pawel187 0 Posted October 20, 2012 (edited) At first sorry for my english if I'll make mistakes or sth... Man I bought second 7870 for dayz and arma and I was very disapointed with performance of crossfire. My spec is i5 2500k oc 4.8, 8 gigs ram 1333 and radeon. I was able to play dayz on single card (GPU ussage shown on msi afterburner - 99%) with about 30fps with little stuttering (all details very high, only AA normal). Crossfire 7870 got me about 30-35fps and lot of stuttering (GPU ussage on both cards about 30-60%) It was lot worse than single card. I was trying lot of things (diffrenet drivers, etc), Than I decided to check if my HDD didnt bottlenecked rest of my spec... and then I discovered ramdisk... man that was IT... I limited my fps at 60 with afterburner, turn vsync on and now I play Dayz with constant 60 fps without stutters (80-99 GPU Ussage on both 7870) , even with fast rotating camera, no stutter or fps drops at all. Small stutter and fps drop occur only from time to time when game load something that I had to left on my HDD. I made 3 gigs disk ram and copy most importenet pbos from Addon folder and @DayZ (On monday I'll get 32g of ram, make 20g diskram and install all game on It :)). You can find some easy tutorials how make arma run from ram disk... about Arma Benchmark... I'm not sure what files I should copy for benchmark so I've run It with same files that I use for Dayz and few from common folder... All details Very high, AA Normal Distance 2400... Crossfire HDD - 46fps ... Crossfire Diskram - 75fps :)Since U use SSD I'm not sure Is that Case of Your problem tho Edited October 20, 2012 by pawel187 Share this post Link to post Share on other sites
