Microsoft Flight Simulator

The AMD Ryzen 5 9600X paired with the NVIDIA GeForce RTX 4080 delivers a strong showing in Microsoft Flight Simulator, a title known for its punishing demands on both the CPU and GPU. The measured data reveals a system that is clearly GPU-bound at higher resolutions but retains enough headroom to push very high frame rates at 1080p. This combination ranks in the top tier of tested configurations, placing 215th out of 3714 combos, putting it in the 94th percentile of all pairings tested. The results reflect a hardware pairing that can handle the simulator’s complex scenery rendering without significant bottlenecks, though the balance between the 6-core processor and the high-end graphics card shifts noticeably depending on the resolution you choose.

Resolution Scaling

The frame rate scaling from 1080p to 4K is informative about where the performance bottleneck lies. At 1080p with Low settings, the combo produces 211 FPS. Moving to 1440p Low drops that to 170 FPS, a decrease of 41 frames, and then to 4K Low, it falls to 125 FPS, a further drop of 45 frames. This pattern shows that even at the lowest settings, the load on the GPU is increasing steeply with resolution. The transition from 1080p High (123 FPS) to 1440p High (99 FPS) is a 24 FPS loss, and then to 4K High (73 FPS) is another 26 FPS loss. The scaling is relatively consistent, indicating a GPU-bound scenario at these settings.

However, the most telling data point is the Ultra setting. At 1080p Ultra, the system produces 117 FPS. At 1440p Ultra, it drops to 95 FPS, and at 4K Ultra, it hits 70 FPS. The 1080p to 1440p drop is 22 FPS, while the 1440p to 4K drop is 25 FPS. These numbers point to a system where the CPU is still doing heavy lifting at 1080p, but the GPU becomes the primary limit as resolution climbs. The fact that the 1080p Ultra (117 FPS) is not significantly higher than 1440p Ultra (95 FPS) indicates that the CPU is holding back the frame rate at the lower resolution, preventing the GPU from fully stretching its legs. By 4K, the GPU is clearly the limiting component, and the frame rates align more predictably with the GPU’s rendering capacity.

The data shows that the RTX 4080 is powerful enough to keep frame rates above 70 FPS even at 4K, but the CPU’s single-thread performance is a limiting factor at lower resolutions. In Microsoft Flight Simulator, the simulation and scenery processing tasks are heavily single-threaded, and the Ryzen 5 9600X’s strong single-core score of 1253 in 3DMark single-thread helps, but it still leaves some performance on the table. The scaling pattern is typical of a system where the GPU is not fully saturated until you reach 4K, meaning that users with high refresh rate 1080p or 1440p monitors will not see the frame rates they might expect from the GPU alone. The data suggests that while the combo is highly capable, it is optimized for 4K gaming, where the GPU is fully engaged.

Settings Recommendations

For the optimal balance of visual quality and frame rate, the High preset is the clear winner. At 4K High, the system delivers 73 FPS, which is comfortably above the 60 FPS threshold and provides a smooth experience for a flight simulator. The jump from High to Ultra at 4K is only a 3 FPS loss (73 to 70 FPS), which is a negligible difference, so Ultra is also a strong choice if you want the best visual fidelity without a significant performance penalty. However, the Medium preset at 4K offers 97 FPS, which is a substantial 24 FPS improvement over High, and this comes with the only recorded min FPS data: 83 FPS at 4K Medium. This suggests that Medium provides a more stable frame time experience, as the minimum frame rate is still high, which is critical for a smooth flight experience over dense scenery.

At 1440p, the High preset gives 99 FPS, which is excellent for a high refresh rate monitor, and Ultra at 95 FPS is also very playable. The Medium preset at 1440p yields 132 FPS, and it also has a min FPS of 112, showing that the variance is low. For 1080p, the High preset at 123 FPS is ideal for high refresh rate displays, but the Medium preset at 164 FPS offers a much higher headroom, with a min of 139 FPS, which is still incredibly smooth. The Ultra preset at 1080p (117 FPS) is close to High (123 FPS), indicating that the CPU is limiting the Ultra setting, so the extra GPU load from Ultra is not being translated into higher frame rates.

