Microsoft Flight Simulator

The AMD Ryzen 5 3600 and AMD Radeon RX 6600 XT combination delivers a playable but demanding experience in Microsoft Flight Simulator, with performance scaling tightly bound to both resolution and the preset menu. The measured frames per second reveal a system that can handle the simulation’s heaviest visual loads only at lower resolutions, while higher settings at 4K push the combo to the edge of playability.

Resolution Scaling

The data shows a steep and consistent performance penalty as resolution climbs, a pattern that points directly at the GPU as the primary bottleneck at higher pixel counts. At 1080p with Low settings, the combo produces an average of 102.4 FPS, which is a strong result for a flight sim. Moving to 1440p at the same Low preset drops the average to 82.9 FPS, a 19% reduction. The jump to 2160p Low further reduces the average to 57.5 FPS, which is another 31% loss from the 1440p figure. This scaling is not linear, and the increasingly large drops at 4K indicate that the Radeon RX 6600 XT’s 8 GB frame buffer and 256.0 GB/s memory bandwidth are being saturated by the higher pixel throughput.

The pattern becomes more pronounced when the preset is raised to High. At 1080p High, the average is 57 FPS. At 1440p High, that falls to 45.7 FPS, a 20% drop. At 4K High, the average plummets to 31.5 FPS, a 45% reduction from the 1080p figure. This confirms that the GPU is the limiting component at higher resolutions. The CPU’s role is more evident at 1080p, where the gap between Low and Ultra presets is smaller than at 4K, suggesting that the Ryzen 5 3600’s six cores and twelve threads are keeping up with the simulation’s draw calls at lower pixel counts.

The Ultra preset shows the most severe scaling. From 1080p Ultra at 58.7 FPS, the combo drops to 44.4 FPS at 1440p Ultra, and then to 33.3 FPS at 4K Ultra. The delta between 1080p and 4K Ultra is 43%, which is nearly identical to the loss seen on the High preset. This consistency suggests that the game’s Ultra settings impose a fixed rendering cost that scales directly with resolution, and the GPU’s compute resources are the deciding factor. At 4K, no preset achieves a 60 FPS average, and the highest recorded frame rate at that resolution is 57.5 FPS on Low, which is still below the ideal smoothness threshold for many users.

GPU Role

The Radeon RX 6600 XT is built on the RDNA 2.0 architecture with 2048 shading units, 128 texture mapping units, and 64 render output units. Its boost clock is rated at 2589 MHz, with a game clock of 2359 MHz. The 8 GB of GDDR6 memory on a 128-bit bus delivers 256.0 GB/s of bandwidth. These specifications place the card in the 71st percentile of all GPUs, with an average benchmark score of 27985. Its nearest rival in aggregate benchmarks is the NVIDIA GeForce GTX 980 Ti, which scores 27956, a delta of 0.1%. This means the RX 6600 XT is essentially tied with that older flagship in synthetic tests, but the data from Microsoft Flight Simulator shows how real-world workloads differ.

The game’s measured results at 4K are revealing. At 4K Low, the GPU produces 57.5 FPS, which is respectable, but at 4K Medium it drops to 47.3 FPS, and at 4K High it falls to 31.5 FPS. The VRAM capacity appears sufficient for this game at these settings, as there is no sudden collapse in performance that would indicate memory swapping. Instead, the limiting factor is the raw fill rate and shading throughput. The pixel rate is 165.7 GPixel/s and the texture rate is 331.4 GTexel/s, but those figures are not enough to maintain high frame rates at 4K with the game’s complex scenery and lighting. The card’s FP32 throughput of 10.60 TFLOPS is adequate for 1080p and 1440p, but the 4K results show a clear ceiling.

The GPU’s nearest rivals in the benchmark database include the NVIDIA GeForce RTX 3070, which scores 28238, a delta of -0.9% relative to the RX 6600 XT. That comparison is misleading for this game, as the RTX 3070 typically has a larger memory bus and more bandwidth, but the data here only covers average scores, not specific game performance. The RX 6600 XT’s 128-bit bus is a known constraint, and the measured FPS at 4K High and Ultra, hovering around 31-33 FPS, aligns with that hardware limitation. The 16 Gbps effective memory speed helps, but it cannot compensate for the narrow interface when pixel counts rise.

Settings Recommendations

The measured rows indicate that the best balance of visual fidelity and frame rate for this combo is found at 1440p with the High preset. At that resolution and setting, the average is 45.7 FPS, which is playable but not smooth. Dropping to Medium at 1440p yields 62.8 FPS, a substantial improvement of 37% over High, with a modest reduction in visual quality. For users prioritizing a consistent frame rate, 1440p Medium is the sweet spot. At 1080p, the High preset delivers 57 FPS, which is close to the 60 FPS target, and Ultra pushes that to 58.7 FPS, suggesting that the CPU is not a limiting factor at this resolution.

