Microsoft Flight Simulator

Microsoft Flight Simulator with an AMD Ryzen 9 5950X and NVIDIA GeForce RTX 4080 SUPER demonstrates a system that is heavily GPU-bound at higher resolutions but reveals CPU headroom at 1080p. The measured frames per second (FPS) data shows a clear pattern where the performance cost of resolution scaling is substantial, yet the system maintains playability across all tested configurations. This combination ranks in the 93rd percentile of CPUs and 88th percentile of GPUs, placing it as a top-tier pairing for this flight simulator.

Resolution Scaling

The FPS drop from 1080p to 4K is significant and indicates the RTX 4080 SUPER is the primary limiting factor at higher resolutions. Moving from 1920x1080 to 3840x2160 at Ultra settings, the average FPS falls from 118.9 to 70.4, a reduction of 48.5 FPS. This 40.8% performance decrease at the same quality preset underscores that the GPU's rendering workload scales dramatically with pixel count. At High settings, the same resolution jump sees FPS drop from 120.1 to 72.6, reinforcing that the graphics card's compute and memory bandwidth are the bottlenecks when pushing 4K.

The scaling pattern shifts when examining lower settings. At Low settings, the transition from 1080p to 4K yields a drop from 184.8 FPS to 119.9 FPS, which is a smaller absolute loss of 64.9 FPS but still a 35.1% reduction. This suggests that even with minimal graphical demands, the GPU's fill rate and memory subsystem are taxed enough at 4K to prevent the CPU from becoming the sole constraint. The 1440p results sit predictably between the two extremes, with High settings producing 96.4 FPS and Low settings reaching 168.2 FPS.

The data indicates that this combo is best suited for 1440p gaming, where the balance between CPU and GPU load allows for high frame rates without the severe penalties seen at 4K. At 1080p, the system appears CPU-limited in certain scenarios, as evidenced by the smaller FPS gains when lowering settings from High to Low (120.1 to 184.8) compared to the gains seen at 1440p (96.4 to 168.2). The 4K results, while playable, show that the RTX 4080 SUPER's 16 GB of VRAM and 256-bit memory bus are adequate but not overkill for this simulation's highest demands.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is the dominant component in this pairing, with its 16 GB of GDDR6X memory and 736.3 GB/s bandwidth proving sufficient for the game's texture-heavy environments. The GPU's boost clock of 2550 MHz and 52.22 TFLOPS of FP32 compute power drive the high frame rates observed at 1440p and 1080p. Benchmark results show the GPU scores 34245 in Passmark G3D, placing it in the 88th percentile of all GPUs, with nearest rivals including the AMD Radeon RX 6900 XT (0.2% faster) and AMD Radeon Pro W6600M (0.4% faster).

The VRAM capacity is critical for Microsoft Flight Simulator, which loads vast terrain and aircraft detail. At 4K Ultra, the 70.4 FPS average suggests the GPU is working near its limits, but the 16 GB frame buffer prevents any memory-related stuttering that could occur with smaller capacities. The memory clock of 1438 MHz (23 Gbps effective) contributes to the 736.3 GB/s bandwidth, which is essential for streaming high-resolution textures without causing CPU stalls.

Compared to its nearest rivals, the RTX 4080 SUPER's performance is tightly clustered. It sits only 0.2% behind the RX 6900 XT and 2.1% ahead of the RX 7700S, indicating that within this performance tier, architectural differences yield minimal FPS variances in this game. The GPU's Ada Lovelace architecture, built on a 5 nm process, provides efficient power delivery (320 W TDP) that allows sustained boost clocks during long flight sessions, which is a qualitative advantage not fully captured by average FPS numbers.

CPU Role

The AMD Ryzen 9 5950X provides substantial processing headroom, with 16 cores and 32 threads running at a base clock of 3.40 GHz and boost up to 4.90 GHz. This Zen 3 architecture CPU, built on a 7 nm process, scores 38607 in Cinebench R23 multicore and 5450 in single-core, placing it in the 93rd percentile of all CPUs. Its nearest rival, the Intel Core i5-14600K, is only 0.2% faster, while the AMD EPYC 4345P trails by 1.1%.

