AMD Driver Timeout when attempting to bake high to low poly models

Use AMD Driver 26.6.1 on a 9070XT
Have GPU raytracing enabled
Create new project with a low poly mesh
Head to the Bake Section and select the high poly mesh
Set output size to 4096 or higher (though even 1024 seems affected)
Hit Bake Selected Textures
Then the application will go through each map without baking anything, proceeding to an AMD popup stating Driver Timeout.

I have uninstalled and reinstalled Painter, removing preferences. Changed Registrys as recommended to 60 seconds, as well as tried tuning my GPU to have the lowest Max Frequency it can. All these don’t fix the issue.
The only thing that fixes it is disabling GPU Raytracing, which defeats the point considering Painter V11.1 added Vulkan which should allow AMD cards to use raytracing to speed up baking. Without it something that would take 5 minutes takes roughly an hour for 7 mesh maps.

    After discussion with our QA, this is something we’re aware of and are on discussion with AMD on the subject. Unfortunately, we frequently face issues when baking with 9070XT and the driver doesn’t share with us the info to bypass the issue. Resulting with this Driver Timeout popup.

     

    You can try to increase the TDR value to avoid the popup, but I can’t assure you this wills solve the problem. You can also lighten your High Poly mesh a little bit. A decimation can help.

    I should also add, I’m on the latest version of Painter as well. I recently switched to AMD from NVIDIA but I have no remnants of NVIDIA drivers present. I’m also using a 9800x3D and 32gb DDR5 ram
