Kodi can activate Video Super Resolution for Intel gpu in v21 Omega prereleases.
Testing and feedback with discrete ARC gpu is requested for fine-tuning before official v21 release.
The team tested with Intel integrated gpu. There wasn't much change in picture quality for progressive material, and the results for interlaced video were inconclusive (some good, some bad with low quality deinterlacing artifacts)
* Turning on VSR
- Kodi v21 alpha 3 (portable install or backup your Kodi data first just in case)
- Request VSR in Kodi: Settings > Player > Allow use DXVA Video Super Resolution: ON
- DXVA render method + DXVA scaler must be used (dxva decoding is not mandatory)
Kodi can only request for VSR to be used, the driver ultimately decides based on a number of conditions and provides no feedback.
Known conditions for VSR:
- SDR only, no HDR
- video <= 1080p
- display resolution > stream resolution
* How to check that Kodi requested VSR?
during playback press alt-o for video debug info and check for the text " Video Super Resolution: requested" in the Render Method line.
(see https://kodi.wiki/view/Player_process_info / Video Debug Info paragraph)
* How to check that VSR is actually active?
Monitor GPU activity in Windows Task Manager > Performance > GPU, there is much larger usage increase when playback starts with VSR engaged (near the max on igpu). Maybe the gpu fan will start spinning.
* What to test
Please test progressive and interlaced sources.
It's possible that the stronger ARC gpu will have more picture improvement than the entry-level ones, so please state the model in your reply.
Check for deinterlacing artifacts (combing, low quality blend of fields, flickering,...).
Intel provides high quality deinterlacing without VSR and it should be the same with VSR or we'll have to think about excluding that case.
