I have an AMD 5850 with all stock settings, FurMark tests showed min27 fps max 30 at full load for the full 15 mins. I have catalyst control centre set to maximum performance not quality. I've tested my CPU for faults which was fine, my PSU is 1000w corsair. When I use amd overdrive to overclock my card it causes my wireless card to disconnect every 5 minutes. I can't seem to figure out why my FPS is so low in game and why the wireless card drops after overclock. Im trying to play APB reloaded in no way a demanding game and one i have played fine in the past. I have done a full system restore and defrag also have catalyst control centre V13.8 installed.
