GTA 4 Crossfire help

[EchoOne]

Hello,I just got another 6870 (XFX 2GB) and i put in crossfire with my other 6870 and every time i try playing gta 4 with cf on i get TERRIBLE performance like 20 fps as when i use just the 2gb card i get 40+ fps all maxed out...Is there anything i can do the fix this issue...Or do i just have to play with 1 6870...My crossfire works well in other games

Bf3,Metro,Amnesia,Tf2,Garrysmod,Dirt3,Killing floor and badcompany 2...But gta 4 just hates me...

You should try making a Ap. Profile for your GTAIV with the crossfire compatibility of Mass Effect 3, I had 15% more FPS after doing this.
