Microsoft Flight Simulator

Microsoft Flight Simulator is an exceptionally demanding title, and the measured results for the AMD Ryzen 5 5500X3D paired with the NVIDIA GeForce RTX 3080 reveal a configuration that is highly capable but requires careful settings management to achieve a fluid experience. The data indicates a system that can handle the simulator's complex rendering load, but the margins between playable and taxing settings are tight, especially at higher resolutions. This analysis will break down the measured performance across different presets and resolutions, examining the specific roles of the CPU and GPU in shaping these outcomes.

Settings Recommendations

The measured FPS data for this combination shows a clear hierarchy across the four available presets, with the choice of settings drastically altering the playability of the simulation. For a flight simulator, where smooth camera panning and instrument readability are crucial, maintaining a stable frame rate is paramount. The data suggests that the Medium preset offers the most balanced experience, providing a significant performance uplift over High and Ultra while retaining a level of visual fidelity that is likely sufficient for the core simulation.

At 1920x1080, the Medium preset delivers an average of 123 FPS with a reported minimum of 104 FPS and maximum of 141 FPS. This represents a substantial 31 FPS improvement over the High preset's average of 92 FPS and a massive 35 FPS improvement over the Ultra preset's 88 FPS. The gap between Medium and High is considerable, suggesting that the High preset introduces rendering features that disproportionately tax the system. The minimum FPS of 104 on Medium indicates that even in demanding scenes, the frame rate is unlikely to drop below a very smooth threshold, making it the most reliable preset at this resolution.

Moving to 2560x1440, the Medium preset again emerges as the sweet spot. It averages 99 FPS, with a minimum of 84 FPS and a maximum of 114 FPS. While the average is lower than at 1080p, the minimum of 84 FPS is still comfortably within the range for a smooth experience. The High preset at this resolution drops to 74 FPS, and Ultra falls to 71 FPS. The Medium preset's 25 FPS lead over High at 1440p mirrors the pattern seen at 1080p, reinforcing that the jump from Medium to High is the most costly step in this game's settings hierarchy.

At the demanding 4K resolution (3840x2160), the situation becomes more critical. The Medium preset is the only one that maintains a playable average, at 73 FPS, with a minimum of 62 FPS. This is the only setting at 4K where the average frame rate is comfortably above 60 FPS. The High preset averages 55 FPS, and Ultra drops to 52 FPS, both of which are likely to introduce noticeable stutters and a less fluid experience for a game that thrives on smooth motion. The Low preset at 4K hits 94 FPS, but its visual compromises are likely too severe for a game celebrated for its scenery.

Based on this data, the Medium preset is the recommended starting point for all resolutions. It provides the best compromise between visual quality and performance, ensuring that the frame rate remains high enough to prevent the simulation from feeling sluggish. While the Ultra preset might be tempting for maximum visual fidelity, the performance cost is significant, and the High preset does not offer a meaningful enough improvement over Medium to justify its substantial FPS penalty. For users with high-refresh-rate 1080p displays, the Medium preset will allow the hardware to stretch its legs, while for 4K users, it is arguably the only viable choice for a consistently smooth experience.

CPU Role

The AMD Ryzen 5 5500X3D is a 6-core, 12-thread processor based on the Zen 3 architecture, featuring a base clock of 3.00 GHz and a boost clock of 4.00 GHz. Its most defining feature is the large 96 MB shared L3 cache, which is a significant asset for gaming workloads. In a simulation like Microsoft Flight Simulator, which involves complex world-loading and physics calculations, this large cache can be highly beneficial for reducing latency and improving data throughput. The CPU's benchmark scores, such as a Passmark single-thread score of 2941 and a multithread score of 20363, indicate a solidly performing processor for its class.

The CPU's role in this specific game becomes evident when analyzing the FPS scaling. The data shows that the frame rate is heavily influenced by the resolution and the settings preset, which primarily changes the GPU load. The fact that the FPS drops significantly when moving from Medium to High settings suggests that the GPU is the primary bottleneck in those scenarios. However, the CPU must also keep up with the game's simulation logic. The 6-core/12-thread configuration is likely sufficient to feed the RTX 3080 at most settings, but it may be a limiting factor at lower resolutions and settings where the GPU has spare capacity.

The performance data for the CPU itself shows it sits at the 85th percentile among all CPUs, with an average benchmark score of 37018. Its nearest rivals, such as the AMD Ryzen 5 5600F, have a nearly identical average score, with a delta of just 0.2%. This indicates that the 5500X3D is a very capable processor, but not an outlier in performance. In the context of this game, the CPU's job is to maintain a consistent frame pacing. The fact that the minimum FPS on Medium at 1080p is 104, which is only 19 FPS below the average, suggests that the CPU is managing the game's simulation load effectively without major frame-time spikes. The boost clock of 4.00 GHz, while not the highest, is adequate for the single-threaded tasks that often dominate game logic.

