Microsoft Flight Simulator

# Microsoft Flight Simulator: Intel Core i5-12400F + NVIDIA GeForce RTX 4070

This combination pairs a 6-core, 12-thread Alder Lake processor with an Ada Lovelace GPU that carries 12 GB of GDDR6X memory across a 192-bit bus. The benchmark data for this specific rig shows a system that is clearly capable of running Microsoft Flight Simulator at all tested settings, but the scaling patterns reveal where the bottlenecks truly lie. The measured frame rates suggest this is a pairing where the GPU's raw throughput and memory bandwidth are the primary drivers of performance, while the CPU's 4.40 GHz boost clock and 18 MB of shared L3 cache handle the simulation's demanding single-threaded workloads without becoming the limiting factor in most scenarios.

Resolution Scaling

The frame rate progression from 1920x1080 to 3840x2160 reveals a classic GPU-bound scaling curve, but with some notable non-linearities that hint at the simulation's unique rendering demands. At High settings, the system delivers 97.2 FPS at 1080p, drops to 78.1 FPS at 1440p, and then falls to 55.8 FPS at 4K — a performance retention of 57.4% when moving from 1080p to 4K. This is a substantial drop, but it is not the steep cliff seen in purely rasterized games; flight simulation with its complex terrain streaming and weather systems tends to stress both CPU and GPU simultaneously.

The Low preset tells a more interesting story. At 1080p Low, the system hits 162.4 FPS, which is 67.1% higher than the High preset at the same resolution. At 1440p Low, it maintains 130.5 FPS, and even at 4K Low it holds 97 FPS. The scaling from 1080p to 4K at Low settings shows a 40.3% drop, which is actually less severe than the High preset's 42.6% drop. This suggests that at lower settings, where the GPU has less geometry and shading work, the CPU's 6 cores and 12 threads can keep the simulation logic fed, and the GPU's 2475 MHz boost clock can still produce high frame rates even at 4K.

The Medium and Ultra presets show the expected hierarchy: Medium at 4K (75.4 FPS) is closer to High (55.8 FPS) than to Low (97 FPS), while Ultra at 4K (52 FPS) is the most demanding configuration tested. The gap between Ultra and High at 4K is a mere 6.8% (52 vs 55.8 FPS), which indicates that the Ultra preset's additional effects are not dramatically heavier than High — or that the system is hitting a performance ceiling where additional detail settings have diminishing returns. The 1440p data reinforces this: Ultra (74.5 FPS) is only 4.6% slower than High (78.1 FPS), while Medium (102 FPS) sits 30.6% above Ultra.

GPU Role

The NVIDIA GeForce RTX 4070 is the undisputed performance driver in this pairing, and its specifications explain why. With 5888 shading units, 184 texture mapping units, and 64 ROPs, the GPU has substantial raw compute for the simulator's rendering pipeline. The 12 GB of GDDR6X memory operating at 21 Gbps effective delivers 504.2 GB/s of bandwidth, which is critical for Microsoft Flight Simulator's extensive texture streaming — the game loads high-resolution satellite imagery and terrain data continuously, and memory bandwidth directly impacts how quickly these assets can be fed to the renderer.

The GPU's boost clock of 2475 MHz (base 1920 MHz) allows the Ada Lovelace architecture to maintain high utilization across all resolutions. The data shows that the GPU is the primary bottleneck at 4K: the frame rate drops from 97 FPS at Low to 52 FPS at Ultra, a 46.4% reduction that correlates strongly with the increased shading and texture work. The RTX 4070's 46 RT cores and 184 tensor cores are present but not explicitly stressed in this data; the measured FPS values likely reflect traditional rasterization performance rather than ray-traced or DLSS-enhanced workloads, as no such settings are indicated in the measured rows.

At 1080p, the GPU still has headroom — the 162.4 FPS at Low suggests that the CPU may become a secondary constraint at very high frame rates. However, the 92.7 FPS at 1080p Ultra shows that even at the highest settings, the RTX 4070 can comfortably drive a high-refresh 1080p display. The 4K results are more telling: the GPU's 504.2 GB/s bandwidth and 29.15 TFLOPS of FP32 compute are sufficient for playable frame rates (55.8 FPS High, 52 FPS Ultra), but the system clearly favors 1440p as the sweet spot for this simulator.

CPU Role

The Intel Core i5-12400F brings 6 Physical cores and 12 threads with a 2.50 GHz base clock and 4.40 GHz boost clock. Its Alder Lake architecture on a 10 nm process provides strong single-threaded performance, which is essential for a flight simulator that must process flight dynamics, weather systems, and AI air traffic in real-time. The CPU's Cinebench R23 scores — 16518 multicore and 2332 singlecore — indicate a balanced processor that can handle both the simulation logic and the game's rendering thread overhead.

