Resolution Scaling

The measured FPS data for Microsoft Flight Simulator with the Intel Core i3-12100F and NVIDIA GeForce RTX 3080 Ti reveals a clear pattern of GPU-bound behavior at higher resolutions, with CPU limitations emerging at 1080p. At 4K Ultra, the combo produces 55.8 FPS, while dropping to 1080p Ultra increases that to 90.3 FPS — a 61.8% improvement. This scaling is substantial but not linear, indicating that the RTX 3080 Ti's rendering workload dominates as pixel count rises.

Moving from 1440p to 4K at High settings, the average FPS falls from 76.3 to 58.2, a reduction of 23.7%. The same resolution step at Low settings shows a larger absolute drop: from 129 FPS at 1440p to 97 FPS at 4K, a 24.8% decrease. This pattern suggests that even at Low settings, the GPU's fill-rate and memory bandwidth constraints become the primary limiter at 4K, rather than the CPU's 4 cores and 8 threads.

At 1080p Low, the combo reaches 165 FPS, which is the highest measured result in the entire dataset. However, when moving from 1080p Low to 1440p Low, the FPS drops from 165 to 129 — a 21.8% decline. This is a smaller percentage drop than the 1440p-to-4K transition at Low (from 129 to 97, a 24.8% decline), which implies that the scaling becomes steeper as resolution increases. The data shows that at 1080p, the i3-12100F's single-thread performance (Cinebench R23 single-core score of 1681) begins to cap the frame rate, preventing the RTX 3080 Ti from fully stretching its legs. At 4K, however, the GPU's 12 GB of GDDR6X memory and 912.4 GB/s bandwidth are the decisive factors.

GPU Role

The RTX 3080 Ti is the dominant component in this pairing for Microsoft Flight Simulator, particularly at 1440p and 4K. The GPU's 12 GB VRAM capacity is sufficient for the game's high-resolution textures, and its memory clock of 1188 MHz (19 Gbps effective) across a 384-bit bus yields a bandwidth of 912.4 GB/s. Benchmark results show the GPU scores 26,896 in Passmark G3D and 15,282 in Passmark GPU Compute, placing it in the 83rd percentile of all GPUs. Its nearest rival, the RTX 3090, scores 41,441 in average benchmark score — a delta of -0.5%, meaning the 3080 Ti is essentially within noise of the 3090 overall.

The GPU's boost clock of 1665 MHz and base clock of 1365 MHz are modest for a high-end card, but the 10,240 shading units and 80 RT cores provide the raw throughput needed for Flight Simulator's complex rendering. At 4K Ultra, the combo produces 55.8 FPS, which is just below the 60 FPS threshold many users target. At 4K High, the average rises to 58.2 FPS — still short of 60. The data indicates that the GPU's FP32 throughput of 34.10 TFLOPS is the bottleneck at 4K, as the CPU's 4 cores cannot fully saturate the GPU's capabilities at lower resolutions.

Notably, the GPU's Passmark DirectX 12 score of 110 is low compared to its DirectX 11 score of 223, which may reflect the game's API usage patterns. The RTX 3080 Ti supports DirectX 12 Ultimate (12_2), but Flight Simulator's engine may not fully leverage it. This explains why the FPS gap between High and Ultra settings is relatively small: at 4K, High yields 58.2 FPS while Ultra yields 55.8 FPS, a difference of only 4.1%.

How This Combo Ranks

The combination of the Intel Core i3-12100F and NVIDIA GeForce RTX 3080 Ti ranks 439th out of 1,795 tested combos in Microsoft Flight Simulator, placing it in the top 24.5% of all configurations. This is a strong result given the CPU's modest 4-core design, which ranks in the 72nd percentile of all CPUs. The GPU, however, ranks in the 83rd percentile, indicating that the pairing leverages a high-end GPU with a mid-range CPU.

