I recently bought a Rx 7600 XT, I upgraded from a gtx 1660 super. I used DDU to remove the nvidia drivers before installing the new graphics card and installed the latest drivers for the 7600xt. When I tested my game performance, it was performing at about the same level or worse than the 1660super. I already tried to update my bios, reinstall windows, remove and reinstall AMD drivers, using two non daisy chained power connectors, disabling SAM and ReBar (Which increased performance slightly).
My Specs:
rx 7600 xt
ryzen 5 5500
1x 16gb DDR4 3600Mhz
Raidmax thunder RX-735AP PSU
