how do you mean it lags was it loaded up as a clean install are you using 3rd party crapware as 9/10 its not the driver its the way the user has loaded it. Sick of the driver abusing the great thing is these drivers have improved since 18.2.1 I was skeptical but since loading up a fresh batch been quite happy with them. Tho I dont load up any form of crapware I load up the basics as intended. Once you start loading up crapware is where the issues arise.
