RX480 Performance Issues

[gent23mj]

I decided I wanted to try and sell my Sapphire Nitro RX480 4GB and so I wanted to get some Heaven benchmarks to help sell.  I know its an old benchmark, but its an older card so why not?  The results were not what I had gotten in the past nor what I am seeing others get.  I seem to be about 20fps lower, in general, from those running similar clock speeds.  Any idea what might be causing this?  Here is all the info I can think to give.   I will also supply my benchmark results using different AA settings below. GPU Temps stayed in the hi 60s since I have my fan curve adjusted a slight bit.  I use DX12 in The Division but otherwise I don't.  I don't know if DX11/12 is an issue with Heaven or not.  Thoughts?  Ideas? Help?

17.1.1 is a hella old driver. 

 

Try a clean install of the drivers and possibly a Windows reset.

Drivers and driver packages have always confused me.  Whats the best way to start clean?  uninstall all drivers and download the radeon relive and let it do all the work?