In this game, the CPU's role becomes more apparent at 1080p where the GPU has less work to do. The FPS difference between 1080p Low (184.8 FPS) and 1440p Low (168.2 FPS) is only 16.6 FPS, suggesting that the CPU is still supplying enough draw calls and physics calculations to keep the GPU fed even as resolution increases. However, at 4K Low (119.9 FPS), the GPU becomes the clear bottleneck, as the same CPU can only push 119.9 FPS compared to the 184.8 FPS at 1080p.

The 64 MB L3 cache is particularly beneficial for this simulation, which involves complex flight models and dynamic weather systems that require rapid access to frequently used data. The CPU's 51.2 GB/s memory bandwidth, while modest compared to the GPU's, is adequate for feeding the 16 cores without creating a data pipeline bottleneck. The single-thread performance, as measured by Cinebench R23 at 5450, ensures that the game's primary simulation thread runs efficiently, which is critical for maintaining consistent frame times during complex maneuvers.

How This Combo Ranks

This combination of AMD Ryzen 9 5950X and NVIDIA GeForce RTX 4080 SUPER ranks 125th out of 1795 tested combos in Microsoft Flight Simulator, placing it in the top 7% of all configurations. This high ranking reflects the synergy between a top-tier CPU and a high-end GPU, though it is not the absolute best due to the availability of newer components. The CPU's 93rd percentile ranking is slightly below the GPU's 88th percentile, indicating that the processor has more headroom relative to its peers than the graphics card.

The rank suggests that while this combo delivers excellent performance, there are 124 other combinations that achieve higher FPS in this game. These likely include newer CPUs with higher single-thread performance or GPUs with more VRAM, but the measured data shows that this pairing still provides a smooth experience at all tested settings. The deltaPct values for the CPU's nearest rivals show that the 5950X is essentially tied with the Intel Core i5-14600K (-0.2%) and i5-14600KF (-0.6%), meaning that CPU choice in this tier has minimal impact on overall ranking.

For the GPU, the nearest rival deltas (0.2% to 2.9%) are similarly small, suggesting that the overall combo rank is more sensitive to the specific game's optimization than to minor hardware differences. The 125th rank out of 1795 combos is a strong result, indicating that users can expect consistent high-frame-rate performance without needing to resort to the most extreme hardware available.

Measured FPS Breakdown

At 1920x1080, the system delivers excellent performance across all settings. Low settings produce 184.8 FPS, Medium reaches 160.8 FPS, High maintains 120.1 FPS, and Ultra drops slightly to 118.9 FPS. The minimal difference between High and Ultra (1.2 FPS) suggests that Ultra settings are highly viable at 1080p without significant performance penalties.

Moving to 2560x1440, the FPS numbers remain strong. Low settings hit 168.2 FPS, Medium achieves 129.4 FPS, High produces 96.4 FPS, and Ultra settles at 94 FPS. The gap between High and Ultra widens to 2.4 FPS, but both are playable for competitive or immersive flight simulation.

At 3840x2160, the performance drops become more pronounced. Low settings yield 119.9 FPS, Medium reaches 96.2 FPS, High maintains 72.6 FPS, and Ultra drops to 70.4 FPS. The difference between High and Ultra shrinks to 2.2 FPS, indicating that 4K Ultra is achievable but with a noticeable FPS cost compared to lower resolutions. The 4K Low result of 119.9 FPS closely matches the 1080p High result of 120.1 FPS, showing that resolution scaling at low settings has a similar performance impact as a two-tier settings increase at 1080p.

Settings Recommendations

For the best balance of visual fidelity and frame rate, the Medium preset at 2560x1440 offers the most compelling experience. The 129.4 FPS average is well above the 60 FPS threshold for smooth simulation, and the visual improvement over Low settings is substantial. At 1080p, High settings (120.1 FPS) are recommended over Ultra (118.9 FPS) since the 1.2 FPS difference is negligible, and High likely reduces some unnecessary graphical effects that do not enhance the core flight experience.

At 4K, the data shows that High settings (72.6 FPS) provide a better experience than Ultra (70.4 FPS) due to the marginal FPS gain, but users with high-refresh-rate 4K displays should consider Medium (96.2 FPS) to ensure smoother motion. The Low preset at 4K (119.9 FPS) is only recommended for users prioritizing maximum frame rates over visual quality, as the simulation's scenic detail is a key part of the experience. For most users, 1440p Medium or High offers the ideal compromise, as the system is not GPU-bound at these settings and can maintain high frame rates without compromising the intricate world rendering.
