ATI 用 win98/Me 有救了,從 rage3d 看貼來的改法.

Fix for the 60hz refresh bug for W9x & Cat 3.1

Start regedit, go to HKLM/Software/ATI Technologies/Driver/0001/DAL (or instead of 0001 whatever number your current driver uses).
Insert a new binary value, named "DALRULE_ALLOWNONDDCCRTALLMODESUPTO1600x1200". Set the value to 01 00 00 00.
Or, you could try "DALRULE_CRTSUPPORTSALLMODES" and set this to 01 00 00 00 instead. (Both work here perfectly, the difference being that one allows resolutions up to 1600x1200x200, the other 2048x1536x200.
That's it, just reboot.

IMPORTANT: you need to set the refresh rate for all resolutions you want to use manually with regedit, since the driver will likely set them to 200hz when you switch resolutions, so you won't get a picture unless your monitor can handle that. So, go to [HKLM\System\CurrentControlSet\Services\Class\Display\0000 (or whatever number your monitor has)\MODES\x\y,z]. Make a new string "RefreshRate" and set it to "85" or whatever you like and your monitor can handle.
If you forget to do this you might be forced to boot in safe mode since you might get an "out of range" value by your monitor upon boot-up...
