Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title, and the combination of the Intel Core Ultra 5 225 and AMD Radeon RX 6650 XT produces a set of results that clearly delineate the boundaries of both components. The measured data shows a system that is capable of smooth, playable frame rates at lower resolutions and settings, but which becomes progressively more constrained as pixel count and graphical fidelity rise. This analysis breaks down the measured FPS across resolutions and settings, contextualizes the combo's overall standing, and examines the specific roles the CPU and GPU play in this simulation.

Resolution Scaling

The FPS data reveals a predictable but steep decline as resolution increases, a pattern that points directly at the GPU as the primary bottleneck at higher settings. At 1080p Low, the system achieves an average of 105 FPS. Moving to 1440p Low drops this to 84 FPS, a 20% reduction. At 4K Low, the average falls to 62 FPS, which is a further 26.2% drop from 1440p. This scaling is consistent with a GPU that is being pushed harder with each additional pixel rendered, but the frame rates remain playable at Low settings even at 4K.

The scaling behavior changes character when the quality preset is increased. At Medium settings, the average FPS goes from 81 at 1080p, to 66 at 1440p, and finally to 48 at 4K. The percentage drop from 1080p to 1440p is 18.5%, and from 1440p to 4K is 27.3%. This pattern suggests that while the GPU is still the limiting factor, the increased graphical load from the Medium preset is compounding the resolution penalty. The trend becomes even more pronounced at High settings, where 1080p yields 61 FPS, 1440p yields 49 FPS (a 19.7% drop), and 4K yields 36 FPS (a 26.5% drop from 1440p).

The most demanding scenario, Ultra settings, shows the system's limits. At 1080p Ultra, the average is 58 FPS. At 1440p Ultra, it drops to 47 FPS (a 19% drop), and at 4K Ultra, it falls to a 35 FPS average. The consistency of the percentage drops across the Medium, High, and Ultra presets—all hovering around 20% for the 1080p-to-1440p step and 26-27% for the 1440p-to-4K step—strongly suggests that the RX 6650 XT is the dominant limiting component at these quality levels. The CPU, with its 10 cores and 10 threads, has enough headroom to feed the GPU at lower resolutions, but as the GPU's workload increases with resolution, it simply runs out of processing power. The data indicates that a user targeting 4K will need to rely on the Low preset to get a playable 62 FPS, while 1440p gaming is viable at Medium or High settings.

How This Combo Ranks

Within the database of tested combinations for Microsoft Flight Simulator, this specific pairing of the Intel Core Ultra 5 225 and AMD Radeon RX 6650 XT holds a rank of 1902 out of 2996 total combos. This places it in the lower-middle tier of all systems tested for this game, which is a reasonable expectation for a mid-range GPU paired with a newer, capable CPU. The rank is a holistic measure that suggests that while this combo can run the game, it will not be delivering top-tier performance or maximum settings at high resolutions.

The CPU itself, however, is a strong performer. Its average benchmark score of 36938 places it in the 85th percentile of all CPUs, and its nearest rivals include the AMD Ryzen 5 5600F (with a deltaPct of 0), the AMD Ryzen 5 5500X3D (deltaPct -0.2), and the AMD Ryzen AI 7 PRO 450 (deltaPct -0.4). This indicates that the Core Ultra 5 225 is essentially performance-equivalent to these chips, with differences of less than 1% in aggregate benchmark scores. This is a positive sign for the CPU's ability to handle game logic and draw calls, but its high standing is not enough to overcome the GPU's limitations in this specific title.

The GPU's relative standing is lower. It sits in the 65th percentile of all GPUs with an average score of 19765. Its nearest rivals, such as the NVIDIA Tesla K40m (deltaPct -0.6) and the AMD FirePro D300 (deltaPct 0.7), are professional or older workstation cards. This comparison highlights that the RX 6650 XT is a solid mainstream gaming card, but it is not a high-end performer. The combo's rank of 1902 out of 2996 is a direct reflection of this GPU-class ceiling. The data suggests that the CPU is not holding the system back to a significant degree; rather, the GPU is the component that dictates the overall experience in Microsoft Flight Simulator.

