Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding title that scales heavily with both resolution and graphical presets, and the measured data for the Intel Core Ultra 7 155H paired with the NVIDIA GeForce RTX 5050 shows a system that is firmly positioned for 1080p play, with the ability to stretch into 1440p at lower settings. The performance envelope across the three tested resolutions reveals a GPU that is the primary limiting factor, as the frame rate deltas between settings are substantial, while the CPU provides enough headroom to keep the simulation running without becoming a bottleneck at lower resolutions.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and tells a clear story about where the performance ceiling lies. At Low settings, the system delivers 88 FPS at 1920x1080, which drops to 71 FPS at 2560x1440 (a 19% reduction), and further down to 52 FPS at 3840x2160 (a 41% reduction from 1440p). This pattern of diminishing returns as resolution increases is classic GPU-bound behavior; the RTX 5050's 8 GB of GDDR6 memory and 128-bit bus are being saturated by the increasing pixel count, particularly at 4K where the 52 FPS average at Low settings is borderline playable but far from smooth.

At High settings, the scaling is even more pronounced. The system manages 51 FPS at 1080p, but this falls to 41 FPS at 1440p (a 20% drop) and then plummets to 31 FPS at 4K (a 24% drop from 1440p). The 4K High result is the first clear sign of the GPU struggling, as 31 FPS is below the threshold for a comfortable experience in a flight simulator where precise control inputs are required. The Ultra preset tells an even more restrictive story: 49 FPS at 1080p, 39 FPS at 1440p, and just 29 FPS at 4K. The gap between 1440p and 4K at Ultra narrows to only 10 FPS, suggesting that at this preset, the game's visual complexity is overwhelming the GPU's shading units and texture throughput regardless of resolution.

The Medium preset, which is the only one with min and max FPS data recorded, shows a more nuanced picture. At 1080p, the average is 68 FPS with a minimum of 58 FPS and maximum of 78 FPS. At 1440p, the average drops to 55 FPS (a 19% reduction), with a minimum of 47 FPS and maximum of 63 FPS. At 4K, the average falls to 41 FPS (a 25% reduction from 1440p), with a minimum of 35 FPS and maximum of 47 FPS. The consistency of these min/max ranges indicates that the frame pacing remains stable even as the load increases, which is a positive sign for a simulator where stutter can be disorienting.

What the resolution scaling data indicates is that the RTX 5050 is a capable 1080p card for this game, a decent 1440p card at Medium settings, and a 4K card only at Low settings. The 4K Low result of 52 FPS is actually higher than the 1440p High result of 41 FPS, which suggests that users targeting 4K should prioritize lowering the preset over lowering the resolution, as the pixel count is less punishing than the shader complexity when the GPU is this constrained.

CPU Role

The Intel Core Ultra 7 155H is a 16-core, 22-thread processor with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. Its architecture is Meteor Lake, built on a 7 nm process, and it features 24 MB of shared L3 cache. In the context of Microsoft Flight Simulator, which is known for its heavy single-threaded simulation logic, the boost clock of 4.80 GHz is the more relevant specification for maintaining high frame rates at lower resolutions.

The CPU's benchmark scores put it in the 83rd percentile of all CPUs, with an average benchmark score of 32697. Its nearest rivals include the Intel Core i5-14600T, which scores 32707 (a delta of 0%), and the AMD Ryzen AI 7 PRO 360, which scores 32662 (a delta of 0.1%). These are essentially statistical ties, meaning the 155H is well within the expected performance band for a modern mobile processor. The Cinebench R23 multi-core score of 15028 and single-core score of 1743 indicate that the CPU has enough raw throughput to feed the GPU in most scenarios.

In the measured FPS data, the CPU's role becomes apparent when comparing the scaling from 1080p to 1440p. At Low settings, the drop from 88 FPS to 71 FPS is a 19% reduction, which is less than the 41% reduction seen from 1440p to 4K. This suggests that at 1080p, the CPU is still able to keep up with the GPU's demands, and the frame rate is more limited by the graphics card's ability to render the scene. If the CPU were the bottleneck, we would expect the FPS to remain relatively flat as resolution decreases, but instead we see a clear GPU-bound trend.

