Microsoft Flight Simulator

Microsoft Flight Simulator is notoriously demanding, and this pairing of an AMD Ryzen 5 2600 with an AMD Radeon RX 6650 XT produces a wide spread of results depending on how you configure it. The data shows a system that can handle the sim at playable framerates, but requires careful attention to both resolution and quality settings to avoid dipping into stutter territory. The measured frames per second (FPS) across twelve different settings and resolution combinations reveal a clear hierarchy of performance, with the gap between Low and Ultra being substantial at every resolution.

Resolution Scaling

The performance drop from 1080p to 4K is significant and reveals a system that is heavily taxed at higher resolutions. At 1080p with Low settings, the combo achieves an average of 106.2 FPS, which is a very fluid experience for a flight simulator. Moving to 1440p at the same Low preset drops that to 81.7 FPS, a reduction of roughly 23%. At 4K Low, the average falls further to 60.4 FPS, which is still playable but shows the GPU is working much harder as the pixel count increases.

The scaling becomes more punishing at higher quality presets. With High settings, the system produces 60.3 FPS at 1080p, which drops to 49 FPS at 1440p and then to 37.4 FPS at 4K. This pattern indicates that the RX 6650 XT is the primary limiting factor at 1440p and 4K, as the framerate drops almost linearly with the increase in resolution. The jump from 1080p to 1440p at High settings costs about 19% of the performance, while moving from 1440p to 4K at High costs another 24%. The Ultra preset shows the same trend, with 58.9 FPS at 1080p, 47.5 FPS at 1440p, and a marginal 31.8 FPS at 4K. The 4K Ultra result is the only truly unplayable scenario in the entire dataset, suggesting that the combination of the GPU's 8 GB memory capacity and its compute power is insufficient for the highest visual fidelity at that resolution.

Settings Recommendations

The measured rows make it clear that the "Ultra" preset is generally not worth the performance cost for this hardware combination. At 1080p, Ultra yields 58.9 FPS, which is only 1.4 FPS lower than the 60.3 FPS seen at High settings. That is a negligible difference in actual gameplay, but the visual upgrade from High to Ultra is often subtle in this simulator. At 1440p, the gap widens slightly, with Ultra delivering 47.5 FPS versus High's 49 FPS, but both are on the edge of smoothness. At 4K, Ultra drops to 31.8 FPS, which is a slideshow for a sim that requires precise control.

The best experience per the data is the High preset at 1080p, delivering 60.3 FPS. This hits the 60 FPS target that most users consider the baseline for a smooth experience. If you have a 1440p monitor, the Medium preset at 62.6 FPS is the better choice than High at 49 FPS, as it maintains a more consistent framerate that is closer to the 60 FPS mark. For 4K displays, the Low preset at 60.4 FPS is the only option that provides a playable framerate, but it comes with a significant visual compromise. The Medium preset at 4K (47.7 FPS) is a reasonable middle ground if you can tolerate a slightly lower framerate, but it is still below the 60 FPS ideal.

GPU Role

The AMD Radeon RX 6650 XT, with its 8 GB of GDDR6 memory on a 128-bit bus providing 280.3 GB/s of bandwidth, is the clear bottleneck in this pairing at higher resolutions. The data supports this: the 4K High result of 37.4 FPS is a 38% drop from the 1080p High result of 60.3 FPS, which is a steep penalty that points to the GPU running out of memory bandwidth or capacity. The card's boost clock of 2635 MHz and game clock of 2410 MHz are high, but they are not enough to overcome the sheer fill rate demands of 4K in Microsoft Flight Simulator.

The GPU's performance relative to its peers is tight, as it sits in the 72nd percentile of all GPUs. Its nearest rival, the AMD Radeon RX 6800M, has an average score that is essentially identical (0% delta), while the Intel Arc A370M is 0.5% slower and the AMD Radeon RX Vega M GH is 0.6% slower. This indicates that the RX 6650 XT is well-positioned in its performance class, but it is not a high-end part. The 8 GB memory capacity is also a concern for this game, as the high-resolution textures in Microsoft Flight Simulator can easily exceed that limit, forcing the card to swap data more frequently and causing the framerate to tank.

