And if you used Windows "Update Driver" button, that's not a good sign either.
So i built my PC quite a while ago and decided to upgrade it just recently from a Geforce GTX 760 to a GTX 970. I have 8 gbs of ram and an Intel i5 4440 3.10GHz processor. I have all drivers installed and I should be able to play games fine as I smash most recommended specs, however I struggle to run the Witcher 3 above a 25 fps, and even worse I cannot play Borderlands the Pre Sequel without a chuggy frame rate. I just have no idea what to do about this anymore.
