I am using adobe premier pro 2023, Windows 11(latest)
I have Sapphire amd rx 6700 (Non-XT). I can't use this gpu for hardware encoding. I checked supported gpu's from here; https://helpx.adobe.com/premiere-pro/system-requirements.html#gpu-acceleration
as you can see, older versions of this gpu is supported. In my opinion Amd 6700(non-xt) released after Amd 6700-XT so adobe premier pro must be update about this.