The data indicates that the Medium preset offers the best trade-off between visual quality and performance across all resolutions. At 4K, it provides a 27 FPS improvement over High, and at 1440p, it gives a 33 FPS improvement. The measured min FPS figures for Medium at each resolution (83 FPS at 4K, 112 FPS at 1440p, 139 FPS at 1080p) are all well above 60 FPS, so there is no risk of stuttering. For a simulator where you are often looking at detailed scenery, the added smoothness of Medium over Low is worth the small visual sacrifice. The Low preset is not recommended, as it does not show any advantage in frame rate at 1080p and 1440p; the CPU becomes the limiting factor, and the visual quality drops significantly for no real gain. The Ultra preset is best reserved for lower resolutions where the GPU is not the bottleneck, but even then, the gains over High are marginal.

GPU Role

The RTX 4080 is a high-end GPU with 16 GB of GDDR6X memory and a 256-bit memory bus, which provides a memory bandwidth of 716.8 GB/s. This is a critical specification for Microsoft Flight Simulator, which streams vast amounts of textures and terrain data. The 16 GB VRAM capacity ensures that the game will not run out of memory even at 4K Ultra settings, and the high bandwidth allows for rapid loading of scenery as you fly. The GPU’s 9728 shading units and 76 RT cores are also well-suited for the game’s use of ray tracing for some visual effects, though none of the measured settings explicitly mention ray tracing.

The clocks for the RTX 4080 are a base of 2205 MHz and a boost of 2505 MHz. The boost clock is essential for handling the sustained load of a flight simulator, where you are constantly rendering new scenery. The data shows that the GPU is the limiting factor at 4K, as the frame rates scale predictably with the resolution. The 4K Ultra score of 70 FPS is a reasonable result for a game this demanding, and the GPU’s capabilities mean that you can expect a consistent 60+ FPS experience at the highest settings. The GPU’s performance is also evident in the passmark G3D score of 34457, which places it in the 86th percentile of all GPUs, and the nearest rival is the RTX 4080 SUPER with a delta of 0.1%, meaning the 4080 is essentially at the same level as its SUPER counterpart.

The GPU’s role in the combo is to provide the raw rendering power, and the data indicates that it is well-matched to the CPU for this title. In the measured results, the GPU is able to scale its performance with the resolution, which is a sign that it is not being held back by the CPU at higher settings. The fact that 4K High (73 FPS) and 4K Ultra (70 FPS) are close suggests the GPU is near its limit, and the 4K Medium (97 FPS) shows that lowering a single setting can unlock a significant performance headroom. The GPU’s memory bandwidth is also relevant when considering the huge asset streaming in the game, and the 716.8 GB/s is sufficient to avoid stuttering. The GPU’s overall score of 54247 in the average benchmark, with a percentile of 86, confirms it is a top-tier part, and the game’s results align with that.

How This Combo Ranks

The combination of the Ryzen 5 9600X and RTX 4080 ranks 215th out of 3714 tested combos, placing it in the top 5.8% of all configurations. This is a strong position, but it is not the absolute top, which suggests that there are combos with more powerful CPUs that can extract more performance from a high-end GPU like the RTX 4080. The rank is a composite of the CPU and GPU scores, and it reflects the balance of the two components. The CPU ranks in the 81st percentile of all CPUs, with an average benchmark score of 29713, and the GPU ranks in the 86th percentile, with an average score of 54247. The combo itself appears to benefit from the GPU’s strong performance, but the CPU’s single-thread capabilities are a limiting factor in a game like Microsoft Flight Simulator.

The nearest CPU rivals to the Ryzen 5 9600X are the AMD Ryzen 7 PRO 5755GE (0.2% faster), the AMD Ryzen 7 7840H (0.5% slower), the AMD Ryzen 7 5800XT (0.6% slower), and the AMD Ryzen 7 8845HS (0.8% slower). These are all within 1% of the 9600X’s performance, which shows that the 9600X is in a competitive mid-range segment. For the GPU, the nearest rival is the RTX 4080 SUPER, which is 0.1% faster, and the AMD Radeon Pro W5700X (1.1% slower), the AMD Radeon RX 6750 GRE 12 GB (2.6% slower), and the AMD Radeon 8060S (2.7% slower). The GPU is essentially on par with the RTX 4080 SUPER, which confirms its performance.