GPU Role

The NVIDIA GeForce RTX 3080 is a high-end graphics card from the Ampere architecture, featuring 10 GB of GDDR6X memory on a 320-bit bus with a bandwidth of 760.3 GB/s. Its core clocks are rated at 1440 MHz base and 1710 MHz boost, and it houses 8704 shading units. This is a powerful GPU, and its 10 GB of VRAM is a key consideration for Flight Simulator, which is known for its high-resolution textures and large draw distances. The GPU's benchmark scores are strong, with a Passmark G3D score of 25086, placing it at the 68th percentile of all GPUs.

The GPU is clearly the dominant factor in this pairing's performance. The FPS scaling across resolutions points directly to the GPU's workload. At 1080p with Low settings, the system achieves 155 FPS, but this drops to 88 FPS at Ultra. This 67 FPS difference is almost entirely due to the increased rendering load on the GPU. The pattern is consistent at all resolutions: as settings are increased, the GPU becomes more saturated, and the frame rate drops. The fact that the FPS does not scale perfectly with resolution suggests that the GPU's memory bandwidth and compute power are being fully utilized at higher settings.

The 10 GB VRAM buffer is a potential point of contention. At 4K with Ultra settings, the system averages 52 FPS, suggesting that the game may be pushing against the VRAM capacity. While the data does not explicitly state VRAM usage, the significant performance drop from Medium to High and Ultra at 4K could be partially attributed to the GPU having to manage a larger amount of texture data. The RTX 3080's 760.3 GB/s of bandwidth is high, but the sheer volume of data required for a flight simulator's terrain and aircraft models at 4K can strain even this resource. The GPU's boost clock of 1710 MHz is a factor in its raw computational throughput, but the game's performance is more likely governed by memory subsystem and shader complexity than raw clock speed alone.

How This Combo Ranks

In the benchmark database, this specific combination of CPU and GPU has a combo rank of 801 out of 2996 tested combinations. This places it in the top 27% of all tested systems, which is a strong showing for a pairing of a mid-range 2025 CPU with a high-end 2020 GPU. The data confirms that this is not a top-tier combination for the absolute highest settings at 4K, but it is a very capable system for high-refresh-rate 1080p and 1440p gaming.

The ranking reflects a system that is balanced but not without compromise. The CPU's performance, while good, is not in the top tier, and it may hold back the GPU in certain CPU-bound scenarios. The GPU, while powerful, is a previous generation model and is outperformed by newer flagships. This combination finds its place as a high-performing mid-range option, capable of delivering excellent frame rates at mainstream resolutions. The fact that it ranks 801st overall suggests that there are many more powerful combinations available, but it also means that this pairing is more than sufficient for a vast majority of users. It is a combination that prioritizes a high level of performance without requiring the absolute top-tier components.

Resolution Scaling

The performance drop from 1080p to 4K is significant and tells a clear story about the limiting component. At the Medium preset, the average FPS goes from 123 at 1080p to 99 at 1440p and finally to 73 at 4K. This is a consistent and expected decline, but the magnitude of the drop is telling. The transition from 1080p to 1440p results in a 24 FPS loss, while the transition from 1440p to 4K results in a 26 FPS loss. This pattern indicates that the GPU is the primary bottleneck, as its workload scales with the number of pixels.

The data reveals a system that is well-balanced at 1440p, where the GPU is still able to maintain a high frame rate. However, at 4K, the GPU's limitations become apparent. The fact that the FPS at 4K on Ultra is just 52 suggests that the GPU is almost fully saturated. The CPU, with its 6 cores and 12 threads, is likely not the limiting factor at 4K because the GPU is so heavily loaded. However, at 1080p with Low settings, where the GPU has less work, the CPU must work harder to maintain the 155 FPS average. The data implies that the CPU can handle this task, as the frame rate remains high, but it is likely approaching its limit.

Measured FPS Breakdown

The complete set of measured FPS data is as follows:

3840x2160 (4K)

• Ultra: Average 52 FPS
• High: Average 55 FPS
• Medium: Average 73 FPS (Min 62, Max 84)
• Low: Average 94 FPS

2560x1440 (1440p)

• Ultra: Average 71 FPS
• High: Average 74 FPS
• Medium: Average 99 FPS (Min 84, Max 114)
• Low: Average 127 FPS

1920x1080 (1080p)

• Ultra: Average 88 FPS
• High: Average 92 FPS
• Medium: Average 123 FPS (Min 104, Max 141)
• Low: Average 155 FPS

This breakdown underscores the non-linear performance scaling. The gap between High and Ultra is consistently small, at just 3 to 4 FPS across all resolutions. This is an interesting finding, suggesting that the Ultra preset adds a rendering feature that has a minimal performance cost relative to High, or that the High preset is already so demanding that the extra step is not as costly. In contrast, the gap between Medium and High is much larger, ranging from 19 FPS at 4K to 31 FPS at 1080p. This indicates that the High preset introduces a major rendering change that significantly increases the GPU load, making Medium the most efficient choice.
