I just installed Steam but open source driver is a bit dodge playing Fez (VVVVVV does not, unsuprisingly tax GPU.) Anyone have experience with DKMS & propriety FLGRX driver? Could you explain how to install & configure?
I don’t have any experience with the fglrx driver or steam, but I would suggest you install the driver via the RPMs:
https://en.opensuse.org/SDB:AMD_fglrx
In that case, you should have no need to setup/install dkms.
The fglrx driver should be used automatically after you install it, normally there’s no need to configure anything.
I’ve found http://www.sebastian-siebert.de/ site to be useful (i use google translate as mein Deutsh ist schlecht).
I’ve never had a problem installing from the makerpm script.
