I almost choked on my pizza as i saw what happened in game.
My characters Look like something out of Minecraft.
also....
DisplayModeWinLeft "1148"
DisplayModeWinTop "210"
DisplayModeWinWidth "816"
DisplayModeWinHeight "638"
This is set by where you leave yoru D3
you will notice that if you try to resize the game or move it.
everything resets in the d3 prefs pretty much.
my suggestion is to make D3 small and move it to the bottom right corner of your screen.
If it is not visible on the screen. your graphics card/chip doesn't have to load the graphics.
also by changing the D3 prefs, you can change everything else to a smaller size, and reduce Quality ect.
this allows you to reduce usage on the cpu. because then the cpu doesn't have to load all that stuff.
also turning off things like the games General chat and trade chat. and turning of display bars/numbers also helps the cpu.
