2) If you were able to get it to work, would your world be a better place?
3) Would any improvement in throughput cancel the time it takes to solve one GPU render bug?
My thoughts on that:
1) Yes it is. Its mobile (laptop) GPU from Nvidia's 900 series. I believe even the desktop versions have/had issues with Vegas and only specific drivers work. Search this forum.
2) Maybe. The reason I say that is that I can't find the exact spec for the GPU. It's based on the GM108 chip and may have 384 CUDA cores, not a lot but should help; it also supports OpenCL 1.2 and NVENC.
