This has been happening for a few patches. Everything will be very choppy and then move smoothly for a minute or two. I can still play with the choppiness but it is very irritating. The game used to run smoothly with some of the settings on high. They are all low now and I can't fix it. I have tried many many things! I'm running it on a laptop which isn't really the best for gaming but I used to not have this issue at all. A little help would be greatly appreciated :)
