Yes, this happens a lot to everyone. Your graphics card is running out of memory, it doesn’t have enough to hold the scene. The solution is always the one we don’t like to hear, I got to get myself a better computer now. It’s just the reality of computer graphics, we need beefier and beefier computers. As you say there’s scene optimizations we have to go through so the scene can fit in memory, but when all else fails, we render with the CPU and not the GPU and take the big jump in render time hit.
