It is for Nvidia only. The drivers are Nvidia based, but I think other drivers are ouyt there. I just got a Nvidia geforce FX 256 meg card and am not dissapointed. it has up to 8x anti-aliasing, as wells as 8x antioscopic filtering too. smokes w/o a hitch in Poser. If there is any doubt about if these glasses work, I was skeptical and got a set off Ebay for an amount I was willing to risk losing to be a waste. I tell you, I have NO IDEA why these aren't more popular. you all need to try them they take our renders to a whole new level, VR and 3d!