FAQ

Q: Can this combo run Microsoft Flight Simulator at 4K?

A: Yes, but only at Low settings, where it averages 60.4 FPS. At Medium it drops to 47.7 FPS, and at High it falls to 37.4 FPS. Ultra is not viable at 31.8 FPS.

Q: What is the best resolution for a smooth experience?

A: 1080p is the sweet spot. The High preset delivers 60.3 FPS, and even Ultra reaches 58.9 FPS. At 1440p, you must drop to Medium to get above 60 FPS, which nets 62.6 FPS.

Q: How much of a performance gap is there between Low and Ultra at 1440p?

A: The gap is substantial. Low averages 81.7 FPS, while Ultra averages 47.5 FPS. That is a 34.2 FPS difference, or a 42% reduction in performance when maxing out the settings.

Q: Is the CPU or GPU more limiting in this game?

A: The GPU is the limiting factor at higher resolutions. The framerate drops significantly as resolution increases, which is characteristic of a GPU-bound scenario. The CPU's impact is more evident at lower resolutions and settings.

Q: What is the performance percentile of this GPU in the database?

A: The AMD Radeon RX 6650 XT sits in the 72nd percentile of all GPUs, indicating it performs better than the majority of cards but is not a top-tier part.

Q: How does the RX 6650 XT compare to its closest rival?

A: The data shows the AMD Radeon RX 6800M is a 0% delta in average score, meaning they are effectively tied. The Intel Arc A370M is 0.5% slower, and the AMD Radeon RX Vega M GH is 0.6% slower.

How This Combo Ranks

In the broader database of tested combinations, this pairing of the Ryzen 5 2600 and RX 6650 XT ranks 1173 out of 1795 combos for this game. That places it in the lower third of all tested systems, which is a direct reflection of the hardware's age and mid-range positioning. The CPU is an older 2000-series part that sits in the 77th percentile of all CPUs, while the GPU is a more recent but still mid-range card in the 72nd percentile. This rank means that while the combo is fully capable of playing the game, a large number of other configurations will deliver higher average framerates, particularly at 1440p and 4K.

The rank of 1173 out of 1795 suggests that this is a workable but not impressive setup for this specific title. It is not a configuration you would choose for high-refresh-rate competitive play, but it can be tuned to deliver a stable experience at 1080p. The fact that it is ranked just above the 65th percentile of all combos indicates that there is significant headroom for improvement with either a stronger CPU or GPU, but as it stands, the system is balanced enough to avoid being a complete bottleneck at 1080p.

CPU Role

The AMD Ryzen 5 2600 is a 6-core, 12-thread processor based on the Zen+ architecture, with a base clock of 3.40 GHz and a boost clock of 3.90 GHz. It has 16 MB of shared L3 cache and supports dual-channel DDR4 memory with a bandwidth of 46.9 GB/s. In this game, the CPU's role is less prominent than the GPU's, but it still sets the floor for performance. At 1080p Low, the system hits 106.2 FPS, which suggests the CPU is capable of feeding the GPU enough data to reach high framerates. However, as the resolution increases, the framerate drops, indicating that the CPU is not the limiting factor at 1440p or 4K.

The CPU's benchmark scores show it is a competent mid-range part. Its Cinebench R23 multi-core score is 11186, and its single-core score is 1579, which is modest by modern standards. The PassMark multithread score of 13160 and single-thread score of 2239 further confirm this. Compared to its nearest rivals, the Intel Core i5-1345U is 0.4% slower in average score, while the AMD Ryzen 5 7530U is 0.6% faster. This means the 2600 is still competitive with much newer laptop parts, but it lacks the single-thread headroom that many modern flight sims benefit from. In Microsoft Flight Simulator, which is known for being CPU-intensive at lower resolutions, the 2600's single-core performance is likely the reason why the 1080p Low result of 106.2 FPS is not higher, as newer CPUs with higher IPC would push that number further.
