f337feaShort description of error
Upon entering render mode or starting the final render, about 2 seconds in the GPU crashes with the following displayed:
CUDA error: out of memory in cuArrayCreate(&handle,&desc)
I know that my GPU should be able to handle this scene as it has 2000MB of video memory available at any time, but the error shows up only when Blender reachs 900MB. I have no other programs open, but the display is in fact using the GPU rather than CPU.
Exact steps for others to reproduce the error
I don't think it's possible to reproduce the error without the same exact graphics card and display drivers, but I have tried to render the scene in other versions of Blender, but to no avail. Here should be the project:
untitled.blend
untitled.blend1

This doesn't look like a bug unfortunately. Cycles requires a certain amount of working memory, which can be hundreds of megabytes, and the operating system will also use a significant amount of memory. This memory usage is not displayed in Blender, but can make it possible to run out of memory when rendering.
We're working on reducing the Cycles working memory, though even if we get that lower you still won't be able to use the full 2GB, for that you would need a separate GPU for rendering and for display.
More technical details in #46928 (GTX 970 memory issue), but basically this is not a bug but something that is something that we continuously try to optimize, like reducing render time, but will never get to zero.

Hi, can please upload a .blend with packed textures?
Without it only use 575 MB on my headless GTX 670 2 GB.
Do you have another card for display?
Windows use 3-400 MB alone.
CHeers, mib
