Issues with refresh rate on a CRT (CRU)

hi! ive started using windows again and the best way i found to made custom resolutions and refresh rates was with CRU, the thing is that Quake Live doesnt seem to care about those, instead it picks the default EDID closest to whatever resolution, not refresh rate. For instance if my desktop res is 640x480 160hz quake live will use that res but at 85hz, and i have to open CRU, disable all established resolutions, run restart.exe and open quake live again for it to work. Any suggestions? this is super annoying and only happens with QL, not other games
