I used to be able to run league of legends at 60fps + at medium settings, but recently, I'm barely able to reach 35 at the lowest settings. Youtube videos are also occasionally choppy. My video card driver has crashed once and restarted itself once a few weeks ago, but I'm not sure if it's related.
here are my specs http://speccy.piriform.com/results/ZCChKMxqmIGRCbpOJfoGJgi
help would be appreciated
