Dont ask me about VR mods, you can use your own common sense from these pictures. Dont attempt mods if you're a lousy modder.

Try it in Vantage...seems way better than a 580 there.

Guess that counts me out :(

for you guarnar for sure i'd encourage, if you dare take up my dare :D

just really unfriendly, the clocktool sets clocks randomly, sometimes at 2d volts and all , why must Ati always have these weird soft bugs, hardware does seem sound
