Microsoft Flight Simulator

# CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core Ultra 5 135H is a 14-core, 18-thread mobile processor built on Intel's Meteor Lake architecture using a 7 nm process node. Its base clock of 3.60 GHz and boost clock of 4.60 GHz place it in the upper tier of mobile CPUs, with 18 MB of shared L3 cache and a dual-channel DDR5 memory interface delivering 89.6 GB/s of bandwidth. The chip sits at the 81st percentile among all CPUs tested on this benchmark database, indicating that its overall computational performance outpaces roughly four-fifths of the processors tracked.

In the context of Microsoft Flight Simulator, the CPU's role is substantial because the simulation engine must continuously process flight physics, weather systems, terrain streaming, and AI traffic. The benchmark data shows that the CPU's multi-threaded capabilities are strong but not exceptional. Its Cinebench R23 multi-core score of 11875.5 and single-core score of 1700 demonstrate balanced performance, with the single-core result being particularly relevant for the game's primary simulation thread. The PassMark single-thread score of 3521 confirms that the chip can handle the frame-to-frame logic demands that Flight Simulator imposes.

Comparing the CPU to its nearest rivals in the benchmark database provides context for its positioning. The AMD Ryzen 7 5800X scores 29123 on average, which is only 0.1% higher than the Core Ultra 5 135H's average benchmark score of 29093. This near-parity with a desktop-class processor from a previous generation underscores that the mobile chip's performance envelope is competitive. The Intel Xeon Phi 7210 scores 29245, a 0.5% gap, while the AMD Ryzen 5 5600XT scores 28940, putting the Core Ultra 5 135H 0.5% ahead. The Intel Core i5-13500HX scores 29270, making it 0.6% faster on average. These deltas are all within a single percentage point, meaning that in synthetic workloads, the Core Ultra 5 135H is statistically indistinguishable from these alternatives.

For Flight Simulator specifically, the CPU's 14 cores and 18 threads provide ample parallelism for background tasks like scenery loading and AI traffic updates, while the 4.60 GHz boost clock ensures that the main simulation loop receives adequate single-thread performance. The data suggests that at lower resolutions and higher settings, where the GPU becomes less of a bottleneck, the CPU's contribution to frame rates will be more pronounced. The measured FPS at 1080p Low of 106 FPS versus 4K Low of 63 FPS indicates that the CPU maintains consistent performance across resolutions, as the frame rate drop is primarily attributable to GPU load rather than CPU limitations.

# GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4060 Mobile is built on the Ada Lovelace architecture using TSMC's 5 nm process node, with a chip size of 159 mm² containing 18,900 million transistors. The GPU operates at a base clock of 1545 MHz and boosts to 1890 MHz, with 8 GB of GDDR6 memory on a 128-bit bus delivering 256.0 GB/s of bandwidth. Its 3072 shading units, 96 texture mapping units, and 48 raster output processors are complemented by 24 RT cores and 96 tensor cores, enabling DirectX 12 Ultimate feature support. The FP32 throughput of 11.61 TFLOPS positions this as a mid-range mobile GPU, and its PassMark G3D score of 17469 places it at the 67th percentile among all GPUs tracked.

The GPU's nearest rivals in the database show a tightly clustered competitive set. The NVIDIA GeForce RTX 2080 scores 22895 on average, which is 0.7% higher than the RTX 4060 Mobile's average benchmark score of 22729. The AMD Radeon RX 7700 XT scores 22549, placing it 0.8% lower, while the Intel Arc B580 scores 23021, putting it 1.3% ahead. The NVIDIA GeForce RTX 5060 Mobile scores 22435, making it 1.3% slower. These sub-1.5% deltas indicate that the RTX 4060 Mobile delivers performance on par with these desktop and newer mobile alternatives, despite its relatively modest 115 W TDP.

In Microsoft Flight Simulator, the GPU's role is primarily concerned with rendering dense terrain, complex aircraft models, and atmospheric effects. The 8 GB VRAM capacity is adequate for the game's textures at 1080p and 1440p, but at 4K with Ultra settings, the VRAM and memory bandwidth may become limiting factors. The measured FPS data illustrates this: at 4K Ultra, the average frame rate drops to 35 FPS, while at 4K Low it reaches 63 FPS. This 28 FPS spread across settings at the same resolution highlights how the GPU's rendering load impacts performance more than the CPU at higher resolutions.

The GPU's memory clock of 2000 MHz with 16 Gbps effective speed provides 256.0 GB/s of bandwidth, which is sufficient for the game's streaming requirements but not excessive. The pixel rate of 90.72 GPixel/s and texture rate of 181.4 GTexel/s indicate that the GPU can handle the fill-rate demands of high-resolution rendering, though the 128-bit memory bus constrains memory-bound scenarios. The data shows that the RTX 4060 Mobile is the primary bottleneck at 4K, as frame rates scale more dramatically with settings changes at that resolution compared to 1080p.

# Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data provides a clear picture of how resolution scaling affects performance for this CPU-GPU combination in Microsoft Flight Simulator. At 1080p Low, the average frame rate is 106 FPS. Moving to 1440p Low reduces this to 86 FPS, a drop of 20 FPS or 18.9%. At 4K Low, the average falls to 63 FPS, which is 43 FPS lower than 1080p Low, representing a 40.6% reduction. This scaling pattern indicates that the GPU becomes increasingly dominant as a limiting factor when resolution increases, but the CPU still provides a solid foundation at lower resolutions.

