Microsoft Flight Simulator

Microsoft Flight Simulator is notoriously demanding, and this pairing of an Intel Core i5-12400 with a GeForce GTX 1660 Ti lands in a specific performance tier. The data shows this combo ranks 1543rd out of 1795 tested combinations, placing it in the lower third of all systems. That ranking is not a verdict of failure, but it does set expectations: this is a setup for playable, not pristine, flight simulation. The benchmark results indicate that with careful settings management, you can achieve smooth framerates at standard resolutions, but pushing for maximum visual fidelity at 4K will overwhelm the hardware.

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

The Intel Core i5-12400 is a 6-core, 12-thread processor based on the Alder Lake architecture, built on Intel's 10 nm process. It operates with a base clock of 2.50 GHz and a boost clock of 4.40 GHz, drawing a 65 W TDP. Its cache configuration includes 80 KB of L1 per core, 1.25 MB of L2 per core, and a shared 18 MB L3 cache. The CPU supports both DDR4 and DDR5 memory through a dual-channel interface, and it connects via PCIe Gen 5 with 16 lanes. The integrated UHD Graphics 730 is present but irrelevant for this gaming analysis.

In synthetic benchmarks, the i5-12400 shows a strong balance between single-threaded and multi-threaded performance. Its Cinebench R23 scores are 2249 for single-core and 15935 for multi-core, while 3DMark results scale from 910 in single-thread to 5890 in max-threads. The PassMark multi-thread score of 18747 and single-thread score of 3456 confirm this processor is no bottleneck for the GTX 1660 Ti in most scenarios. The CPU's percentile ranking at 77 means it outperforms 77% of all CPUs tested, and its average benchmark score of 19850 places it in close competition with the Intel Core i7-9700 (19831, a 0.1% difference) and Intel Core i7-8700 (19894, a -0.2% difference).

For Microsoft Flight Simulator, the CPU's role is significant because the simulation engine handles vast amounts of world data, physics, and AI traffic. The benchmark data suggests that at lower resolutions and settings, where the GPU is less stressed, the i5-12400's 6 cores and 12 threads are sufficient to keep up. However, the data also shows that the GPU becomes the primary limiter as resolution increases, which is typical for a flight simulator that relies heavily on rendering complex scenery.

FAQ — 4-6 Q&A pairs answerable from FACT PACK data

Q: What is the best average framerate this combo can achieve at 1080p?

A: At 1920x1080 with Low settings, the system reaches an average of 80 FPS. This is the highest recorded framerate across all tested resolutions and settings.

Q: How does the GTX 1660 Ti compare to its nearest rival in performance?

A: The GTX 1660 Ti has an average benchmark score of 13925, which is 0.4% higher than the AMD Radeon RX 570X (13871) and 0.8% higher than both the NVIDIA RTX A2000 Mobile (13821) and the GeForce GTX 680 (13812). It trails the NVIDIA Tesla K10 (14029) by 0.7%.

Q: Can this system handle 4K gaming in Microsoft Flight Simulator?

A: At 3840x2160 with Ultra settings, the average FPS drops to 25.6, which is below the generally accepted threshold for smooth play. Even at High settings, 4K yields only 29.1 FPS. Low settings at 4K produce 48.1 FPS, which is playable but visually compromised.

A: The combination of the Intel Core i5-12400 and NVIDIA GeForce GTX 1660 Ti ranks 1543rd out of 1795 tested system combinations, placing it in the lower 14% of all configurations.

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

The measured FPS data reveals a clear pattern of GPU-bound scaling. At 1080p with Low settings, the system achieves 80 FPS. Moving to 1440p Low drops this to 61.4 FPS, a reduction of 23.3%, and 4K Low further reduces it to 48.1 FPS, a 39.9% drop from the 1080p baseline. This scaling behavior indicates that the GTX 1660 Ti is the primary bottleneck as pixel count increases, because the CPU's performance headroom is not being fully utilized at higher resolutions.

