Lag

[AceTheGunNerd]

I've been playing PR for a little, but for the last few months it's been unreasonably laggy. When I first started playing PR, it was relatively smooth at my native resolution, but now I have to put all graphics settings to low and lower my resolution and even then I don't really get the smooth gameplay that I had before. This kinda made me discouraged and I didn't want to play for a while anymore.

Has this happened to you guys? How do I fix this?? Any tips?
