Let me say hallo to everybody 😀

I'm curious to know if anybody of you managed to change refresh rate for DOS legacy games running under WinXP operational system, except of modifying graphic card BIOS (using RadEdit tool).
I have ATI RADEON based graphic card (particulary ATI RADEON 9800 Pro) and playing e.g. Redneck Rampage (in combination VDMSound + NOLFB) hurts my poor vision in 60Hz refresh rate mode.

I read through many web pages to find out any information even solution but as it seems so far it's irresolvable problem. Many utilities such a UniVBE, VBEHz etc. work on basis of support for VESA 3.0 compatible mode and ATI supports only VESA 2.0 one 🙁

Please help me if you know any functional software solution how to make ATI work above 60Hz mode 😀

My hardware details: P4 2,26GHz, Intel D845GBV motherboard, 512MB RAM, ATI Radeon 9800Pro, SoundBlaster Live! 5.1, WinXP SP1)

I'd like to know if there's a decent fix for this, however some games might use the 60hz as a timer and might run too fast if ran at a higher refresh rate?

However DOS games run through DOSBox run at whatever screen refresh rate you have in Windows (which is nice!), but this isn't "official" DOS.

What I do on my PC is override refresh rate changes (this is set in the Monitor tab on my ATI Catalyst drivers). This makes all Windows (well nearly all...!) run at the same refresh rate as the desktop. What I've noticed is that DOS games often now run at 70hz, which is better than 60hz but not much!
