Catalyst 9.12 is out for Windows and Linux. Seems to me it made a bit of improvement on Hagrid (my overweight laptop), so if you have not upgraded in a while now may be a good time to do it.
Note: If you have a laptop with an ATI Mobility Radeon card, you won't be able to download a workable driver from ATI due to restrictions imposed on them from the hardware vendors. They really wants to redistribute new versions of the drivers themselves. Which sorrily means you will have to wait for a long time for an upgrade (if you ever gets it). Enter Mobility Modder.net. This software will modify a downloaded ATI driver for the desktop GCs, allowing you to install them on your laptop! I have used it successfully on Hagrids 3650 card; highly recommended!
