How much VRAM do I need for this sim?

Most folks running at 1080P all the way to UHD won’t chew up more than 8-9 GB of VRAM, and I’m on DX12 because I have a 16GB Intel Arc 770. (Guru3D VRAM Utilization)

These scenes below are 6.3GB used. I’m running a mix of High / Ultra at 1080, 100 TLoD/OLoD, Live Traffic, Live WX and FSLTL models. About 45 fps in-cockpit.

On approach, landing, rollout and taxi, I’m running about 7.5GB used and around 30 fps.
