In the case of flight simulators like MSFS the main bottleneck is often the CPU. This is due to the nature of the game, which relies on advanced physics algorithms, atmospheric simulations which require significant CPU processing power. In MSFS, rendering the scenery and flight simulation calculations also put a heavy load on the CPU.
A graphics card like the RTX 4090 is very powerful and at resolutions like 2K or 4K, it won’t be the limiting factor. Higher resolutions, such as 8K, could lead to situations where both the CPU and GPU are heavily stressed. At 8K, the GPU has to process a much larger number of pixels, which could impact performance, especially when paired with the demanding simulation engine.
So, at 2K and 4K resolutions, the CPU is more likely to be the bottleneck in and the RTX 4090 will handle the GPU load with ease.
At 8K resolution, both the CPU and GPU could become performance bottlenecks.
