Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding title that stresses both the CPU and GPU heavily, and the measured data for the AMD Ryzen 5 5500 and AMD Radeon RX 6650 XT combination reveals a system that is carefully balanced, though with clear performance ceilings at higher resolutions. The benchmark results across three resolutions and four quality presets show that this pairing is capable of smooth gameplay at 1080p and 1440p, but requires settings adjustments to maintain playable frame rates at 4K.

Resolution Scaling

The frame rate data shows a predictable and steep decline as resolution increases, which is typical for a flight simulator where the visual load on the GPU scales dramatically with pixel count. At 1080p with Low settings, the combo achieves an average of 102.7 FPS, which drops to 84.2 FPS at 1440p and further down to 60.5 FPS at 4K. This represents a 41% reduction in performance from 1080p to 4K at the Low preset, indicating that the GPU is becoming the primary limiting factor as resolution climbs.

The gap between 1080p and 1440p is relatively modest across most settings, suggesting that the CPU has enough headroom to feed the GPU adequately at these resolutions. For instance, at High settings, the frame rate drops from 61.9 FPS at 1080p to 50.7 FPS at 1440p, a decrease of roughly 18%. However, the transition from 1440p to 4K is more punishing, with the High preset falling from 50.7 FPS to 35 FPS, a 31% drop. This steeper decline at 4K confirms that the RX 6650 XT's 8 GB of VRAM and 128-bit memory bus are being saturated, and the GPU's compute resources are struggling to keep up with the increased pixel workload.

Interestingly, the scaling pattern is not uniform across all presets. At Ultra settings, the frame rates are 57.1 FPS at 1080p, 48.1 FPS at 1440p, and 35.3 FPS at 4K. The 1080p to 1440p drop is only 15.8%, which is smaller than the drop seen at High settings. This suggests that at Ultra, the CPU is starting to become a bottleneck even at 1080p, as the Ryzen 5 5500's six cores and twelve threads are fully engaged by the simulation's complex physics and AI calculations. The result is that the GPU has less headroom to show its scaling potential at lower resolutions, and the CPU limitation becomes more apparent as the settings increase.

At 4K, the differences between presets compress significantly. The Low preset manages 60.5 FPS, while Medium drops to 48.1 FPS, High to 35 FPS, and Ultra to 35.3 FPS. The near-identical performance between High and Ultra at 4K is a clear indicator that the GPU is completely maxed out, and any additional graphical fidelity from the Ultra preset does not translate into a measurable frame rate penalty because the hardware is already at its limit. The data suggests that for 4K gameplay, users should target Low or Medium settings to stay above 48 FPS, as the GPU cannot sustain higher presets at playable frame rates.

GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2.0 architecture with a Navi 23 chip, and its specifications directly explain the observed performance patterns. The GPU operates with a base clock of 2055 MHz and a boost clock of 2635 MHz, with a game clock of 2410 MHz. These high clock speeds are crucial for maintaining frame rates in a title like Microsoft Flight Simulator, which relies heavily on sustained GPU throughput rather than burst performance. The 8 GB of GDDR6 memory on a 128-bit bus provides a bandwidth of 280.3 GB/s, which is adequate for 1080p and 1440p but becomes a limiting factor at 4K where the texture and geometry data exceed what the memory subsystem can efficiently deliver.

The GPU's 2048 shading units, 128 texture mapping units, and 64 render output units are configured to deliver a peak pixel rate of 168.6 GPixel/s and a texture rate of 337.3 GTexel/s. These figures translate into the observed frame rates: at 1080p Low, the GPU is nowhere near its limits, allowing the CPU to push the frame rate to 102.7 FPS. However, at 4K Ultra, the pixel rate requirement becomes immense, and the GPU's compute capacity, rated at 10.79 TFLOPS for FP32 operations, is fully utilized, resulting in the 35.3 FPS average.

The benchmark data shows that the GPU's performance relative to its rivals is closely matched. The RX 6650 XT has an average benchmark score of 29024, sitting at the 72nd percentile of all GPUs. Its nearest rival, the AMD Radeon RX 6800M, scores 29011 with a deltaPct of 0, meaning they are statistically identical in overall performance. This parity in synthetic benchmarks, however, does not fully capture the RX 6650 XT's behavior in a simulation-heavy title, where the CPU interaction is more pronounced. The GPU's 32 ray accelerators and support for DirectX 12 Ultimate suggest it is well-equipped for modern rendering techniques, but the measured FPS data indicates that raw rasterization performance is what matters most in this specific game.

The VRAM capacity of 8 GB is worth noting. At 4K with High settings, the game likely approaches this limit, which could cause texture streaming issues and frame time spikes, although the average FPS of 35 suggests the GPU is still managing. The fact that the 4K Ultra frame rate (35.3 FPS) is nearly identical to the 4K High frame rate (35 FPS) implies that the game is not exceeding the VRAM limit at either setting, and the bottleneck is purely computational rather than memory capacity. This is a positive sign for owners of this GPU, as it means the card is not being artificially held back by memory constraints in this title.

Settings Recommendations

Based on the measured FPS data, the optimal preset for this combination depends heavily on the target resolution and the user's preference for visual fidelity versus smoothness. At 1080p, the Medium preset delivers 83.1 FPS, which is significantly higher than the 61.9 FPS of the High preset. The jump from Medium to High costs 21.2 FPS, a 25.5% reduction, which is a substantial penalty for what is likely a modest visual improvement in a game where the scenery is already detailed at Medium. For users with a 60 Hz monitor, the Ultra preset at 57.1 FPS is just below the refresh rate threshold, so Medium or High would be the better choice to ensure a consistent frame rate without dips.

At 1440p, the situation becomes more nuanced. The Low preset achieves 84.2 FPS, which is excellent for a flight simulator, but the Medium preset at 64.7 FPS is still very playable and offers a better visual experience. The High preset at 50.7 FPS is the edge of smoothness, and the Ultra preset at 48.1 FPS is borderline. Given that the difference between High and Ultra at 1440p is only 2.6 FPS, there is little reason to choose Ultra over High unless the user prioritizes maximum graphical detail over a few frames per second. The recommended setting at 1440p is Medium, as it provides a good balance of visual quality and performance, keeping the frame rate comfortably above 60 FPS.

For 4K, the GPU is clearly the limiting factor, and the data shows that only the Low preset, at 60.5 FPS, can consistently maintain a smooth experience. The Medium preset at 48.1 FPS is playable but may feel slightly less fluid, and both High and Ultra at 35 FPS are generally considered too low for a game that requires precise control and situational awareness. The recommendation for 4K is to use the Low preset, as the visual difference between Low and Medium at this resolution is less noticeable due to the high pixel density, and the frame rate improvement from 48.1 to 60.5 FPS is substantial. Users who prioritize visuals over frame rate could opt for Medium, but they should be prepared for occasional stutters.