GPU Role

The AMD Radeon RX 6650 XT is the central component determining frame rates in this configuration, and its specifications align with the observed performance drops. The GPU is built on the RDNA 2.0 architecture with a Navi 23 chip and has 8 GB of GDDR6 memory on a 128-bit bus, providing a memory bandwidth of 280.3 GB/s. This memory configuration is a critical factor for Flight Simulator, which relies heavily on streaming vast amounts of terrain and texture data.

The 8 GB VRAM capacity is likely the reason for the significant performance differences between the Low and High presets at the same resolution. At 4K, the average FPS drops from 62 on Low to 36 on High, a 42% reduction. While some of this is due to increased shader complexity, a large portion is likely due to the GPU exceeding its memory capacity or bandwidth, forcing it to stream data from system memory rather than the dedicated VRAM. The clock speeds are high, with a boost clock of 2635 MHz and a game clock of 2410 MHz, which helps maintain performance when memory is not the bottleneck. The 2048 shading units and 64 ROPs are adequate for 1080p and 1440p rendering, but they are simply overwhelmed by the 4K pixel count at higher settings.

The benchmark data for the GPU supports this analysis. Its Passmark G3D score is 17166, which is a moderate score for a card in this class. In contrast, its DirectX 12 score is notably lower at 62, suggesting that its performance in modern, API-heavy workloads might be less competitive than its raw compute capabilities suggest. The GPU's 65th percentile ranking reinforces the idea that it is a capable mid-range part, but its performance is limited by its 8 GB memory pool and 128-bit bus in a game like Microsoft Flight Simulator that is known for being memory-hungry.

Measured FPS Breakdown

The measured FPS data provides a clear picture of the system's capabilities across all presets and resolutions.

At 1080p, the system is generally playable. The Ultra preset yields an average of 58 FPS, which is just below the 60 FPS target for smooth gameplay. The High preset offers a better experience with an average of 61 FPS. The Medium preset produces an average of 81 FPS, with a minimum of 69 and a maximum of 94, providing a comfortable margin above the 60 FPS threshold. The Low preset delivers the highest performance at an average of 105 FPS, making it ideal for high-refresh-rate monitors or competitive play.

At 1440p, the strain begins to show. The Ultra preset drops to an average of 47 FPS, which is not ideal for a smooth experience. The High preset manages an average of 49 FPS, still below the 60 FPS target. The Medium preset is the sweet spot here, with an average of 66 FPS (minimum 56, maximum 75), offering a playable experience. The Low preset remains very playable at an average of 84 FPS.

At 4K, the system's limitations are pronounced. The Ultra preset yields an average of just 35 FPS, and the High preset is not much better at 36 FPS. The Medium preset, with an average of 48 FPS (minimum 41, maximum 56), is the most demanding preset that can be considered borderline playable. The Low preset is the only one that provides a fully smooth experience, with an average of 62 FPS.

The data indicates a clear performance hierarchy. The CPU and GPU combo is capable of high frame rates at 1080p, but the experience degrades significantly with each step up in resolution, particularly at higher quality presets. The minimum FPS figures for the Medium preset (69 at 1080p, 56 at 1440p, and 41 at 4K) show that even in this moderate setting, there are dips that could cause noticeable stutters, especially at 4K.

FAQ

Q: Can this system run Microsoft Flight Simulator at 4K?

A: Yes, but only at the Low preset, where it achieves an average of 62 FPS. At Medium settings, the average drops to 48 FPS, which may be acceptable for some, but High and Ultra settings produce averages of 36 and 35 FPS respectively, which are not recommended for a smooth experience.

Q: What is the best resolution and settings combo for a 60 FPS target?

A: At 1080p, the High preset achieves 61 FPS. At 1440p, the Medium preset achieves an average of 66 FPS with a minimum of 56, making it the highest quality setting that maintains a near-60 FPS floor. 4K gaming is only viable on Low settings, which hits an average of 62 FPS.

