MS Flight Simulator 2024 can consume...who knows how much.
I know my 10 GB 3080 ran out of VRAM playing it on Ultra, and i was getting as low as 2 fps because I'm bottlenecked by the PCI-Express bus as it has to constantly page the entire working set of textures and models in and out.
I'm getting a 5090 for that, plus I want to play around with 7B parameter LLMs and don't want to quantize below 8 bits if I can help it.
