I have following rig
intel corei3 540 3.04GHz
4 gb ram
XFX ati radeon 5550HD 1gb,128 bit
The question is that i have setted the texture quality at maximm,enabled light shafts,enabled bloom,normal shadow quality with AA OFF.After that i got texture popping and lagging then i disabled bloom and set shadow quality low.After that the game is countinously lagging.Right now i am playing skyrim with 2k texture with ENB (turned off ssao and dof with no aa) the game runs just fine but witcher 2 doesnt.So what will i do to fix this lagging and also if i upgrade my ram to 8gb will it work.
