Microsoft Flight Simulator

Resolution Scaling

The measured frame rates for Microsoft Flight Simulator with the AMD Ryzen 7 5800X and NVIDIA GeForce GTX 1650 show a steep and consistent decline as resolution increases, a pattern that clearly identifies the GTX 1650 as the primary bottleneck in this pairing. At 1920x1080 with Low settings, the combo produces an average of 50.5 FPS, which drops to 35.8 FPS at 2560x1440 (–29%) and further to 27.7 FPS at 3840x2160 (–45% from 1080p). This scaling is not linear; the pixel count from 1080p to 1440p increases by 78%, yet the frame rate drops by only 29%, suggesting that the CPU's 8-core, 16-thread configuration is still providing enough headroom at lower resolutions to partially mask the GPU's limitations.

The gap widens dramatically when moving from 1440p to 4K. At 1440p Low, the system delivers 35.8 FPS, but at 4K Low, it falls to 27.7 FPS, a 23% reduction for a 125% increase in pixel count. This disproportionate drop indicates that the GTX 1650's 4 GB of GDDR5 memory and 128-bit bus are being saturated at higher resolutions, with the 128.1 GB/s bandwidth proving insufficient for the texture streaming demands of a flight simulator that renders vast landscapes. The data shows that at 4K, even the Low preset (27.7 FPS) cannot maintain playable smoothness, while the Ultra preset at 4K collapses to 16.6 FPS, which is below the threshold for any reasonable interactive experience.

The pattern across all settings confirms this analysis. At 1080p, the spread between Low (50.5 FPS) and Ultra (29.8 FPS) is 20.7 FPS, showing that the GPU has some headroom to accommodate higher quality settings. At 1440p, that spread narrows to 12.9 FPS (35.8 to 22.9), and at 4K, it narrows further to 11.1 FPS (27.7 to 16.6). The shrinking delta between settings as resolution increases is a classic sign of pixel-bound performance, where the GPU's rendering throughput, not the game's settings complexity, becomes the limiting factor. The Ryzen 7 5800X, with its 3.80 GHz base and 4.70 GHz boost clocks, is clearly not the constraint here; its single-thread performance in Cinebench R23 (3327 points) is ample for flight simulation's largely single-threaded physics and AI workloads.

FAQ

Q: What is the highest average frame rate achievable with this CPU-GPU combo in Microsoft Flight Simulator?

A: The highest measured average is 50.5 FPS, achieved at 1920x1080 with Low settings. No other resolution or settings combination exceeds this figure in the measured data.

Q: Is this system capable of 4K gaming in Microsoft Flight Simulator?

A: The data indicates no. At 3840x2160, even the Low preset only reaches 27.7 FPS, and the Ultra preset drops to 16.6 FPS. Both are below the 30 FPS threshold typically considered minimally playable for a flight simulator.

Q: How does the GTX 1650's performance compare to its nearest rivals in this game?

A: The GPU's average benchmark score is 8713, placing it 0.4% behind the NVIDIA GeForce RTX 3050 A Mobile (8746) and 0.4% behind the AMD Radeon 550X (8749). It sits 0.5% ahead of the NVIDIA Quadro P2200 (8671) and 0.5% behind the AMD Radeon Pro WX 5100 (8761). These deltas are negligible, meaning the GTX 1650 performs essentially on par with its immediate competitors.

Q: What is the best settings-to-performance balance at 1080p for this combo?

A: The data shows that Low settings (50.5 FPS) provide the smoothest experience, but Medium (38.5 FPS) and High (30.8 FPS) are also viable. Ultra (29.8 FPS) sits just below the 30 FPS mark, so High settings offer the best compromise between visual quality and playability.

Q: Does the Ryzen 7 5800X's multi-threading capability help in this game?

A: The CPU's 8-core, 16-thread configuration yields a Cinebench R23 multicore score of 23571, but the game's frame rates are primarily GPU-limited. The 3dmark 16-thread score of 7586 shows strong multi-threaded potential, yet the measured FPS at 4K Ultra (16.6 FPS) suggests the GPU is the constraining element, not the CPU's thread count.

Q: How does this combo rank among all tested configurations for this game?

A: The combo ranks 1715 out of 1795 tested combinations, placing it in the bottom 5% of all configurations. This low ranking is consistent with the GTX 1650's 43rd percentile standing among all GPUs, despite the CPU's 84th percentile ranking.

CPU Role

The AMD Ryzen 7 5800X is a Zen 3 (Vermeer) architecture processor on the AMD Socket AM4 platform, built on a 7 nm process with 4,150 million transistors. Its 8 cores and 16 threads operate at a base clock of 3.80 GHz and a boost clock of 4.70 GHz, with a TDP of 105 W. The CPU's cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of shared L3 cache, which is critical for gaming workloads that benefit from fast access to frequently used data.

In Microsoft Flight Simulator, the CPU's role is to handle flight physics, weather simulation, and AI traffic, tasks that are typically single-threaded or lightly threaded. The 5800X's single-core performance is strong, as evidenced by its Cinebench R23 single-core score of 3327 and Geekbench single-core score of 2194. The 3dmark single-thread score of 943 further confirms this capability. However, the game also scales with multiple threads, and the CPU's 3dmark 8-thread score of 6035 and 16-thread score of 7586 show that it can handle multi-threaded workloads when needed.

