Hey everyone, I need a little help with something today. So I got a new card about 20 days ago, specifically a Powercolor 7850, and it is a GIANT improvement from my last card that was a AMD Radeon 6450 which was really slow. Pretty much all of my games I can play at the highest settings and get a good framerate. But I went on DayZ today and tried to play some, I had everything at very high settings and I got like 15 fps. So I was like alright, I'll just lower the settings some. Eventually I set everything to very low and I still had about 15 fps. Does that make any sense that I have the same fps on each setting now? Because ever since about July when I bought the game my 6450 played Dayz great, I got up to 40 fps sometimes on low settings and like 3 on Ultra. Now I get about 12 on low settings and 12 on Ultra with this card. What's the problem.? Because it doesn't make much sense to me. Also games like PlanetSide 2 and GTA IV do about the same thing. I can play on any setting and I still keep the same fps, although I get a decent framerate on those I won't complain to much, but still. But other games like APB Reloaded and Gotham City Imposters I got about 19-25 fps on my last card on low settings. Now I get about 60 fps on APB maxed out and over 100 fps on Gotham City Imposters. I really have no idea what to do right now because right now my last card played DayZ better than this one at low settings, and idfk what's going on with all of this. Any help will be greatly appreciated and I need to find out if I can fix this sometime soon, because one of my friends just bought ARMA today and wanted me to play some. One more thing, I just went on singleplayer on ARMA 2 and I get about 30 fps maxed out and around 50 on very low, so yeah.. Btw here are my specs: My Specs: AMD Athlon II X2 260 3.2 ghz PowerColor Radeon 7850 CORSAIR Enthusiast Series TX650 V2 650W 4 gb Ram Windows 7 Home Premium 64 bit OS 465 gb Hard Drive

Alright, I'll give it a try.
