first of all before you tell me to install the windows comparability toolkit i already have. it did remove the annoying mouse lag but other than that it still lags a lot. but unusually only when there is text appearing on the screen (if i stand near writing on the wall or random texts of guards, serviles or other people saying things).
my computer is new with really good specs. which i'm sure is the incompatibility.
specs
CPU: i7 4770k
RAM: 24 GB Crucial Ballistix Elite
GPU: EVGA Geforce gtx680 4 GB version
those are the big ones but if i'm missing a crucial part in this investigation ask and ye shall receive.
