Hello, I follow this course with GPU rendering. All went fine until now, with SSS and experimental features it crashes : out of memory exception. The problem is that the scene is about 500Mb and I have a GTX980 with 4Gb vram... so it shouldn't go out of memory. I have checked my GPU load and it fills indeed the vram before crashing. If I render with CPU the RAM taken is about 500mB, the same as indicated in blender. So why does it take so much vram on the GPU and how to avoid that ? I have also checked that this problem occurs even without SSS and experimental features : I hit 3.5 Gb of vram load so it doesn't crash, but it's far from the 500Mb of the scene. The vram allocated to other processes than blender is about 400Mb, so the memory leak doesn't come from here.
