I updated to the latest 16.6.1 Hotfix driver and had several Event ID 16388 ATI EEU Client Events at boot. It also took a few more seconds for the login screen to appear and Photoshop decided to disable use of the GPU. I note the last Hotfix is not WHQL certified.

I've gone back to the previous WHQL driver version 16.1 I was using and now have no problems.

What's the latest WHQL AMD driver and where do you find the previous WHQL driver versions? What's the best latest "bug free" driver to use.
