Me to, runs really well on my 7990 with the new beta drivers and it dose not sound like it's stressing the card either. My 7990 sound loads louder when playing evolve.
I have a question about soft shadows in the graphics settings, which setting should be better? soft or the AMD option? I noticed the AMD option used about 12mb less vram, but I'm not short of vram.
Yeh I think it is really cpu intensive so you probably are not getting 100 usage on on your 7990. I haven't been getting 100% usage on a single 980!
Still runs great though but its clear you need a powerful cpu for this game.
