A simple, but easily overlooked possibility: make sure the drivers for your video card are up-to-date.
Thanks for your comment!
Sadly I already updated my drivers to the latest version and it still doesn't work.
Did you ever figure out a solution? I have the same issue.
The game worked for me in windows 8.1 and I finally gave in and installed Windows 10 and everything else works just fine except this game. Like Witmoos the game loads, shows the cinematics, main title screen and then loads the game to just the HUD. Everything else is black and there is ambient sound/music but no gameplay even when I hit buttons to try something.
I've tried reinstalling the game, checking to see my drivers are up to date, turning off SLI both in the game settings and disabling it, nothing seems to fix it.
It's a shame because I really wanted to go back to this and play it once I finish Blood and Wine.
Anyone with any suggestions or solutions please let me know. Thanks...