However, the 22 threads and 16 cores are not wasted in this title. Flight simulators often have background tasks such as terrain streaming, AI traffic, and physics calculations that can leverage multiple cores. The 155H's multi-threaded performance, as evidenced by its Passmark multi-thread score of 24873, ensures that these background processes do not introduce stutter or frame drops. The 2 MB per-core L2 cache and 112 KB per-core L1 cache also help with the rapid data access needed for the game's complex world rendering.

The data shows that the CPU is not the limiting factor in any of the measured configurations. Even at 1080p Low, where the GPU is producing 88 FPS, the CPU is able to maintain that frame rate without dropping below the GPU's output. This is a good sign for users who might want to upgrade the GPU in the future, as the 155H would likely be able to support a faster graphics card without becoming a bottleneck.

Settings Recommendations

The measured FPS data provides clear guidance on which settings preset offers the best experience for this hardware combination. At 1920x1080, the High preset delivers 51 FPS, which is playable but not ideal for a simulator where smoothness is critical. The Medium preset, at 68 FPS with a minimum of 58 FPS, offers a significantly better experience, with the additional headroom ensuring that even complex scenes with dense cloud cover or detailed airports will not cause the frame rate to dip below 60 FPS.

For users with 2560x1440 monitors, the Medium preset is the clear choice. The 55 FPS average with a 47 FPS minimum is acceptable, though it may require slight tuning of individual settings to achieve a more consistent 60 FPS. The Low preset at 1440p delivers 71 FPS, which is smooth but sacrifices too much visual fidelity for a game that is celebrated for its graphics. The High preset at 1440p, at 41 FPS, is too choppy for a pleasant experience, and the Ultra preset at 39 FPS is even worse.

At 3840x2160, the situation is more challenging. The Low preset at 52 FPS is the only playable option, and even then, users may need to accept some visual compromises. The Medium preset at 41 FPS is borderline, with a minimum of 35 FPS that could cause noticeable stutter during heavy load. The High and Ultra presets, at 31 FPS and 29 FPS respectively, are not recommended for serious play, as the low frame rates make precise control difficult.

The Medium preset is the sweet spot across all resolutions in terms of balancing visual quality and performance. It provides the only min/max FPS data in the pack, which indicates that the testers found it to be a stable configuration worth measuring in detail. The data shows that at Medium settings, the system is able to maintain a reasonable frame rate at all three resolutions, with the 4K result of 41 FPS being the only one that falls below the 60 FPS target. For users who prioritize smoothness over visual fidelity, the Low preset is a viable alternative, particularly at 1440p and 4K.

How This Combo Ranks

The Intel Core Ultra 7 155H and NVIDIA GeForce RTX 5050 combination ranks 2394 out of 2996 tested combos for Microsoft Flight Simulator. This places it in the bottom 20% of all configurations, which is a low ranking for a system that features a 2023 CPU and a 2025 GPU. The ranking suggests that while the individual components are capable in isolation, the combination is not well-suited for this particular game's demands.

The GPU's percentile ranking is 66th among all GPUs, with an average benchmark score of 21035. Its nearest rivals include the AMD Radeon RX Vega M GL, which scores 21153 (a delta of -0.6%), and the AMD Radeon HD 8970M, which scores 21237 (a delta of -1%). These are older, less capable cards, which is surprising given that the RTX 5050 is a current-generation product. The fact that the RTX 5050 is statistically tied with these older cards in average benchmark score explains why the combo ranks so low; the GPU is not performing at a level that would push the system higher in the rankings.

The CPU's percentile ranking of 83rd is much better, but it is not enough to compensate for the GPU's limitations. The 155H's average benchmark score of 32697 puts it in the top 17% of all CPUs, but in a game like Microsoft Flight Simulator, the GPU is the dominant factor in determining overall performance. The combo rank of 2394 out of 2996 indicates that there are 602 tested configurations that perform worse, but there are also a significant number of systems with better GPU performance that achieve higher rankings.

The data suggests that this combo is better suited for other types of games or workloads where the CPU's strengths can be more fully utilized. In Microsoft Flight Simulator, the RTX 5050's 8 GB of VRAM and 320.0 GB/s of memory bandwidth are simply not enough to handle the game's high-resolution textures and complex shaders at higher settings. The low combo rank is a reflection of this mismatch between the CPU's capabilities and the GPU's limitations.

