Thank you. I'm just hoping it will run on majority of computers. I have a 980 ti and I don't have any performance dips just yet.
I have the same card so I know how hard it can be to make sure the map is running optimal because it can handle pretty much anything, but there is a way to check the performance of a scene in numbers.
While ingame open the console and enter "r_showprimitives 1" then check what the "draws" and "shdw" count is, to turn it off just change the 1 at the end to a 0, plus you'll need to walk to an area and then open the console as I don't know how to get it running permanently.
As a general rule of thumb I try to keep my draws around the 2000 mark (with a max of about 4000-5000) and try to keep the shadows at the 80,000 mark (with a maximum of about 100,000). That at least helps to diagnose the performance of a scene a bit until beta testing starts of course.