Q: Is the Intel Core Ultra 5 225 a bottleneck for the RX 6650 XT in this game?

A: The data suggests the CPU is not the primary bottleneck. The Core Ultra 5 225 ranks in the 85th percentile of all CPUs and is nearly equivalent to rivals like the AMD Ryzen 5 5600F. The significant performance drops with resolution increases point to the GPU as the limiting factor.

Q: How does the combo rank compared to other tested systems?

A: This specific combination ranks 1902nd out of 2996 tested combos for Microsoft Flight Simulator. This places it in the lower-middle tier of all systems, primarily due to the GPU's performance class.

Q: Is the 8 GB of VRAM on the RX 6650 XT sufficient for this game?

A: The 8 GB of VRAM is a likely cause of the steep performance drop when moving from Low to High settings at 4K (62 FPS to 36 FPS). The game's need to stream large textures appears to exceed the memory capacity or bandwidth at higher settings, causing a significant performance penalty.

Settings Recommendations

Based purely on the measured FPS data, the optimal settings depend heavily on the user's target resolution and performance preference. The data shows that the most balanced experience for a standard 60 FPS target at 1080p is the High preset, which delivers an average of 61 FPS. This provides a solid balance between visual fidelity and smoothness. For players who prefer maximum visual quality and can tolerate lower frame rates, the Ultra preset at 1080p yields 58 FPS, which is still within a playable range. The Medium preset at 81 FPS is the best choice for those seeking a high frame rate buffer, as it provides a significant cushion above 60 FPS.

At 1440p, the recommendation shifts to the Medium preset. It is the only preset that maintains an average above 60 FPS, with a measured 66 FPS, and its minimum of 56 FPS is just below the target but generally acceptable. The High preset's average of 49 FPS is too low for a consistently smooth experience, and the Ultra preset at 47 FPS is not recommended. For 4K gaming, the Low preset is the only viable option for a smooth experience, averaging 62 FPS. While the Medium preset at 48 FPS is technically playable, it will be subject to noticeable frame dips and stutter, as indicated by its 41 FPS minimum.

In summary, the data recommends a quality-over-resolution approach for this combo. A user should prioritize 1080p High or 1440p Medium over 4K High to achieve a playable frame rate. Pushing to 4K requires significant compromises in visual settings, and the experience will be inferior to a lower-resolution, higher-fidelity setup.

CPU Role

The Intel Core Ultra 5 225 plays a supporting role in this configuration, providing ample processing power that is not fully utilized by the GPU in most scenarios. The CPU features 10 cores and 10 threads, a base clock of 3.30 GHz, and a boost clock of 4.90 GHz, built on the Arrow Lake architecture. Its benchmark scores are strong, with a Cinebench R23 multi-core score of 25891 and a single-core score of 3655, placing it in the 85th percentile of all CPUs. This high level of performance ensures that the CPU is not a bottleneck for game logic, physics, and draw calls, which are often the primary CPU tasks in simulation games.

However, the measured FPS data shows that the CPU's potential is not the limiting factor. If the CPU were the bottleneck, we would expect to see similar frame rates across different resolutions, as the CPU's workload would be constant. Instead, the data shows a clear decline in FPS as resolution increases at all settings. For instance, at High settings, the FPS drops from 61 at 1080p to 36 at 4K. This is a clear sign that the GPU is the component being saturated, not the CPU.

The CPU's performance is comparable to its nearest rivals, including the AMD Ryzen 5 5600F (0% delta) and the AMD Ryzen 5 5500X3D (-0.2% delta). This means that swapping the Core Ultra 5 225 for one of these CPUs would likely yield very similar results in this game, as the frame rates would still be dictated by the RX 6650 XT. The CPU's high single-thread performance is beneficial for Flight Simulator, which is known to be sensitive to single-core performance, but it is not enough to compensate for the GPU's lack of raw compute power at higher resolutions. Ultimately, the Core Ultra 5 225 is a capable and non-limiting partner for the RX 6650 XT, but the overall performance ceiling of this combo is defined by the GPU.
