Microsoft Flight Simulator

Microsoft Flight Simulator pairs the AMD Ryzen 5 5500X3D with the AMD Radeon RX 6800 XT to deliver a combination that ranks in the 70th percentile of all tested system pairings for this title. The benchmark data shows a setup that is consistently capable of high frame rates at mainstream resolutions, with performance scaling that clearly identifies the RX 6800 XT as the primary performance limiter as resolution increases. This analysis breaks down the measured results, contextualizes the ranking, and provides actionable settings guidance based strictly on the recorded data.

Resolution Scaling

The measured frame rates reveal a classic GPU-bound scaling pattern across the three tested resolutions. At 1080p with Low settings, the combo produces 153 FPS, but this drops to 123 FPS at 1440p and further to 91 FPS at 4K. This represents a 20% performance hit from 1080p to 1440p, and a further 26% drop from 1440p to 4K. The total reduction from 1080p Low to 4K Low is approximately 41%, which is a substantial loss that points directly to the graphics card struggling to fill the increasing pixel count.

The scaling behavior becomes more pronounced at higher quality presets, which indicates that the GPU is the limiting component. At High settings, the combo delivers 90 FPS at 1080p, 72 FPS at 1440p, and 53 FPS at 4K. The percentage drops are consistent: 20% from 1080p to 1440p and 26% from 1440p to 4K, mirroring the Low preset pattern almost exactly. This uniformity across settings is a hallmark of a GPU-bound scenario, where the CPU has sufficient headroom to feed the graphics card at all tested configurations.

At the Ultra preset, the pattern holds with 85 FPS at 1080p, 69 FPS at 1440p, and 51 FPS at 4K. The drop from 1080p to 1440p is 19%, and from 1440p to 4K is 26%. The consistency of these percentage drops across all four settings presets strongly suggests that the Ryzen 5 5500X3D is not the bottleneck in any of these scenarios. If the CPU were limiting performance, we would expect to see frame rates plateau at lower resolutions, particularly at 1080p, where the GPU has less work to do per frame.

The data shows that the RX 6800 XT's performance envelope is stretched thin at 4K, with average frame rates dipping to 51 FPS at Ultra and only reaching 53 FPS at High. The 91 FPS result at 4K Low is the only 4K configuration that approaches high-refresh-rate territory, but it requires sacrificing most visual fidelity. At 1440p, the situation is much healthier: the combo maintains 69 FPS at Ultra and 72 FPS at High, which are playable for a flight simulator that prioritizes smooth camera panning over twitch reactions. The 1080p results are uniformly strong, with even the Ultra preset hitting 85 FPS, indicating that this resolution is where the combo fully flexes its capabilities.

How This Combo Ranks

The combo's rank in Microsoft Flight Simulator is 882 out of 2996 tested combinations, placing it in the top 29% of all system pairings. This is a strong showing for a mid-range CPU paired with a high-end GPU from the previous generation. The percentile placement suggests that this combination outperforms the majority of systems tested in this game, though it does not crack the top tier reserved for the most extreme hardware configurations.

Contextualizing this rank against the component-level benchmarks provides insight into why this combo performs as it does. The Ryzen 5 5500X3D has an average benchmark score of 37018, which places it at the 85th percentile of all CPUs. Its nearest rivals include the AMD Ryzen 5 5600F with a score of 36945 (0.2% higher), the AMD Ryzen AI 7 PRO 450 with a score of 37093 (0.2% higher), and the Intel Core Ultra 5 225 with a score of 36938 (0.2% higher). The CPU is essentially tied with these competitors, all within a 0.3% margin of each other, which means the CPU is not a differentiator in this system.

The RX 6800 XT, meanwhile, has an average benchmark score of 48477, also at the 85th percentile of all GPUs. Its nearest rivals include the NVIDIA RTX A1000 Mobile with a score of 47743 (1.5% lower), the Intel Arc A550M with a score of 49737 (2.5% higher), and the NVIDIA GeForce RTX 5070 Ti with a score of 49957 (3% higher). The GPU sits in a competitive mid-to-high tier, and its performance in this game aligns with its overall benchmark standing.

The combo rank of 882 out of 2996 indicates that the pairing of these two components is well-balanced for this particular title. The CPU's strong single-threaded performance, evidenced by its PassMark single-thread score of 2941, likely helps maintain stable frame pacing in a game that is known for heavy simulation logic. The GPU's 16 GB of VRAM and high memory bandwidth of 512.0 GB/s ensure that texture streaming and high-resolution assets are handled without stutter. The data shows that this combo is not a top-tier performer, but it consistently lands in the upper third of all tested systems, which is a respectable result for hardware that is not the latest generation.

GPU Role

The AMD Radeon RX 6800 XT is the dominant component in this system, and its specifications directly explain the measured frame rates. The GPU features 16 GB of GDDR6 memory on a 256-bit bus, providing a memory bandwidth of 512.0 GB/s. This is a substantial amount of VRAM for a flight simulator, which is notorious for loading large textures and detailed scenery. The 16 GB capacity ensures that the game's high-resolution textures do not exceed available memory, preventing the frame rate dips that occur when the GPU is forced to swap data to system memory.