Relative to the CPU's nearest rivals, the i3-12100F's average benchmark score of 13,516 is nearly identical to the AMD Ryzen Threadripper PRO 3975WX (13,534, delta -0.1%) and slightly above the Intel Core i7-1250U (13,462, delta +0.4%). This means the i3-12100F's overall compute performance is competitive with much more expensive processors, though its 4 cores and 8 threads limit multi-threaded workloads. In Flight Simulator, which is known for being single-thread-heavy, the i3-12100F's Cinebench R23 single-core score of 1681 is the key metric. That score positions it well for the game's engine, which explains why the combo ranks as high as it does despite the core count disadvantage.

The combo's 439th rank suggests that a majority of tested configurations achieve higher FPS, but many of those use higher-core-count CPUs. The data indicates that the RTX 3080 Ti is doing the heavy lifting, and users with this combo should expect performance that is competitive with systems using CPUs that score far higher in multi-threaded benchmarks.

Settings Recommendations

Based on the measured FPS rows, the optimal settings for this combo depend on the target resolution and frame rate. At 1080p, the Low preset delivers 165 FPS, which is far beyond the 60 FPS target and even exceeds 144 Hz refresh rates. The Medium preset at 1080p yields 127.7 FPS, while High gives 94.1 FPS and Ultra drops to 90.3 FPS. For 1080p users with high-refresh monitors, the High preset at 94.1 FPS is the best balance, as it stays above 90 FPS while providing significantly better visual quality than Low or Medium.

At 1440p, the Low preset produces 129 FPS, Medium delivers 104.8 FPS, and High yields 76.3 FPS — all above 60 FPS. The Ultra preset at 1440p produces 74.2 FPS, which is still playable but not as smooth. For 1440p, the High preset at 76.3 FPS is the recommended choice, as it offers a substantial visual upgrade over Medium (104.8 FPS) while maintaining a comfortable margin above 60 FPS.

At 4K, the situation changes. The Low preset yields 97 FPS, Medium gives 73 FPS, High produces 58.2 FPS, and Ultra drops to 55.8 FPS. Given that 58.2 FPS is below the 60 FPS threshold, the Medium preset at 73 FPS is the best option for 4K gaming. It provides a smooth experience while avoiding the visual sacrifices of Low. The Ultra preset at 55.8 FPS is not recommended unless visual fidelity is prioritized over frame rate consistency.

CPU Role

The Intel Core i3-12100F plays a supporting role in this combo, but its performance characteristics are crucial to understanding the measured FPS. The CPU has 4 cores and 8 threads, with a base clock of 3.30 GHz and a boost clock of 4.30 GHz. Its L3 cache is 12 MB shared, and it supports DDR4 and DDR5 memory in a dual-channel configuration. The CPU's TDP is 58 W, and it uses the Intel Socket 1700 with Alder Lake architecture on a 10 nm process node.

Benchmark data shows the i3-12100F scores 1,681 in Cinebench R23 single-core and 11,912 in multi-core. Its single-thread performance is the critical metric for Flight Simulator, which is known to be sensitive to single-core speed. The CPU's Passmark single-thread score of 3,444 and Geekbench single-core score of 2,224 confirm its strength in lightly-threaded workloads. However, its multi-threaded scores are modest: Passmark multi-thread is 14,015, and Geekbench multi-core is 7,413.

The CPU's nearest rival in average benchmark score is the AMD Ryzen Threadripper PRO 3975WX, which scores 13,534 (delta -0.1%), and the Intel Core i7-7700K, which scores 13,280 (delta +1.8%). This means the i3-12100F holds its own against much more expensive processors in aggregate benchmarks, but its 4-core design limits its ability to maintain frame rates at 1080p where the CPU becomes the bottleneck.

The evidence for CPU limitation at 1080p is clear: the FPS at 1080p Low (165) is nearly identical to what a more powerful CPU might achieve, but the scaling to 1440p (129 FPS) and 4K (97 FPS) shows that the GPU is increasingly the constraint. At 4K, the CPU's role diminishes, and the RTX 3080 Ti's 34.10 TFLOPS of FP32 compute dominates. The data suggests that users who upgrade the CPU to a higher-core-count part would see minimal gains at 4K, but could improve 1080p frame rates beyond the 165 FPS measured here.
