Yes and no, because someone maybe facing my issue with 4.10+ models, for MKV (especially HEVC coded) containers, where 4.10+ models provides improper frame handling!
I mostly have AVC encoded files but I do have a couple of HEVC encoded files which I regularly use as part of my testing and I haven't seen anything obvious.
Also one more thing, yesterday I tested 4.15 lite and see one artefact, which 4.9 is properly mask! The lite models are less precise I think?
What I noticed was that I saw less artefacts with v4.15 when using TRT 9.2 than using TRT 8.5.1. Meanwhile 4.15 lite/72fps is still pretty good. I'm wondering if it is to do with the other changes I made to the scripts which I reverted back to default. I'm happy with 4.15 lite but I might do some experiments to see if I can improve it further by modding the scripts again.