The Medium settings row provides the most complete data, with both minimum and maximum FPS recorded. At 1080p Medium, the average is 83 FPS with a minimum of 70 FPS and maximum of 95 FPS. At 1440p Medium, the average drops to 67 FPS, with minimum and maximum of 57 FPS and 77 FPS respectively. At 4K Medium, the average falls to 49 FPS, with a minimum of 42 FPS and maximum of 57 FPS. The minimum-to-maximum spread of 25 FPS at 1080p Medium expands to 20 FPS at 1440p Medium and 15 FPS at 4K Medium, suggesting that frame time consistency improves slightly at higher resolutions, likely because the GPU's consistent workload smooths out CPU-induced variability.

For High settings, the scaling from 1080p to 1440p shows a drop from 62 FPS to 50 FPS, a 19.4% reduction. From 1440p High to 4K High, the drop is from 50 FPS to 37 FPS, a 26.0% reduction. The Ultra settings row shows the most severe scaling: 1080p Ultra averages 59 FPS, 1440p Ultra averages 48 FPS (18.6% drop), and 4K Ultra averages 35 FPS (27.1% drop from 1440p). These percentage reductions are relatively consistent across settings, indicating that the GPU's performance scaling with resolution follows a predictable pattern.

The data reveals that the CPU is not a significant bottleneck at any resolution, as the frame rate differences between 1080p and 1440p are proportionally similar to those between 1440p and 4K. If the CPU were limiting performance, we would expect the frame rate to remain relatively flat as resolution increases, particularly at lower settings where the GPU load is lighter. Instead, the consistent 20-40% drops across each resolution step demonstrate that the RTX 4060 Mobile is the primary constraint, with its rendering workload scaling directly with pixel count and settings complexity.

# Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the Medium preset at 1080p offers the most balanced experience for this hardware combination, delivering an average of 83 FPS with a minimum of 70 FPS. This frame rate ensures smooth gameplay in a flight simulator where sudden drops can be jarring, and the 70 FPS minimum keeps the experience above the 60 FPS threshold that most players consider acceptable. The Medium preset at 1440p, with an average of 67 FPS and minimum of 57 FPS, is also viable for users with 1440p displays, though the minimum dips below 60 FPS.

For users prioritizing visual fidelity over frame rate, the High preset at 1080p provides an average of 62 FPS, which is playable but leaves little headroom for complex scenes with dense clouds or detailed airports. The Ultra preset at 1080p averages 59 FPS, which is marginally below the 60 FPS target and may result in noticeable stuttering during demanding sequences. At 1440p, the High preset's 50 FPS average is acceptable for a simulation genre where 30 FPS is often considered playable, but the Medium preset's 67 FPS offers a safer margin.

The Low preset at any resolution provides the highest frame rates, with 106 FPS at 1080p, 86 FPS at 1440p, and 63 FPS at 4K. However, Low settings in Microsoft Flight Simulator significantly reduce the visual quality of terrain textures, aircraft models, and atmospheric effects, which detracts from the core experience of the sim. The data suggests that Medium settings at 1440p or High settings at 1080p represent the sweet spot, depending on whether the user prioritizes resolution or visual effects.

For 4K displays, the data indicates that only the Low preset achieves an average above 60 FPS, while Medium averages 49 FPS and High/Ultra fall to 37 FPS and 35 FPS respectively. Users with 4K displays should consider using Medium settings with a frame rate cap at 48 FPS to maintain consistency, or accept the visual trade-offs of Low settings for smoother performance. The measured minimum FPS values for Medium settings at 4K (42 FPS) show that frame times can spike, so users should be prepared for occasional stutters even at this moderate preset.

# Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the benchmark results show a clear progression across settings. Low settings achieve the highest average at 106 FPS, followed by Medium at 83 FPS with a minimum of 70 FPS and maximum of 95 FPS. High settings produce 62 FPS average, and Ultra settings produce 59 FPS average. The spread between Low and Ultra at 1080p is 47 FPS, indicating that the GPU has substantial headroom at this resolution to accommodate higher visual fidelity.

At 2560x1440, the performance scaling follows a similar pattern but with reduced margins. Low settings average 86 FPS, Medium averages 67 FPS with a minimum of 57 FPS and maximum of 77 FPS, High averages 50 FPS, and Ultra averages 48 FPS. The difference between High and Ultra at 1440p is only 2 FPS, suggesting that the Ultra preset's additional effects have minimal impact on this resolution, possibly due to other bottlenecks. The gap between Low and Ultra narrows to 38 FPS at this resolution.

At 3840x2160, the GPU becomes the dominant constraint. Low settings average 63 FPS, Medium averages 49 FPS with a minimum of 42 FPS and maximum of 57 FPS, High averages 37 FPS, and Ultra averages 35 FPS. The spread between Low and Ultra at 4K is 28 FPS, which is the smallest of all three resolutions, confirming that the GPU's rendering capacity is nearly exhausted at this resolution. The Medium settings data at 4K shows a 15 FPS range between minimum and maximum, indicating relatively stable frame delivery.

Across all resolutions, the Medium settings row is the only one with complete minimum and maximum data, providing insight into frame time consistency. At 1080p Medium, the range is 25 FPS; at 1440p Medium, it is 20 FPS; and at 4K Medium, it is 15 FPS. This narrowing range suggests that as the GPU becomes more heavily loaded, frame delivery becomes more consistent, likely because the GPU's workload dominates and reduces CPU-side variations.
