Wow i feel stupid i totally forgot that i was playing around with catalyst control center in windows and changed the amount of built-in memory to 32...
Anyway now with tormod,xorg-edgers,radeon-rewrite ppa things are working more smoothly, etracer and most texture issues are gone
but still one issue that i have is that blender still has artifacts,mainly with the menu and also yo frankie doesnt work , but i still need to check rest of my games
(sorry for the way my post looks as i am posting on my phone)
