I had some major issues with my pc for about 5days and yes.. fps dropped to like 20-30. Was sooo gay....
I could not get it fixed ... so all I thought I could do is backup and re-install everything.. fresh win7 install
Thought it couldn't be my specs because I've played like this for ages.. HD with all maxed out settings
win7 64bit
6gb ram
gtx260
And as the same that happened with you reaper... Just randomly started.. idk wtf happened but yes... That was what I did.. Prob not the best solution but I needed a fresh install
