I have a GeForce 2 ti card and have so far had difficulties with three Vesa games, namely Ark of Time, D and Chronomaster. All of them works with the beta version of Display Doctor 7, that was once availible as a free trial download but has now vanished and will not be sold.
I would advice anyone with a Geforce card against using any of the free Display Doctor versions, such as 6.53, since it does NOT support the Geforce-series. I learned the hard way. It messed my system up completely.
Now if I could only get around that "your 21-day trial period has expired" with the version 7 I wouldn't have to worry about VESA compatibility again. Let's hope SciTech decides to put the beta version out for free download as well. It really works very well.
