Microsoft Flight Simulator

# Microsoft Flight Simulator — Intel Core i5-12400 + NVIDIA GeForce RTX 5080

The data for this combination shows a system that scales predictably across resolutions and settings, with the RTX 5080 carrying most of the load at higher resolutions while the i5-12400 becomes a limiting factor at 1080p. The combo ranks 82nd out of 1,795 tested configurations, placing it in the top 4.6% of all tested systems for this flight simulator. The measured frame rates range from 72.6 FPS at 4K Ultra to 181.3 FPS at 1080p Low, indicating a wide operational envelope that covers everything from high-fidelity cockpit views to fast-moving ground traffic.

Resolution Scaling

The FPS drop from 1080p to 4K is steep but consistent across settings, revealing where the bottleneck shifts. At Low settings, the average frame rate falls from 181.3 FPS at 1080p to 171.1 FPS at 1440p, then to 130.5 FPS at 4K — a 28% reduction from 1080p to 4K. This relatively modest decline at Low suggests the CPU is holding performance back even at lower resolutions, as the RTX 5080 has ample headroom to render simple scenes quickly.

At Medium settings, the scaling pattern changes. The system delivers 167.8 FPS at 1080p, drops to 136.8 FPS at 1440p, and then to 103.4 FPS at 4K. The 4K figure represents a 38% reduction from 1080p, showing the GPU beginning to take on more work as scene complexity increases. High settings follow a similar trajectory: 130.3 FPS at 1080p, 105.8 FPS at 1440p, and 78 FPS at 4K — a 40% drop across the full resolution range.

Ultra settings produce the largest absolute decline, with 125 FPS at 1080p falling to 98.6 FPS at 1440p and finally 72.6 FPS at 4K. This 42% reduction from 1080p to 4K indicates that at Ultra, the GPU is the primary limiting component, with the pixel throughput requirements of 4K outstripping the RTX 5080's capacity at maximum quality presets. The data shows that the gap between settings narrows as resolution increases — at 1080p, Ultra is 31% slower than Low, but at 4K that difference grows to 44%, confirming that higher resolutions amplify the cost of quality settings.

GPU Role

The RTX 5080's specifications explain much of its behavior in this title. With 16 GB of GDDR7 memory on a 256-bit bus delivering 960.0 GB/s of bandwidth, the card has sufficient memory capacity and throughput for Microsoft Flight Simulator's large texture sets and streaming terrain data. The boost clock of 2617 MHz, combined with 10,752 shading units and 112 ROPs, provides the raw computational power needed for the simulator's complex rendering workloads.

The GPU's percentile ranking of 89 against all graphics cards places it well above average, and its average benchmark score of 59,188 reflects strong general-purpose performance. However, the nearest rivals in the aggregate benchmark data — the Intel Arc A570M at a 1.6% delta, the Intel Arc Pro A60 at -1.9%, and the Intel Arc A580 at 2.5% — are all significantly less powerful cards, suggesting that the RTX 5080's specialized features (84 RT cores, 336 tensor cores, DirectX 12 Ultimate support) may not be fully leveraged by this flight simulator's rendering engine.

The 4K Ultra result of 72.6 FPS indicates that the GPU is working near its limits at maximum quality, while the 4K Low result of 130.5 FPS shows that even at reduced settings, the card maintains high throughput. The memory clock of 1875 MHz (30 Gbps effective) and the 960.0 GB/s bandwidth are critical for streaming the vast geographical data that Microsoft Flight Simulator loads continuously, and the data suggests that memory bandwidth is not a bottleneck at any tested resolution or setting combination.

Settings Recommendations

The measured data provides clear guidance on the optimal settings balance. At 1080p, Medium settings deliver 167.8 FPS, which is only 7% slower than Low but substantially faster than High (130.3 FPS) and Ultra (125 FPS). The jump from Medium to High costs 37.5 FPS at 1080p, while the jump from High to Ultra costs only 5.3 FPS — suggesting that High is the sweet spot for visual quality at this resolution if frame rate is a priority.

At 1440p, Medium produces 136.8 FPS, which is 30% faster than High's 105.8 FPS and 39% faster than Ultra's 98.6 FPS. The difference between High and Ultra at 1440p is only 7.2 FPS, making High the more sensible choice when seeking the best balance of image quality and smoothness. For 4K, Medium's 103.4 FPS is notably smoother than High's 78 FPS and Ultra's 72.6 FPS, though the visual fidelity loss may be noticeable in cockpit details and distant scenery.

Across all resolutions, the data shows that Medium provides the most consistent frame rates relative to the quality settings above it. At 4K, Medium is 25% faster than High and 30% faster than Ultra; at 1440p, those margins are 29% and 39%; at 1080p, they are 29% and 38%. The recommendation from the measured rows is to prioritize Medium at 4K, High at 1440p, and either High or Ultra at 1080p depending on whether frame rate or maximum visual fidelity is preferred.

