Graphics now software only after attempted use of integrated gfx

[Nicholas Lear]

Update:

Totally uninstalled my AMD driver according to this guide https://community.amd.com/thread/180667

Uninstalled Premiere and re-installed 12.1.0 with restarts in between.

Trashed prefs.

But Open CL is still not showing (in Premiere or Media Encoder)

Have now completely uninstalled Premiere, Media Encoder and Creative Cloud. No success.

I saw this thread with the same looking problem https://forums.adobe.com/thread/2466011 so it would seem it is the intel driver and nothing to do with the small update from 12.1.0 to 12.1.1

But that driver is uninstalled now – I no longer have the pink problem, just that Premiere no longer gives me OpenCL accelleration which it did before.

GPUsniffer confirms it isn’t seeing my RX 480 which it was before.

Panic over, have solved problem.

I re-enabled the iGPU in BIOS and then downloaded and installed the previous Intel graphics driver for the HD 630 – v15.60 (Support for Intel® HD Graphics 630 )

Interestingly, during install it stated that I had a more recent driver installed – even though I had un-installed the driver via Windows. I ignored that error and went ahead.

Now I have OpenCL back AND hardware accelerated H.264 encode – win win!

All of this would have been avoided if I hadn’t installed the latest Intel graphics driver. Happily that other thread pointed me in the right direction.

I did a quick test of H.264 hardware acceleration vs software of a 2min 4k timeline with minimal fx output to 720p which is what I usually do at the moment to send offline edits to my client. When I did it direct from Premiere, software won at 2.50 vs HW at 3.04. But from Media Encoder, hardware won at 2.39 vs 2.59 for software. Slightly odd, but at least it does speed things up a bit in AME & I imagine those savings really add up on a big timeline with lots of effects.
