I used the /RES=1280x1024 from the FAQ to get my resolution right, but my refresh rate seems to stay 60hz, and I cant play any game at 60hz, with Worms3D you got a launcher in which you could set the resolution but im not getting something like that with Worms Forts, any way in which I can set my refresh to 85hz?

You could try out AT's launcher.

It should allow you to switch the refresh rate too.

I tried that one earlier, the launcher doenst seem to be able to set the refresh rate for Worms Forts :(
