J_Darnley: Wow. I completely forgot that I made this thread.
It must have been a bug on GOG's website as this contradiction has been remedied and it is now back to Vista and later.
Thanks anyway.
The DC version afaik is port from PS3/4 (forgot which) and was never ported to openGL (DirectX 11 only so no Mac or Linux version of DC unlike the original).
IF the windows version of the original has option to use opengl renderer, like the Mac and Linux ports do, it
MIGHT work but XP was never officially supported. Actually, with DC the official support starts from Windows 7 SP1 so even Vista support was dropped and it also seem to require 64-bit operating system unlike the original.
