I updated to this today and I’m still in the 60 to 70fps range so i don’t really see any difference at all, you could have a corrupted driver when it installed i guess but other than that i don’t see it being a problem for the actual version since everyone would get it.
I use the “AMD HD 6870”
(just thought I’d say so you know it could be another problem even if it was just caused by the install itself or another problem you wasn’t aware of.)
