Ok, A few weeks ago a friend was upset about Grid not working well with his X2, so I started trying renaming games executable to one from games that work with Crossfire setups. So in Grid, renaming to Oblivion.exe make CF works in this game, this was before 8.6. I did try other games. Nvidia Medusa Demo - Rename Medusa.exe to Crysis.exe enable CF. http://www.tommti-systems.de/start.html COD 4 if you rename to Crysis.exe you will get about 10fps more. TDU if use Oblivion will enable CF, almost double the performance. Lost Planet if you use COJ_DX10.exe will double the performance in some points. Devil May Cry - Rename to FEAR if you run under DX9. http://www.xtremesystems.org/forums/showpost.php?p=3081632&postcount=16 So if some of you want to try this, because, basically I´m doing this for every game that doesn´t work nice with CF and TWINMTB games. LP example. Settings COJ_DX10.exe Default exe. DMC4 1680x1050 all settings maxed with 8xAA. C2D@3,5GHz. L7R fron XS. DX9 - Default EXE. DX9 - Fear.exe.
