  • GPU Acceleration out of mem

    I'm using Vray3.4 for Rhino 5.

    My renders are being automatically aborted after the engine claims not enough memory on my GPU.

    Preparing Render -> Running RTEngine -> Detects my GPU (GTX-1070 8GB) -> identifies total memory 8192MB, 7163MB free. Does all the prep for Primitives, Meshes, Tree nodes etc, and starts loading textures. Then it builds optimized CUDA kernel, then tells me Total memory for device is 8192MB, free 178MB.

    I get the message ./src/oc1_tracedevice.cpp(3012) : CUDA error 2 : unable to allocate enough memory to perform the requested operation (out of mem) in red, and then render is aborted.

    I will admit the file&renders I am doing are quite complicated, but is there a way to utilize my 16GB RAM on top of the GPU memory? Or is there something else I could be doing?

    Thanks!
