So I have an Acer laptop which supposedly has a powerful dual GPU setup in crossfire mode, with the integrated 6520G and dedicated 7670M. However, in every game I run the performance is such crap, like 15 FPS in low settings 800x600 resolution. This makes no sense as people run BF3 on 1366 res and ultra with 40+FPS with the same setup, and my friend who has the Intel 3000 HD + GTX 540M is able to run Chivalry Medieval Warfare on high settings 1366 and 40 FPS (while my Chivalry runs 15 FPS 800x600...Lowest settings possible), which theorecially is weaker than my setup... He just simply tweaked in his Nvidia control panel and got his laptop to use dedicated in order to fix low FPS. But since my cards are ATI, how do I do the same? That is make it so that the Laptop uses both GPUs like advertised, or at least use the 7670M over the stupid crappy integrated one?
Thanks in advance!
Edit: So I went into Devce Manager and disabled the 6520G to see what happens.. Now my entire desktop resolution is messed up. Its max res is 1024 by something and when I try torun chivalry it tells me "Your videocard does not support alpha blending with floating point render targets" and exits the game... It seems that my 7670M is not even working... Please help me thanks.
