VR and Large Images

[Kurtista]

What's up everyone!

I noticed @C0untFloyd did an update for VR Mode and I wanted to mess around with it. I noticed a huge performance drop off as compared to my normal videos (1080p mostly). I think this is probably just due to the sheer size/quality of image frames since VR is a huge double 4k type image and wanted to sanity check. Has anyone done normal 4k videos and ran into something similar?

Settings:
GPEN
8 threads
using 19-20GB/24GB of video memory (checked on gpu-z using a 3090)
Currently runs at about 2fps.

Cheers

Every thread processes a frame, it might be you ran out of VRAM. Did you try with a lower number of threads or even just 1 for a start?

Tried with 1 thread and it seems that speeds it up by about double! 2 knocks it back down a bit. Weird cause its not getting even close to going through my VRAM. I have 24GB on the 3090. I see someone made a benchmark thread, might add on to it to get a normalized speed for a 24GB card.

I did a little more digging and extracted the frames. I think its just a tough/long process when each png is over 15mb plus it needs to run the swap+processing on at least 2 faces since the VR is split screen. Plus its all at 60fps! I think my typical 1080p video has frames under 2mb in size and runs ~30fps.

Thanks @C0untFloyd

Glad I could help, sometimes less is more.
