I'm trying to increase refresh rates in VESA DOS games. I'm using the VBEHz TSR for this. It's supposed to work on any VBE 3.0 compatible card (I'm running a Voodoo5) and the author also claims that the tool works when run under Windows 98 as well, which is what I am using.

My problem is that it doesn't work when run under Windows, the games just play at 60 Hz as usual. It doesn't seem to matter whether I leave the DOS window open or not. The only way I can get it to work is by rebooting to DOS, running the tool, and running Windows again. That way it seems to stay in memory and I get 800x600@125 Hz as expected. But this solution is a bit cumbersome and I'd rather run it directly from Windows...
