At 8GB VRAM it is very limited for Unreal Engine. We need AMD and Intel to start competitive cards or we will have a decade of stagnation.
The values as said in last paragraph are a bit meaningless, a 3060 115w does 9200 points so the "20%" is too early to state.
So it's basically a 2080 super, but just costs more than a 2080 super?
