I have a Vega 64 and I'm very exited about the concept and so far the performance. However I have had several issues with the drivers until the release of the latest version 19.1.2. Mostly I had issues with recommendations such as updating my drivers to the same version, installation failing to initiate, complete or in some cases removing the settings utility as far back as version 17.
What is my problem?
The drivers use of profiles. Before I actually took it upon myself to manually control the activation and manual configuration the drivers simply added a profile similar to the default Global profile but with a very weak fan profile resulting in temperatures nearing 70c during 15% - 35% GPU load. This struck me as odd and explained the unexpected silence.
My first action were to manually configure the individual profiles
This works alright until I leave a profile active while launching the associated process (exempli gratia Far Cry 5, Adobe Premiere) and aforementioned profile simply doesn't activate. I tried activating the profile post launching the associated process and that actually worked. Well, I could tell that the settings were applied from behavioral or rather by observing aesthetical differences. If I had to pick one "tell" frame-rate cap or chill function would suddenly activate.
Before I make an already boring read even more so, I will list issues in order of urgency:
If anyone have any experience with profile issues or know a good way to prohibit the driver settings component to limit it's freedom (like never adding or activating profiles without user input) that would be of great help.
Also, if you know the best way to utilize the full potential of my card with applications heavily dependent on OpenCL to do so, that's also valuable.
I bet there's a lot of great ideas and minds that have spent a lot of time on this and I am grateful of all help I can get!
There has been some issues with the profile settings not overriding the global settings with some cards and some drivers. The 'fix' was to enable 'histogram' in the profile and everything worked as expected. Don't know why..it just works. Since you seem to have histogram enabled..that rules that out as a cause.
The other possibility is third party graphics controllers..do you have Afterburner installed on your computer?
