tacticalnuggets 24 Posted December 5, 2010 I have upgraded to a 5870 from a 4890. There seems to be an issue where arma2 will not use above 66% activity from my GPU. I'm not sure why, as my 4890 went to 99-100%. To confirm this is simply an issue with arma 2, I tested with SiSoftware sandra and easily pushed my GPU to 100% activity. Catalyst will take a snapshot of the activity before you just windowed out or ended an application if its still open. (I did this several times to capture the max) It averaged at 50% activity and maxed at 66%. My card does not have this problem after running a SiSoftware sandra test. This leads me to believe its a problem with arma 2, possibly the bad 1.55 patch. Does anybody else have this problem? I first noticed that I needed to run these tests when my frame rate was actually worse than my 4890 when I first started. I had to bump up my core clock to be on par with the frames it had before. That should not have to happen with a card that is clearly more powerful than the 4890 based on all the other benchmarks out there. Share this post Link to post Share on other sites
EDcase 87 Posted December 5, 2010 Something wrong with settings. I went from GTX285 to HD5870 and difference was amazing. I think your problem is Vsync is not possible to turn off with crap ATI driver. Get the latest ARMA patch 1.56 which as Vsync option in graphics settings. I think you will be happy with the difference... Share this post Link to post Share on other sites
stun 5 Posted December 5, 2010 I use a 5870 with vsync on and and when playing missions on Cherna my card often pushes to 100% Playing on Takistan it doesn't seem to go to 100%. I guess the card only uses what it needs to render the scene. Share this post Link to post Share on other sites
