Microsoft Flight Simulator

The Intel Core Ultra 5 245 and NVIDIA GeForce RTX 4070 Ti combination delivers a robust experience in Microsoft Flight Simulator, with performance scaling predictably across resolutions. The measured data indicates that this pairing is well-balanced for high-refresh-rate 1440p gaming and remains playable at 4K, though the GPU becomes the primary constraint as pixel count increases.

Resolution Scaling

The performance trajectory from 1080p to 4K reveals a classic GPU-bound scaling pattern. At 1080p with High settings, the combo produces an average of 113 FPS. Moving to 1440p High reduces this to 91 FPS, a 19.5% drop. The jump to 4K High yields 67 FPS, representing a further 26.4% decline from 1440p. This progressive degradation across resolutions is characteristic of a system where the RTX 4070 Ti is the limiting component, while the Core Ultra 5 245 provides sufficient headroom to avoid becoming a bottleneck.

The Low settings row amplifies this GPU-bound behavior. At 1080p Low, the system reaches 193 FPS, which decreases to 156 FPS at 1440p and 115 FPS at 4K. The relative drops are smaller in percentage terms than at High settings, suggesting that at lower graphical loads, the CPU begins to assert more influence. However, the absolute frame rates remain high enough that the GPU still dictates overall scaling.

Ultra settings show the steepest curve. The system averages 108 FPS at 1080p, 87 FPS at 1440p, and 64 FPS at 4K. The 4K Ultra result is notably only 5 FPS below the 4K High result, indicating that the Ultra preset at 4K is pushing the GPU to its limits where additional settings have diminishing returns on frame rate while still consuming rendering resources.

The Medium preset provides the only rows with measured minimum and maximum frames: at 1080p, 150 average with a 128 minimum and 173 maximum; at 1440p, 121 average with a 103 minimum and 139 maximum; at 4K, 89 average with a 76 minimum and 103 maximum. The variance between minimum and maximum is tighter at higher resolutions, reinforcing that the GPU is consistently saturated at 4K.

The Low preset achieves 193 FPS, which drops to 150 FPS at Medium (with a 128 minimum and 173 maximum), 113 FPS at High, and 108 FPS at Ultra. The gap between High and Ultra is a mere 5 FPS, suggesting that the Ultra preset's additional effects are not heavily taxing at this resolution.

The 2560x1440 results show a more balanced distribution. Low hits 156 FPS, Medium averages 121 FPS (103 minimum, 139 maximum), High averages 91 FPS, and Ultra averages 87 FPS. The High-to-Ultra delta remains small at 4 FPS, indicating that the game's ultra settings primarily affect visual quality rather than raw performance at this resolution.

At 3840x2160, the system's limits become evident. Low produces 115 FPS, Medium averages 89 FPS (76 minimum, 103 maximum), High averages 67 FPS, and Ultra averages 64 FPS. The Ultra preset at 4K is the most demanding configuration tested, with the average frame rate dropping below the 70 FPS threshold that many users consider smooth for flight simulation.

The settings scaling within each resolution is consistent. At 1080p, moving from Low to Ultra costs 85 FPS (193 to 108). At 1440p, the same transition costs 69 FPS (156 to 87). At 4K, it costs 51 FPS (115 to 64). This narrowing delta at higher resolutions is a clear indication of GPU saturation, where the card is already working near its maximum capacity at 4K Low.

Settings Recommendations

For users prioritizing high frame rates at 1080p, the High preset at 113 FPS offers an excellent balance between visual quality and performance. The Ultra preset at 108 FPS provides minimal additional visual benefit for a 5 FPS cost, making High the more sensible choice unless maximum fidelity is desired.

At 1440p, the High preset's 91 FPS is the recommended configuration for most users. It delivers smooth gameplay while maintaining detailed visuals. The Ultra preset at 87 FPS is also viable for those who prefer maximum quality, as the 4 FPS difference is negligible in practice. The Medium preset at 121 FPS is available for users with high-refresh-rate monitors who want to maximize frame rates.

For 4K, the Medium preset at 89 FPS provides the best experience among the tested settings. It offers significantly higher performance than High (67 FPS) or Ultra (64 FPS) while maintaining acceptable visual quality. The Low preset at 115 FPS is suitable for competitive play or users who prioritize frame rate over graphics, but the visual compromise may be too severe for a flight simulator.

The Medium preset is the only configuration with measured minimum frame data across all resolutions, showing consistent performance without severe drops. At 1440p Medium, the 103 FPS minimum ensures no noticeable stuttering. At 4K Medium, the 76 FPS minimum remains above the 60 FPS threshold for smooth gameplay.

CPU Role