The benchmark data shows that the CPU is rarely the limiting factor in this pairing. At 1080p Low, the system achieves 162.4 FPS, which is high enough that the CPU's 12 threads must be keeping up with the GPU's frame generation. The CPU's 18 MB of shared L3 cache helps with the simulator's large working set, and its dual-channel DDR4/DDR5 memory support (the pack does not specify which is used) provides adequate bandwidth for feeding the GPU. The 3dmark single-thread score of 909 and 2-thread score of 1699 suggest that the CPU's integer and floating-point capabilities are well-matched to the simulation's demands.

However, the CPU does show its limits at 1080p High and Ultra. The gap between 1080p Low (162.4 FPS) and 1080p High (97.2 FPS) is 40.1%, which is larger than the gap between 4K Low (97 FPS) and 4K High (55.8 FPS) at 42.6% — but the absolute numbers at 1080p High (97.2 FPS) are still respectable. The CPU's PassMark single-thread score of 3481 and 2-thread score of 3481 (the same value, indicating a single-thread bottleneck in that test) suggest that the simulator's main thread is well-served by the 4.40 GHz boost clock. The CPU's percentile rank of 77 vs all CPUs places it above average, but not in the top tier — this is consistent with a mid-range processor that can handle the simulator without being the primary constraint at 1440p and 4K.

Measured FPS Breakdown

At 1920x1080, the system delivers a wide range of performance depending on settings. Low produces 162.4 FPS, which is the highest measured frame rate in the entire dataset. Medium drops to 127.7 FPS, High to 97.2 FPS, and Ultra to 92.7 FPS. The step from Low to Medium is a 21.4% reduction, while the step from Medium to High is 23.9%, and from High to Ultra is only 4.6%. This suggests that the Ultra preset's additional settings (likely higher draw distances, more detailed shadows, and enhanced effects) have a modest impact on frame rate at 1080p — the GPU has enough headroom to absorb the extra load.

At 2560x1440, the frame rates are still solid. Low produces 130.5 FPS, Medium 102 FPS, High 78.1 FPS, and Ultra 74.5 FPS. The scaling from 1080p to 1440p at each setting shows a consistent drop: Low drops 19.7%, Medium drops 20.1%, High drops 19.7%, and Ultra drops 19.6%. This uniformity indicates that the GPU is scaling predictably with pixel count, and the CPU is not introducing additional bottlenecks at this resolution.

At 3840x2160, the system remains playable but the frame rates drop noticeably. Low produces 97 FPS, Medium 75.4 FPS, High 55.8 FPS, and Ultra 52 FPS. The scaling from 1440p to 4K shows larger drops: Low drops 25.7%, Medium drops 26.1%, High drops 28.6%, and Ultra drops 30.2%. The increasing percentage drops at higher settings suggest that the GPU's memory bandwidth (504.2 GB/s) becomes more constrained as resolution and detail increase, with the Ultra setting at 4K dropping to 52 FPS — a 46.4% reduction from the 4K Low result.

Settings Recommendations

Based on the measured FPS data, the Medium preset at 2560x1440 offers the most compelling experience for this combo. At 102 FPS, it provides a 30.6% improvement over High settings (78.1 FPS) while still delivering a visually detailed image that takes advantage of the RTX 4070's capabilities. For users who prioritize visual fidelity, the High preset at 1440p (78.1 FPS) is the best choice, as it maintains a comfortable frame rate while offering more detail than Medium.

At 1920x1080, the Ultra preset (92.7 FPS) is fully playable and provides the highest visual quality at that resolution. The gap between High (97.2 FPS) and Ultra (92.7 FPS) is only 4.6%, so the Ultra preset is worth the small performance cost for users with 1080p displays. At 4K, the Medium preset (75.4 FPS) is the recommended choice — it provides a smooth experience above 60 FPS, whereas High (55.8 FPS) and Ultra (52 FPS) fall below that threshold. The Low preset at 4K (97 FPS) is an option for users who prioritize frame rate above all else, but the visual compromise is significant given the simulator's focus on scenery detail.

For users with a 1440p display, the data clearly shows that Medium (102 FPS) is the sweet spot — it offers a 30.6% performance headroom over High, which can be useful for maintaining consistent frame rates in dense urban areas or during weather-heavy flights. The Ultra preset at 1440p (74.5 FPS) is also viable, but the 4.6% difference from High suggests that the extra settings are not worth the performance cost unless the user is particularly sensitive to visual quality. Overall, this combo is best utilized at 1440p Medium or High, with 4K Medium as a viable alternative for users who prefer higher resolutions.
