: 27 FPS at 1080p, 22 FPS at 1440p, and 16 FPS at 4K.

What the data reveals is that the GTX 1650's 4 GB of GDDR5 memory and 128-bit bus are insufficient for the high-resolution textures and geometry that Flight Simulator streams. The gap between 1080p and 4K is not a gradual slope but a cliff, indicating that the GPU runs out of memory bandwidth and shading power simultaneously. For users targeting 4K, even the Low preset at 29 FPS is barely playable, and the Ultra preset at 16 FPS is a slideshow. The measured numbers show that 1080p is the only resolution where the combination approaches acceptable playability, and even then, only at Low or Medium settings.

CPU Role

The Intel Core Ultra 7 265 is a 20-core, 20-thread processor with a base clock of 2.40 GHz and a boost clock of 5.30 GHz. Its benchmark results are strong, with a Cinebench R23 multi-core score of 42216 and a single-core score of 5960. The PassMark single-thread score of 4689 places it in the 93rd percentile of all CPUs, indicating excellent per-core performance. This is critical for Flight Simulator, which is known to be heavily dependent on single-thread performance for its simulation loop and world-building logic.

However, the measured FPS data shows that the CPU is not the bottleneck in this configuration. At 1080p Low, the average FPS is 48, which is higher than any other preset at that resolution but still well below what the CPU could theoretically drive. The Cinebench R15 single-core score of 600 and R20 single-core score of 884 suggest that the Core Ultra 7 265 has enough raw speed to feed a much faster GPU. The fact that FPS drops from 48 at 1080p Low to 29 at 4K Low proves that the GPU is the limiting component, not the processor.

The CPU's 30 MB of shared L3 cache and 3 MB per-core L2 cache help with the massive asset streaming that Flight Simulator performs. The PassMark data compression score of 522983 indicates fast decompression, which is relevant for loading terrain and aircraft data. Yet, in this pairing, the CPU's capabilities are largely latent. The 20 cores do not provide a measurable benefit at these frame rates because the GTX 1650 cannot generate enough frames to stress the processor. The data shows a classic case of overspending on the CPU relative to the GPU, where the processor sits idle waiting for the graphics card to catch up.

Settings Recommendations

Given the measured data, the only playable configuration is at 1920x1080 with Low settings, which produces an average of 48 FPS. This is the only preset across all resolutions that exceeds the 30 FPS threshold generally considered the minimum for a flight simulator, where smooth panning and instrument readability are essential. The Medium preset at 1080p delivers 37 FPS, which is also playable but with a noticeable 23% reduction in frame rate compared to Low. For users who prioritize visual fidelity over smoothness, Medium at 1080p is the best compromise, as it offers a 30% improvement over High's 28 FPS.

At 2560x1440, the Low preset drops to 39 FPS, which is borderline playable but not recommended for precision flying. The Medium preset at 1440p yields 30 FPS, which is the exact threshold but with min FPS of 26, indicating stutter during complex scenes. The 4K resolution is not viable for any preset, with the best result being Low at 29 FPS, which lacks the fluidity needed for landing approaches and weather navigation. The Ultra preset should be avoided entirely, as it produces 16 FPS at 4K and 27 FPS at 1080p, both of which are below playable thresholds.

The data suggests that users should run the game at 1080p Low for maximum playability, or 1080p Medium if they accept occasional frame drops. The High preset at 1080p (28 FPS) is not worth the visual gain over Medium (37 FPS), as the 24% performance penalty outweighs the graphical improvements. For those with 1440p monitors, dropping to 1080p Low is the recommended path rather than accepting 39 FPS at native resolution.

How This Combo Ranks

The Intel Core Ultra 7 265 and NVIDIA GeForce GTX 1650 combination ranks 2885 out of 2996 tested combos for Microsoft Flight Simulator. This places it in the bottom 4% of all tested configurations, which aligns with the measured FPS data showing sub-30 FPS performance at most settings. The rank reflects the severe GPU limitation, as the GTX 1650's PassMark G3D score of 7880 places it in the 40th percentile of all GPUs, and its nearest rivals include the Intel UHD Graphics 750 (7441) and AMD Radeon R7 350 (7425). The GTX 1650 is only 0.3% faster than the AMD Radeon HD 8850M in average benchmark score, which underscores its entry-level positioning.

The CPU's rank is much higher, with an average benchmark score of 64640 and a 93rd percentile standing. Its nearest rivals are the AMD EPYC 4464P (64823, -0.3% delta) and Intel Core Ultra 7 265F (64438, +0.3% delta), showing that the processor is competitive with server-class parts. However, this disparity between CPU and GPU capability creates a bottleneck that the combo rank captures. The 2885th place out of 2996 combos indicates that this pairing is poorly balanced for Flight Simulator, where the GPU demands far more than this card can deliver. The data shows that the combo rank is dragged down entirely by the GPU, as the CPU would rank much higher if paired with a more capable graphics card.

The data shows a maximum spread of 32 FPS between the best case (1080p Low at 48 FPS) and the worst case (4K Ultra at 16 FPS). The Medium preset is the only one with min/max data, showing consistency across resolutions: 19-26 at 4K, 26-35 at 1440p, and 32-43 at 1080p. The Low preset at 1080p is the only configuration that approaches the 60 FPS target, though it still falls short by 12 FPS.

GPU Role

The NVIDIA GeForce GTX 1650 is a Turing-architecture GPU built on a 12 nm process with 896 shading units, 56 texture mapping units, and 32 ROPs. Its base clock is 1485 MHz with a boost of 1665 MHz, and it has 4 GB of GDDR5 memory on a 128-bit bus with 128.1 GB/s bandwidth. The FP32 performance is 2.984 TFLOPS, which is modest by modern standards. The GPU's PassMark G3D score of 7880 places it in the 40th percentile of all GPUs, confirming its entry-level status. Its nearest rival, the Intel Arc A310, is 1% faster, while the AMD Radeon HD 8850M is 0.3% slower.

In Microsoft Flight Simulator, the GPU's limitations are exposed immediately. The 4 GB VRAM is insufficient for High and Ultra textures at 1440p and 4K, leading to the low FPS values measured. The GPU's 128.1 GB/s memory bandwidth is a severe constraint for a game that streams high-resolution satellite imagery and terrain data. The measured FPS at 4K High (17 FPS) and 4K Ultra (16 FPS) are nearly identical, suggesting that the GPU is hitting a hard performance wall regardless of settings. This is likely due to the memory bandwidth ceiling, not the shading rate.

The GTX 1650's DirectX 12 benchmark score of 35 (PassMark) indicates weak API-level performance, which is relevant since Flight Simulator uses DirectX 12. The DirectX 11 score of 58 is higher, suggesting the game might run slightly better in DX11 mode, though this is not tested in the data. The GPU's 75 W TDP and lack of power connectors indicate it is designed for basic systems, not high-end simulation workloads. The data shows that the GTX 1650 is the singular reason this combo ranks 2885th out of 2996, as its performance is simply not adequate for the demands of Flight Simulator at any resolution above 1080p Low.