How This Combo Ranks

The combination of the Intel Core i5-12400 and NVIDIA GeForce RTX 5080 achieves a rank of 82 out of 1,795 tested combos in Microsoft Flight Simulator, placing it in the top 4.6% of all configurations. This strong ranking is driven primarily by the GPU, which sits in the 89th percentile among all graphics cards, while the CPU's 77th percentile ranking among all processors is comparatively modest.

The CPU's nearest rivals in aggregate benchmark scores are the Intel Core i7-9700 (0.1% delta), Intel Core i7-8700 (-0.2%), AMD Ryzen Threadripper PRO 5995WX (-0.4%), and Intel Core i5-11600K (0.4%). These scores indicate that the i5-12400 performs nearly identically to the older i7 parts and even the Threadripper PRO in general benchmarks, which is notable given the i5's 6-core, 12-thread configuration.

The GPU's nearest rivals in aggregate scores are the Intel Arc A570M (1.6% delta), Intel Arc Pro A60 (-1.9%), Intel Arc A580 (2.5%), and AMD Radeon Pro W5500X (2.6%). The RTX 5080's average benchmark score of 59,188 versus the Arc A580's 57,756 shows a 2.5% advantage, yet in actual flight simulator performance, the RTX 5080's 16 GB of VRAM and 960.0 GB/s bandwidth likely provide a larger real-world margin than the aggregate scores suggest.

CPU Role

The Intel Core i5-12400 brings 6 cores and 12 threads with a base clock of 2.50 GHz and a boost clock of 4.40 GHz, drawing 65 W TDP. Its 18 MB of shared L3 cache and 1.25 MB L2 per core provide reasonable data locality for the simulator's draw calls and physics calculations. The CPU's single-thread performance is solid, with a 3DMark single-thread score of 910 and a Cinebench R23 single-core score of 2,249, which is important for a flight simulator that often relies on a primary simulation thread.

The multi-threaded scores are competitive for a 6-core part: Cinebench R23 multicore reaches 15,935, while 3DMark max-threads hits 5,890. The PassMark multithread score of 18,747 and physics score of 1,105 indicate that the CPU can handle the background tasks of terrain streaming and AI traffic without collapsing, though the data suggests it becomes a constraint at lower resolutions.

Evidence of CPU limitation appears in the 1080p results. At Low settings, the system produces 181.3 FPS, but at 1440p Low it only drops to 171.1 FPS — a mere 5.6% decline for a 78% increase in pixel count. This relative flatness across resolutions at Low settings indicates that the CPU is the primary limiter at 1080p Low, preventing the GPU from reaching its full frame-rate ceiling. Similarly, the 1080p Medium result of 167.8 FPS versus the 1440p Medium of 136.8 FPS shows a 22.6% drop, which is more in line with GPU-bound scaling.

The CPU's benchmark percentile of 77 and average score of 19,850 place it just above the Core i7-9700 (19,831) and just below the Core i7-8700 (19,894), confirming that this mid-range 12th-gen part delivers last-generation high-end performance. For Microsoft Flight Simulator specifically, the 6-core/12-thread configuration appears adequate for maintaining 100+ FPS at 1440p Medium, but the data shows that users seeking maximum frame rates at 1080p would benefit from a higher-clocked or higher-core-count processor.

Measured FPS Breakdown

At 3840x2160 (4K), the system delivers 130.5 FPS at Low settings, 103.4 FPS at Medium, 78 FPS at High, and 72.6 FPS at Ultra. The progression from Low to Ultra represents a 44% performance reduction, with the largest single-step drop occurring between Medium and High (24.6% slower).

At 2560x1440, the results are 171.1 FPS at Low, 136.8 FPS at Medium, 105.8 FPS at High, and 98.6 FPS at Ultra. The Low-to-Ultra gap here is 42%, slightly narrower than at 4K, and the step from Medium to High costs 31 FPS (22.7%).

At 1920x1080, the system achieves 181.3 FPS at Low, 167.8 FPS at Medium, 130.3 FPS at High, and 125 FPS at Ultra. This resolution shows the smallest relative spread between settings (31% from Low to Ultra), and notably, the difference between High and Ultra is just 5.3 FPS, making Ultra the better choice at 1080p if visual quality is the priority.

The data shows that frame rates remain above 70 FPS in every tested configuration, with only the 4K Ultra and 4K High settings falling below 80 FPS. For smooth flight simulation, all measured configurations provide playable performance, but the 4K Ultra result of 72.6 FPS is the only setting where the system dips close to the 60 FPS threshold that many users consider the minimum for comfortable play.
