Hey there Tom,
How's it going?
I've checked out the drivers and indeed, the soundcard one's haven't been updated since 2015 but just because Realtek did not release any new ones.
After fooling around with the settings i've managed to fix it!
What i've done was, right clicking on the ".exe" file, and ticked the option "Disable display scaling on high DPI settings" a
-> I've also Reestablished GPU default settings minus "FPS Objective" setting it to 60 FPS and activating Triple Open GL Buffering.
Since that, everything seems to work great!
Thanks for your assistance Tom. Do take care.
Best regards!