The 215th rank out of 3714 is a solid placement, but it is not a top-tier position because there are many combos with faster CPUs. The data suggests that if you pair the RTX 4080 with a more powerful CPU, you could likely get higher frame rates at 1080p and 1440p, but the GPU would still be the limiting factor at 4K. The rank is a reflection of the overall capability of the system, and for a flight simulator, the 4K performance is the most relevant metric, which the combo handles well. The combo is in the top 6% of all tested, which is a strong recommendation for a high-end gaming PC build.

CPU Role

The AMD Ryzen 5 9600X is a 6-core, 12-thread processor based on the Zen 5 architecture, with a base clock of 3.9 GHz and a boost clock of 5.4 GHz. The high boost clock is crucial for Microsoft Flight Simulator, which is heavily dependent on single-thread performance. The CPU’s single-core score in Cinebench R23 is 2183.5, and in 3DMark it is 1253, both of which are solid figures. The game’s engine is notorious for not scaling well with multiple cores, so the 9600X’s strong single-thread performance is more important than its 6-core count.

The CPU’s performance in this game is evident when you look at the frame rates. At 1080p Low, the system hits 211 FPS, which is a high number, but it is not as high as you might expect from a high-end GPU because the CPU is processing the game’s simulation logic. As you increase the resolution, the GPU takes over, but the CPU still needs to maintain a minimum frame rate. The 1080p Ultra score of 117 FPS is a good example: the GPU is not fully utilized at that resolution, and the CPU is holding back the frame rate. The CPU’s multi-threaded performance is also solid, with a Cinebench R23 multi-core score of 17528.5, but the game does not use all cores effectively.

The CPU’s 32 MB of L3 cache and 1 MB L2 per core are important for the flight simulator, as the game has large assets that need to be accessed frequently. The 9600X’s 65W TDP is low, which is a benefit for system cooling, but the performance is not compromised. The CPU is in the 81st percentile of all CPUs, and the data shows that it is a good match for the RTX 4080. The CPU’s 6 cores and 12 threads are enough for the game, and the high clock speed provides the responsiveness needed for a smooth experience. The CPU and GPU work together well, but the CPU is the one limiting factor at lower resolutions, which is a common trait of this game.

Measured FPS Breakdown

At 1080p with Low settings, the system delivers an average of 211 FPS, which is the highest score in the entire dataset. This is a clear indication that the CPU is the limiting factor at this low resolution, as the GPU is not fully stressed. The Medium settings at 1080p produce an average of 164 FPS, with a minimum of 139 FPS and a maximum of 188 FPS, showing a good frame time consistency. The High preset drops to 123 FPS, and the Ultra preset is at 117 FPS. The difference between High and Ultra is only 6 FPS, which is a minor gain for the visual quality increase. The 1080p data shows that the CPU is the main determinant of the frame rate, as the GPU is waiting for the CPU to finish its calculations.

At 1440p, the scores are more balanced. The Low preset gives 170 FPS, which is 41 FPS lower than 1080p Low, showing the GPU is starting to be a factor. The Medium preset at 1440p is 132 FPS, with a min of 112 FPS and a max of 152 FPS. The High preset is 99 FPS, and the Ultra preset is 95 FPS. The difference between High and Ultra is 4 FPS here, which is even smaller than the 1080p difference, indicating that the GPU is becoming the bottleneck. The 1440p data shows a clear progression where the GPU is more engaged, but the CPU still plays a significant role.

At 4K, the GPU is the primary limit. The Low preset is 125 FPS, the Medium preset is 97 FPS (min 83, max 112), the High preset is 73 FPS, and the Ultra preset is 70 FPS. The jump from Low to Medium is 28 FPS, from Medium to High is 24 FPS, and from High to Ultra is 3 FPS. The High to Ultra is a marginal difference, showing that the GPU is at its limit. The 4K Medium preset is the best balanced, with a 97 FPS average and a min of 83 FPS, which is still a great experience. The 4K data shows that the game is playable even at the highest settings, but the best performance for a smooth experience is at the Medium setting. The data also shows that the minimum FPS for the Medium preset at all resolutions is above 80 FPS, which is a strong indication of the system’s stability.
