Hey, i just installed a new video card and it seems that SC2 wont run well at all. It will run at 60 fps and then when i get like 100+ units on the screen it will drop to 0-1 fps. This is with every option set to low, i feel i should be able to run Ultra at a decent FPS. I've recently updated drivers, defragged, and everything else i could think of to try and fix it with no avail. Any help would be greatly appreciated! I cant seem to post my DxDiag, its too long to post, the file is too large to attach, and when i compressed it to a rar. it wont let me upload the file i get the error message "Invalid file".
