AMD/Adrenalin driver update

Have tested the last couple of driver updates from AMD on my system (with a simple RX 6600 and 20.0).
25.3.1 - seems stable and works OK, my current recommendation
25.5.1 - problems with AI functions, subtitle generation did not work (symptom: no subtitle track was generated) - AVOID
25.6.1 - serious performance issues on edit/color pages, even at 1/4 playback resolution serious jitter - AVOID

In all cases, default installation with all special gaming functions turned off

And just to confirm: You do NOT have RivaTuner installed on the system?

No RivaTuner, don't even know what it is

If you don't know what it is, then I'm not sure you're sure it's not on your system and running.

Open the Windows System Information app, and in the Find what: area at the bottom, enter rivatuner and make sure it's not on your system. Please let us know what you find.
