Cycles GPU Optix Error; INVALID_VALUE in optixAcellCompact(etc.)

Since Blender 3.0 I keep getting this error in some of my scenes when rendering with cycles.
I have a GTX 1080 so Optix is supported.

Does anyone know why on some of my scenes I get this error and on some I don’t?

Really simple scenes are a go but as soon as a scene get’s mildly complicated it stops.

In my testing anything GTX and Optix isint really beneficial, infact in most cases it makes rendertimes slower…

More officially though, OptiX isint designer for 10 series cards. OptiX is more of cards that have RT cores of which 10 series doesn’t have.

What I would do to fix the problem is to just use CUDA.

It looks like blender is trying to find something that’s not there, hense the “Invalid_Value”.

I get this error whenever I am out of memory with my pc. So I’d assume this is an issue with the lack of memory of your gpu or ram overall

I got 32gb of ram, so yeah maybe that’s the issue. I hope it’s not my gpu since I can’t afford a new one with these prices.

Actually I did try same blend files with previous versions, there Blender can find the Invalid_Value which is GPU out of Shared Host Memory. So problem is definitely GPU VRAM
