Vallerii Zapodovnikov (ValZapod) added a comment to T81307: *.mp4 video file colors are different?.

You need to understand that the default is indeed because of resolution. For HD video it is BT.709 and for sd video, it is much more complex. And do not let me start on UHD HDR, it is multiple versions of BT.2020 & PQ (in YCBCR or BT.2100 ICTCP) and variant of it IPTPQc2 in Dolby Vision profile 5. So it is crazy.

ffmpeg does not support "playing" with file without correct metadata. For HD video, you need to set ffmpeg incorrect_color_h264.mp4 -c copy -colorspace bt709 -color_primaries bt709 -color_trc bt709 out.mp4.

You can turn off G-sync for only Blender in 3D profiles in Nvidia Control Panel. But, I think you should try LG C9 or other display with very good G-sync.

Vallerii Zapodovnikov (ValZapod) added a comment to T70011: NVIDIA issue prevents full indirect draw call batching performance.

@Brecht Van Lommel (brecht) @Clément Foucault (fclem) Hey, that is not a good idea. At least maybe test it? What version of driver fixed that, you know. Also maybe try to check what connected issues were indeed because of those indirect calls. Maybe some of them used them wrong, then it is a problem, etc, etc. Also are you aware of a new Studio driver with optimized V-ray and Blender [1]? Did you already check it?

Thanks for letting us know about the workaround! Closing then.
