Just updated recently to Win 10, I do also run a trial for SD's WindowBlinds and launched GCIII today the first time with those.
After the loading screen I got a message saying something about my gfx card drivers being too old, which in itself is strange, and never happned before under Win 7. However, even more confusing was that the msg said - if I understood it correctly - drivers should be at least from 2013, then ended with a line like "your driver is from 2015"?
Clicking this msg away worked, and the main game menu seemed fine.
Is there something specific I should do about this other than checking for a new driver (which right now NVIDIA answers with "try again later")
Does it play a role if I excluded GC from WindowBlinds skinning?
