Soma still not starting after driver update

[Kein]

It doesn't seem like your driver has been updated to the latest version. Pretty sure it should read 4.1.something.

I had uninstalled my drivers and installed the latest version for my card from the AMD website.

Install Catalyst 15.8 beta.

I've just tried that, once again uninstalling the old drivers and restarting the computer. Still getting the same problem.

Hey Helm, get AIDA Extreme BETA from here:

download, run and go to Display -> OpenGL.
Find OpenGL Compliancy and tell which versions are 100% supported?
