This is the first time i use CF.
Core i5-3570k @ 3.4
DUAL Ati 7950 3GB
16 GB Gskill Ram
I just got another ati 7950 to (total of 2 right now). I put in the new card, put on both Crossfire Bridge ( each card has 2 CF, i got 1 CF connector from each card, so i figure i will just both of them on). Go to CCC and enable Crossfire. When i run game like Tera, i see that only the main GPU has the usage at 50%, and 2nd GPU does not run at all. Then i run Furmark GPU Stress Test, it shows that only the main GPU has the usage at 99%, while the 2nd GPU's usage only at 0%-5%. Why it that? Then i play Crysis 3 Beta, Yesterday i plays C3 with only 1 card at highgest setting and get aroun 23-35 FPS, today with CF i get around 30-40, this time while playing C3, the second card did run, but i thought the CF performance should be close to double the performance of 1 card. Can someone explain for me pls ?
