Use RAM installed on computer for remove VRAM limitation for large scene and large textures.

I cant believe no-one has thought of that till now

I think the problem is the interface speed between system RAM and the GPU, its just too slow for the GPU demands.

[andrian]

This was discussed and explained many many times in the forum....

[vinz]

welcome vgd

As stated, this has been covered many times over. The speed between the system ram and gpu is just too slow. So slow that it would reduce the speed to that of using the cpu for rendering. Thus losing all advantage of using the gpu.

Ok, but some large image render is impossible with only videoram. I work with large fil, many object polygons, many large textures and large render for offset print. Octane velocity and quality is very important for professional work but VRAM limit use at small printing.

[vinz]

yes VGD, with Vram we are limitred to small/medium print, but each technology have its one advantange and inconvenients.
ptobably in the near futur it will evolve with new hardware

[vgd]

Yes any new technology have some limit. Is possible think to implement a feature for render large image in strips or blocks?
Any strip or block will save in temp file and when end merge it all strips into full resolution image. This method reduce use of VRAM and limit memory render at small portion of final image. Octane real time preview at 1024px remain intact but produce final very large images with less VRAM memory.
Electricimage Universe with Renderama application work in this way for render large image with less memory, but use CPU like many other biased applications.
Right idea for Octane?

[vinz]

for now octane can't use cpu and ram without loosing speed... if i remember well radiance said he will look for a solution for hires pictures, but he have to finish the render engine and focus on basics things.

Yes, strips, buckets etc would reduce some VRam, still the whole scene must be loaded into VRam, meaning geometry and textures; you'd save on the resolution buffer though