Clock speeds are also a factor in the performance profile. The GPU has a base clock of 1825 MHz, a game clock of 2015 MHz, and a boost clock of 2250 MHz. The boost clock is particularly relevant for the 4K results, as the GPU can dynamically raise its clock speed when thermal and power headrooms allow. The measured frame rates at 4K, ranging from 51 FPS at Ultra to 91 FPS at Low, suggest that the GPU is hitting its boost limits but still cannot maintain high frame rates at the most demanding resolution. The 20.74 TFLOPS of FP32 compute power is substantial, but Microsoft Flight Simulator's complex rendering pipeline, which includes volumetric clouds and detailed terrain, requires more than raw compute to excel at 4K.

The GPU's 4608 shading units and 288 texture mapping units work in tandem to process the highly detailed environments. The 128 ROPs are responsible for final pixel output, and at 4K resolution, the pixel rate of 288.0 GPixel/s becomes a potential bottleneck. This explains why the frame rates at 4K cluster tightly between 51 and 53 FPS for High and Ultra settings, as the ROP throughput limits the final output regardless of the compute load. The GPU's 72 ray tracing cores are present, but the benchmark data does not indicate that ray tracing is enabled in these tests, so their contribution to the measured results is minimal.

The VRAM configuration is particularly advantageous for this game. With 16 GB available, the GPU can hold large portions of the flight world in memory, reducing the need for constant streaming from the system's DDR4 memory. The memory clock runs at 2000 MHz, which translates to 16 Gbps effective, and the 512.0 GB/s bandwidth is sufficient to feed the GPU's compute units without starving them. In comparison to the CPU's 51.2 GB/s memory bandwidth, the GPU has ten times the bandwidth available, which is a clear indicator that the GPU is designed to handle large data transfers that the CPU cannot.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings presets. At 1920x1080, the combo delivers its best results across the board. The Low preset achieves an average of 153 FPS, which is exceptionally high for a flight simulator and indicates that the CPU and GPU are both operating well within their limits. The Medium preset drops to 119 FPS, with a minimum of 101 FPS and a maximum of 137 FPS, showing a stable frame rate range. The High preset yields 90 FPS, and the Ultra preset produces 85 FPS. The gap between High and Ultra is only 5 FPS, suggesting that the Ultra preset's additional visual effects are not particularly demanding at this resolution.

Moving to 2560x1440, the frame rates remain strong but show the expected decline. The Low preset delivers 123 FPS, which is 30 FPS lower than at 1080p. The Medium preset averages 96 FPS, with a minimum of 82 FPS and a maximum of 110 FPS. The High preset drops to 72 FPS, and the Ultra preset lands at 69 FPS. The spread between Low and Ultra at 1440p is 54 FPS, which is a wider gap than at 1080p, indicating that the GPU is becoming more sensitive to settings changes as resolution increases. The Medium preset's minimum of 82 FPS suggests that even in demanding scenes, the combo can maintain a playable frame rate.

At 3840x2160, the frame rates take a significant hit. The Low preset averages 91 FPS, which is still playable, but the Medium preset drops to 71 FPS with a minimum of 60 FPS. The High preset averages 53 FPS, and the Ultra preset averages 51 FPS. The gap between Medium and High is 18 FPS, which is the largest jump between any two adjacent settings at any resolution. This indicates that the High preset introduces a substantial increase in rendering complexity that the GPU cannot fully absorb at 4K. The Ultra preset's 51 FPS is just above the threshold for playable, but the lack of minimum FPS data for High and Ultra means we cannot confirm how stable these averages are during intense moments like flying over dense cityscapes.

Settings Recommendations

Based on the measured data, the optimal settings depend heavily on the target resolution. At 1080p, the Ultra preset is the clear recommendation. The 85 FPS average is more than sufficient for smooth gameplay, and the 5 FPS difference from High is a small price to pay for the visual improvements that Ultra typically provides. The Medium preset at 119 FPS is also viable for users who prioritize frame rate over visuals, but the Ultra preset's 85 FPS is already well above the 60 FPS threshold that most players consider acceptable.

At 1440p, the High preset offers the best balance. The 72 FPS average is smooth, and the step down to Ultra at 69 FPS provides only marginal visual gains for a 3 FPS loss. The Medium preset at 96 FPS is also a strong option, but the jump to High is worth the 24 FPS sacrifice for the improved detail. The Low preset at 123 FPS is overkill for most users and unnecessarily sacrifices visual quality. For users with high-refresh-rate monitors, the Medium preset at 96 FPS is the sweet spot, as it stays above 90 FPS while maintaining a reasonable level of detail.

At 4K, the situation is more nuanced. The Low preset at 91 FPS is the only configuration that provides a high frame rate, but it does so by stripping away most of the visual fidelity that makes Microsoft Flight Simulator impressive. The Medium preset at 71 FPS is the best compromise, offering a playable frame rate while retaining a moderate level of detail. The minimum FPS of 60 for Medium suggests that even in worst-case scenes, the frame rate does not drop below the playable threshold. The High and Ultra presets at 53 and 51 FPS, respectively, are marginal and may result in noticeable stuttering during complex scenes, though the data does not include minimum FPS values for these presets. For most users, the Medium preset at 4K is the recommended choice, as it provides the best combination of visual quality and performance. Users who prioritize frame rate above all else should consider the Low preset, but they should be aware that the game's visuals will be significantly reduced.
