ATI Catalyst Driver Release 8.12 Hotfix HD4850X2 Test
 

ATI has recently released a hotfix to their Catalyst Driver version 8.12 intended to improve DirectX10 performance in multi-core CPU systems and to resolve BSOD issues using dual ATI Radeon HD 4850 in CrossFireX configurations. With a HD4850x2 in hand, I had to see if the 10-25% performance increase in some applications was indeed possible.
