It seems it must have been the planet I was on and where I was at, both videos look similar in performance so I would say no there is no performance loss at least in destiny 2.
This driver causes multipanel display to lose connection for around 2 minutes after cold start up. From a normal clean boot up of less then 10 seconds to the login window, now I have to wait 2 minutes. Known issue - no fix yet.
Did you get a system info update notification in 3d Mark ?
I click install update but it hangs at system info installation at 72%, so fine let's uninstall 3d Mark and delete all the folders and try again. Still the same thing, it hangs at system info installation at 72%. So now I'm scratching my head a little bit and say let's try installing through Steam. That worked but now I get this.....
System Info is enabled
Have you updated the system info to 2.4.4180 and if you did, did you get this too ?
