Rainbow Six is finally here, and I'm testing it as we speak.
Okay, so it's missing the soundtrack and there's graphics issues where everything's not drawn, no matter what resolution you set it to.
If you set it to Force Software, it'll work but the graphics are bad and the game slows down noticeably even at 640x480 resolution

just checking but have you sent GoG Support a note with your sysem details (Dxdiag) info about this - it might be something they can fix or it could be something to do with you graphics card - sadly as graphics cards advance they tend to drop at lot of support for older visual rendering methods - which is why older games can look worse on newer hardware

I sent just about everything and a screenshot, and sent an e-mail to follow up, but no one's answered.