At High settings, the scaling is even more pronounced. The 1080p High result of 43.5 FPS falls to 37.3 FPS at 1440p (a 14.3% drop) and then to 29.1 FPS at 4K (a 33.1% drop from 1080p). The close proximity of the 1440p High (37.3 FPS) and 1440p Ultra (37.3 FPS) results is notable, suggesting that at this resolution, the GPU is saturating its limits regardless of the preset, and the CPU is not the limiting factor. The 4K Ultra result of 25.6 FPS confirms that this combination cannot sustain high visual quality at 4K, as the GPU's 6 GB of GDDR6 memory and 288.0 GB/s bandwidth are insufficient for the game's demands at extreme settings.

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

At 1920x1080, the system delivers its best performance. Low settings produce an average of 80 FPS, Medium settings yield 61.4 FPS, High settings drop to 43.5 FPS, and Ultra settings bottom out at 45.3 FPS. Interestingly, the Ultra preset at 1080p performs slightly better than High, which may reflect variability in the benchmark scenario or specific rendering paths.

At 2560x1440, the results show a tighter spread. Low settings achieve 61.4 FPS, Medium settings produce 49 FPS, and both High and Ultra settings average 37.3 FPS. This clustering at the higher presets reinforces that the GPU reaches its performance ceiling around 37 FPS at 1440p when demanding settings are applied.

At 3840x2160, the framerates fall below playable thresholds for most settings. Low settings manage 48.1 FPS, Medium drops to 37.2 FPS, High yields 29.1 FPS, and Ultra produces 25.6 FPS. The data shows that 4K is only viable at Low settings, and even then, the margin above 30 FPS is slim.

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

The NVIDIA GeForce GTX 1660 Ti is built on the Turing architecture using a 12 nm process at TSMC. It has 6 GB of GDDR6 memory on a 192-bit bus, providing 288.0 GB/s of bandwidth. The GPU operates at a base clock of 1500 MHz and boosts to 1770 MHz, with memory running at 1500 MHz (12 Gbps effective). It contains 1536 shading units, 96 texture mapping units, and 48 render output units. The card's pixel rate is 84.96 GPixel/s, and its texture rate is 169.9 GTexel/s, with FP32 performance rated at 5.437 TFLOPS.

In synthetic benchmarks, the GTX 1660 Ti scores 12871 in PassMark G3D and 5226 in PassMark GPU Compute. Its percentile ranking of 55 indicates it outperforms 55% of all GPUs. The card's average benchmark score is 13925, which places it 0.4% ahead of the AMD Radeon RX 570X and 0.8% ahead of the NVIDIA RTX A2000 Mobile. The GPU's 6 GB VRAM is a critical constraint for Microsoft Flight Simulator, which streams high-resolution terrain textures. The data shows that at 4K Ultra, the system falls to 25.6 FPS, suggesting that both the GPU's compute throughput and its memory capacity are strained. The card's 120 W TDP and dual-slot design indicate it is a mid-range solution, and the measured results confirm that it is the limiting component in this pairing.

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

Based on the measured FPS data, the optimal experience depends on the target resolution. At 1920x1080, the Medium preset at 61.4 FPS offers the best balance of visual quality and smoothness. The Low preset at 80 FPS is exceptionally fluid, but Medium provides a significant visual upgrade while still maintaining a framerate well above 60 FPS. The High preset at 43.5 FPS is playable but noticeably less smooth, and Ultra at 45.3 FPS offers no advantage over High in this data.

At 2560x1440, the Low preset at 61.4 FPS is the only option that consistently exceeds 60 FPS. The Medium preset at 49 FPS is acceptable for those prioritizing visuals over absolute smoothness. Both High and Ultra at 37.3 FPS are below the 40 FPS threshold that many simmers consider the minimum for a responsive experience. For a more immersive experience at 1440p, Medium is the recommended choice, as it delivers 49 FPS without the visual compromises of Low.

At 3840x2160, the data clearly shows that 4K gaming is not practical with this hardware. The Low preset at 48.1 FPS is the only setting that approaches playability, but it sacrifices significant visual detail. The Medium preset at 37.2 FPS and High at 29.1 FPS are below 40 FPS, and Ultra at 25.6 FPS is unplayable by most standards. For 4K, the recommendation is to either use Low settings or reduce the resolution to 1440p or 1080p for a better experience. The data indicates that this system is best suited for 1080p Medium or 1440p Low, where it can deliver smooth framerates without overwhelming the GPU's 6 GB memory buffer.
