Karma Xpu our-of-core in windows vs linux (strange behavior) April 5, 2024, 2:58 p.m.

i just try to test kamra xpu and i'm notice that if i render the same scene (large scene) in linux and windows It behaves differently

in windows both cpu & gpu working
and in linux the gpu failed

i test it in a few scenes (also very large scene) and all of them are the same (in linux it failing and in windows it working)
(I guess it will be like that for everyone)

why in linux its failing and in windows not? its the same vram .
and if its the nvidia windows drivers why its happening?

( i have 4090+3090)

because its always using materialx

i have a few question
as you know the main use of houdini its in large/huge vfx scenes thats a lot of studios are doing soo so why not take their comments in addition to your students?

Also after i mention that alot of studios using houdini for large vfx scenes ,
you compare redshift against karma with a simple scene and you forgot big big issue soo what happen if you have only 16/20/24gb vram card and you have large scene? In this situation do you still preferred to use redshift?
and how redshift handle large scene compare to karma xpu/cpu or arnold?

and one more question and i guess alot of people want to ask you , can you make redshift vs arnold review?
