Can confirm, 2 to3 fps here (running the compr. version)
I
am running a potato though, that also struggles with some of the Ren'Py games.
I believe that's mostly related to 60 fps material. I believe VP9 vs. VP8 can also make a difference (the latter having better performance), the resolution & bitrate matter o/c.
I checked a couple of videos in my media player, where they run perfectly fine (esp. with dxva enabled). I did see some really nice, sexy animations w/ good physics (clothes, boobs, hair) (plus sfx+moaning). I think it's VAM?
Seems vids are rendered with different settings. VP9, 30fps, but different resolutions.
This one vid was 1724x1080, ~3300-4300 kbps, another was 2560x1600, ~5000-8000 kbps.
Note that I was running Bob's compressed (not sure how that processed the originals).
I already knew Ren'Py isn't optimized for video playback (relying solely on the CPU I believe, does a poor/unoptimized job at scaling I believe) (and may never be optimized for that; the author said that it has no priority for him, being a VN engine), does the same apply for RPGM actually (I have less experience with that)?
So nice animations (overall, and some things in particular) with moaning & sfx. Not perfect though. E.g. the pussy licking (eating) sound in some vids was pretty horrible/uncomfortable/off-putting I must say...
Also MC's face/tongue was missing the mark a bit for me there.. (May be a cultural thing though (the way pussy is eaten
))
So I played it for a little, and it's just not ready. Bad translations, text not fitting the box, running off-screen, still Chinese text here & there, the video playback issues (maybe only for those on potato machines?) ...
