Thats the setup I'm currently running.
Never lagged/screen lagged before. Since I recently got back into D3, I can solo fine but as soon as more than 1 person joins or start doing higher GR, my screen lags out really bad... to the point I cant even do normal T10 rifts to farm GR tokens...
Tried many different things, contacted blizzard support as well and nothing has changed.
everything is up to date and D3 has been Uninstalled and Reinstalled...
I'm on my last legs here trying to fix this.
also, doesnt matter what the settings are on will still do the same, and I have a cooling fan underneath my laptop as well
