ah it is not useful for image to video

F

Furkan Gözükara SECourses•3/16/25, 1:50 PM

only for video to video

with new preset is using 15,6/15,8. It's fixed

the gpu usage is more constant than before

yes the lesser RAM usage the more GPU usage

and it's faster than ever

JaviEM•3/16/25, 2:07 PM

huge update

it's getting even faster. I have never seen less than 40s/it

@Dr. Furkan Gözükara can you fix the profiles with FP8? It's even slower than bf16 now. It's only using 13GB VRAM and 64% GPU

JaviEM•3/16/25, 3:01 PM

FP8 videos are working fine now btw

time to update the app

J

JaviEM•3/16/25, 4:07 PM

I have updated but preset doesn't change for FP8. 16GB preset still use 3,500,000,000 on FP8

JaviEM•3/16/25, 4:21 PM

With 7,500,000,000 is using 0,4GB of shared VRAM on a 16GB VRAM GPU. I will try lowering it to 7,000,000,000 or 6,500,000,000

FP8 has no sense on a 16GB VRAM GPU

10 videos generated this afternoon and no glitches or image corruption with teacache. I only had one big colour change with FP8. Very nice updates today.

@Dr. Furkan Gözükara are you using the new use_ret_steps in your implementation of teacache in wan 2.1? According to the developers it has more speed and quality in generation
