So I am doing a project and I am using UEIV, and when I go under sculpt tool and then click create the screen flashes. Then on top of that when I click play I seem to be receiving extreme FPS drop. Then I get massive FPS drop when trying to edit terrain. I make a plain 200x 200y 1z. And then things get worse. It tells me I have to rebuild lightening after that nothing happens! I have no idea why this is happening I am running it on a i7 4820k and a GTX 780. Is UEIV AMD optimized only?
One more quick question how do I get trees?