The benchmark data reveals that the CPU is never the limiting factor in this combo. At 1080p Low, the system achieves 50.5 FPS, which is a respectable frame rate for a flight simulator, but the GPU's pixel throughput caps performance at higher resolutions. The CPU's percentile ranking of 84 among all CPUs places it well above the GPU's 43rd percentile, indicating a significant performance imbalance. The nearest CPU rivals—the AMD Ryzen 7 5800 (0.3% faster), AMD Ryzen 5 8500GE (0.4% slower), Intel Core i7-13700H (0.4% slower), and Intel Core i5-12600KF (0.8% slower)—are all within 1% of the 5800X's average benchmark score of 27606, meaning the CPU's performance is not a differentiator in this game.

How This Combo Ranks

The AMD Ryzen 7 5800X and NVIDIA GeForce GTX 1650 combination ranks 1715 out of 1795 tested combos for Microsoft Flight Simulator, placing it in the bottom 5% of all configurations. This low ranking is driven almost entirely by the GPU's limited capabilities. The CPU is in the top 16% of all processors (84th percentile), but the GPU is in the bottom half (43rd percentile), creating a severe bottleneck that caps the system's overall performance.

The ranking suggests that this combo is suitable for low-resolution, low-settings gaming in Microsoft Flight Simulator, but it will struggle at higher resolutions. The measured FPS data confirms this: only at 1080p Low (50.5 FPS) and 1080p Medium (38.5 FPS) does the system achieve frame rates that are comfortably playable. At 1440p, the best result is 35.8 FPS on Low settings, which is borderline. At 4K, all settings yield average frame rates below 28 FPS, making the experience choppy and potentially unplayable for most users.

The ranking also reflects the GPU's position relative to its rivals. The GTX 1650's average benchmark score of 8713 is within 0.5% of all four nearest competitors, meaning that swapping to any of these GPUs would yield nearly identical performance in this game. The CPU's rivals are similarly clustered within 0.8% of the 5800X's score. This tight clustering suggests that the combo's rank is more a function of the GPU tier than any specific component choice, and users seeking better frame rates would need to move to a significantly more powerful GPU rather than tweaking within this performance class.

GPU Role

The NVIDIA GeForce GTX 1650 is based on the Turing architecture (TU117 chip) and is manufactured on a 12 nm process with 4,700 million transistors. Its 896 shading units, 56 texture mapping units, and 32 ROPs operate at a base clock of 1485 MHz and a boost clock of 1665 MHz. The GPU has 4 GB of GDDR5 memory on a 128-bit bus, providing 128.1 GB/s of bandwidth. This memory configuration is the most significant limitation for Microsoft Flight Simulator, a game known for streaming large textures and terrain data.

The GPU's compute capabilities are modest: 2.984 TFLOPS of FP32 performance and a pixel rate of 53.28 GPixel/s. In synthetic benchmarks, the GTX 1650 scores 7880 in Passmark G3D and 305 in 3DMark Steel Nomad DX12, placing it in the 43rd percentile of all GPUs. Its nearest rivals—the RTX 3050 A Mobile, Radeon 550X, Quadro P2200, and Radeon Pro WX 5100—are all within 0.5% of its average score of 8713, confirming that the GTX 1650 sits at the very bottom of the discrete GPU performance ladder.

In Microsoft Flight Simulator, the GPU's role is to render the complex 3D scenery, including terrain, buildings, clouds, and lighting effects. The measured FPS data shows that the GPU's 4 GB VRAM is a critical constraint. At 1080p, the game can fit more of its textures into the 128.1 GB/s bandwidth, allowing for 50.5 FPS on Low. But at 4K, the texture data exceeds what the GPU can efficiently process, causing frame rates to plummet to 27.7 FPS on Low and 16.6 FPS on Ultra. The GPU's 75 W TDP and lack of power connectors indicate it is designed for low-power systems, further limiting its performance ceiling in demanding titles like this one.

Measured FPS Breakdown

The measured FPS data provides a comprehensive picture of this combo's performance across three resolutions and four settings levels. At 1920x1080, the system achieves 50.5 FPS on Low, 38.5 FPS on Medium, 30.8 FPS on High, and 29.8 FPS on Ultra. The 1080p Low result is the only configuration that exceeds 50 FPS, and it is the only setting at any resolution that reaches this threshold. The 1080p Medium and High results are playable, but the Ultra preset falls just below 30 FPS, indicating that the GPU cannot maintain smooth performance at maximum settings even at the lowest resolution.

At 2560x1440, the frame rates drop to 35.8 FPS on Low, 31.6 FPS on Medium, 22.9 FPS on Ultra, and 20.1 FPS on High. Notably, the 1440p High result (20.1 FPS) is lower than the 1440p Ultra result (22.9 FPS), which is counterintuitive but may reflect scene complexity variations in the benchmark runs. The 1440p Low result is the only one that breaches 30 FPS, and it does so by a narrow margin.

At 3840x2160, the situation is dire: 27.7 FPS on Low, 21.9 FPS on Medium, 16.6 FPS on Ultra, and 14.2 FPS on High. The 4K results show a compression of the settings range, with only 13.5 FPS separating Low from Ultra. This compression indicates that the GPU is entirely pixel-bound at this resolution, and settings changes have diminishing returns. Across all resolutions, the data shows that the GTX 1650 can handle Microsoft Flight Simulator only at 1080p with reduced settings, and even then, the frame rates are not high, with the best case being 50.5 FPS on Low. Users with this combo should target 1080p resolution and prioritize frame rate over visual fidelity to achieve a playable experience.
