Every single time I play online after about an hour of play my FPS plummets. It happens every single time until I restart the game client. I usually play Sa-Matra wasteland and I can play first the first hour at a high fps. Usually 60+. Then it hits about the hour mark and the game starts to stutter a bit then fps drops to 15 and gets worse if I turn or move. I have no idea what is causing it. I run the game off an SSD also.
Specs are as follows:
I5 3570k @ 4.8ghz
32Gb Ram
GTX 680 sli
Windows 8 64bit.