At 4K, the data shows that only the Low preset, at 57.5 FPS, approaches a playable level. The Medium preset at 4K drops to 47.3 FPS, and High falls to 31.5 FPS. The Ultra preset at 4K is the worst performer, with an average of 33.3 FPS. This means that for 4K displays, users must accept significant compromises. The Low preset is the only viable option for a semi-fluid experience, but it sacrifices most of the game’s visual detail. The recommended path is to avoid 4K entirely with this GPU and instead target 1440p, where Medium or High presets offer a reasonable trade-off. The data does not support using Ultra at any resolution above 1080p, as the frame rate drops below 45 FPS at 1440p and below 34 FPS at 4K.

How This Combo Ranks

The combination of the Ryzen 5 3600 and the RX 6600 XT ranks 1275 out of 1795 tested combos in Microsoft Flight Simulator. This places it in the lower third of all configurations, which is a strong signal that this pairing is not optimized for this particular game. The rank is a composite measure that likely accounts for both CPU and GPU performance across various settings and resolutions. Given that the CPU sits in the 76th percentile of all processors and the GPU sits in the 71st percentile, the low combo rank suggests that the game is particularly demanding on the GPU’s memory subsystem and the CPU’s single-thread performance.

The CPU’s nearest rivals in aggregate benchmarks include the Intel Core i5-11400, which scores 18150, a delta of -0.1%, and the AMD Ryzen 5 7535HS, which scores 18101, a delta of 0.2%. This means the Ryzen 5 3600 is effectively performance-equivalent to those chips in general workloads. However, in Microsoft Flight Simulator, the combo rank of 1275 indicates that the game does not scale well with the six-core, twelve-thread configuration. The game’s flight simulation engine tends to favor fewer, faster cores, and the Ryzen 5 3600’s boost clock of 4.20 GHz is adequate but not exceptional. The 32 MB of shared L3 cache helps with the game’s asset streaming, but it does not overcome the GPU’s limitations at higher resolutions.

The GPU’s rank relative to its own rivals is more telling. The RX 6600 XT is only 0.1% ahead of the NVIDIA GeForce GTX 980 Ti in aggregate scores, but in this game, the newer architecture does not translate to a proportional advantage. The RTX 3070, which scores 28238, is 0.9% higher in aggregate, but the RX 6600 XT’s 8 GB memory size and 128-bit bus are likely the reasons the combo ranks so low. The data suggests that other combos with similar CPU scores but more capable GPUs would rank significantly higher, as the game’s performance ceiling is clearly set by the graphics card at 1440p and above.

CPU Role

The AMD Ryzen 5 3600 is a six-core, twelve-thread processor based on the Zen 2 architecture, codenamed Matisse, manufactured on a 7 nm process. Its base clock is 3.60 GHz and its boost clock is 4.20 GHz. The CPU has a 32 MB shared L3 cache, which is beneficial for the game’s continuous loading of terrain and aircraft models. In synthetic benchmarks, the CPU scores 15045 in Cinebench R23 multicore and 2124 in single-core, placing it in the 76th percentile of all CPUs. Its average benchmark score is 18129, with a passmark single-thread score of 2562.

In Microsoft Flight Simulator, the CPU’s role is most evident at 1080p, where the GPU is less stressed. The data shows that at 1080p, the average FPS remains above 57 FPS across all presets, from Low at 102.4 FPS to Ultra at 58.7 FPS. This narrow range suggests that the CPU is able to feed the GPU adequately at this resolution. However, the CPU’s single-thread performance, which is critical for the game’s main simulation loop, appears to cap the maximum frame rate. The 1080p Low result of 102.4 FPS is the highest recorded, and it is likely limited by the CPU’s boost clock and IPC, rather than the GPU, which could push higher frames at that low preset.

The CPU’s nearest rivals in aggregate scores include the AMD Ryzen 5 1600, which scores 18158, a delta of -0.2%, and the AMD EPYC 9274F, which scores 18189, a delta of -0.3%. The Ryzen 5 3600 is slightly slower than the Ryzen 5 1600 in aggregate, which is surprising given the generational leap, but it highlights that the game does not heavily utilize the additional threads. The CPU’s 12 threads are underutilized in this flight sim, as the game’s engine is not highly parallel for the main rendering thread. The data suggests that a CPU with higher single-core performance, even with fewer cores, would yield better results at 1080p. At higher resolutions, the CPU’s influence diminishes, as the GPU becomes the bottleneck, but the combo rank of 1275 indicates that the overall pairing does not excel in either CPU-bound or GPU-bound scenarios.
