I am trying to play crossfire on my 2009 lap - Sony Vaio with 4 GB RAM(2.89 usable) , and a fucking graphics card - Intel HD Graphics 1000... I can't make all of the 4 GB of RAM usable, cause of the low Graphics card..Anyway I play on low graphics, Windows is fully set to max performance, but I dont use gamebooster cause it makes the game lagg more and idk why ... Usually I get like 50 - 60 fps, and mouse sometimes stucks... So what can I do to improve my fps? It is even possible ?
