Hi,
I get some pretty weird behavior with my new gaming rid. This machine is build to run Battlefield 4 at above 70FPS and it usually does; however sometimes I get these massive drops in FPS. Sometimes games (BF4, Metro LL, Thief) run at 30FPS sometimes as low as 10FPS. Not sure what this sudden drop triggers.
To save some time, my specs are
Usually what helps is a reboot. So far I have noticed that the FPS is determined right after I reboot. I can expect low FPS when I open FireFox and even JavaScript driven elements that move (menus and stuff) render rather slow on a website. I reboot again and usually both web content and games run very smoothly. Important is that everything runs slow or fast at the same reboot.
I am not even sure whether its something to do with CPU or GPU. I dont run any unusual software then ever before. One is never safe from viruses but this has been happening pretty much ever since my first game launch a month ago.
At first I was blaming PhysX because I didnt know whether to install it on my AMD card or not, then I decided to remove it but this problem occasionally reappeared. My missed guess was PhysX because some forums would suggest to install PhysX even on AMD cards to play Metro LL and some passages that obviously used PhysX ran very poorly compared to other passages in the game. Now my PC is PhysX free and about 50/50 game attemps run smoothly / laggy.
Another slight hint is that games would more often run smoothly if I run them as soon as I reboot. If I was to run a game 30 minutes into being booted to my system chances are I am gonna have to reboot.
Any idea what it could be?