GPU Role

The NVIDIA GeForce RTX 5050 is built on the Blackwell 2.0 architecture, with a chip size of 149 mm² and 16,900 million transistors. It has a base clock of 2317 MHz and a boost clock of 2572 MHz, with 8 GB of GDDR6 memory on a 128-bit bus providing 320.0 GB/s of bandwidth. The GPU has 2560 shading units, 80 TMUs, and 32 ROPs, along with 20 ray tracing cores and 80 tensor cores.

In Microsoft Flight Simulator, the GPU's role is to render the vast, detailed world, including terrain, buildings, aircraft, and weather effects. The game's reliance on high-resolution textures and complex lighting means that the RTX 5050's 8 GB of VRAM is quickly consumed at higher resolutions and settings. The 128-bit memory bus and 320.0 GB/s bandwidth are also limiting factors, as the game needs to stream large amounts of texture data from memory to the GPU.

The GPU's benchmark scores provide context for its in-game performance. Its Passmark G3D score is 17326, and its 3DMark Steel Nomad DX12 score is 2502. The Geekbench OpenCL score of 90334 and Vulkan score of 89381 indicate that the GPU is capable of handling modern APIs, but its raw compute power is limited. The FP32 performance of 13.17 TFLOPS is modest for a current-generation card, which explains why it struggles at 4K resolutions.

The GPU's average benchmark score of 21035 places it in the 66th percentile, with nearest rivals including the AMD Radeon RX Vega M GL (21153, -0.6%) and the NVIDIA RTX A4000 Mobile (21379, -1.6%). These comparisons show that the RTX 5050 is not a high-end part; it is positioned as a mainstream mobile GPU. In Microsoft Flight Simulator, this means that users must be willing to compromise on settings to achieve playable frame rates.

The measured FPS data shows that the GPU's performance is heavily influenced by the preset level. The jump from Low to Medium at 1080p results in a 23% FPS drop (from 88 to 68), while the jump from Medium to High results in a 25% FPS drop (from 68 to 51). The jump from High to Ultra is smaller, at 4% (from 51 to 49), suggesting that the Ultra preset's additional effects are not as demanding as the step from Medium to High. This pattern is consistent across all resolutions, indicating that the GPU's shading units and texture units are the primary bottleneck, rather than memory bandwidth or VRAM capacity.

Measured FPS Breakdown

At 1920x1080, the system delivers 88 FPS at Low settings, 68 FPS at Medium (with a minimum of 58 FPS and maximum of 78 FPS), 51 FPS at High, and 49 FPS at Ultra. The 1080p results show that the system is capable of exceeding 60 FPS at Low settings, and the Medium preset's 68 FPS average is a good target for a smooth experience. The High preset's 51 FPS is playable but may have occasional dips below 50 FPS during complex scenes, while the Ultra preset's 49 FPS is very close to the High result, suggesting that the Ultra preset's additional effects are not well-optimized for this GPU.

At 2560x1440, the system manages 71 FPS at Low settings, 55 FPS at Medium (with a minimum of 47 FPS and maximum of 63 FPS), 41 FPS at High, and 39 FPS at Ultra. The 1440p results show a clear step down from 1080p, with the Low preset being the only one that maintains a 60+ FPS average. The Medium preset's 55 FPS is acceptable, but the 47 FPS minimum indicates that there will be noticeable frame drops in demanding scenarios. The High and Ultra presets, at 41 FPS and 39 FPS respectively, are not recommended for serious play.

At 3840x2160, the system produces 52 FPS at Low settings, 41 FPS at Medium (with a minimum of 35 FPS and maximum of 47 FPS), 31 FPS at High, and 29 FPS at Ultra. The 4K results show that the system is only viable at Low settings, where the 52 FPS average is just above the 50 FPS threshold for playability. The Medium preset's 41 FPS is borderline, with a 35 FPS minimum that could cause stutter during takeoff or landing. The High and Ultra presets, at 31 FPS and 29 FPS respectively, are not recommended, as the low frame rates make the simulation feel sluggish and unresponsive.

The data shows a consistent pattern across all resolutions: the Medium preset offers the best balance of visual quality and performance, while the Low preset is the fallback for users who prioritize frame rate above all else. The High and Ultra presets are only suitable for users who are willing to accept sub-60 FPS performance in exchange for maximum visual fidelity. The min/max FPS data for the Medium preset at all three resolutions provides confidence that the frame pacing is stable, with the range between minimum and maximum staying within 10-12 FPS, which is a positive indicator for a smooth experience.
