Blender doesn't detect CUDA/TitanX After updating to Blender 2.78 on my other PC it does not detect the GPU. It is running on a Win7 x64bit system, card in question is a Maxwell TitanX, which from the official Nvidia spec list is a 5.2 cuda supporting GPU.

Here are some screen caps after doing a clean driver install.
@Hendriks3D Yes, it appears to be a Blender error. Something appears to have went wrong with the files and Blender wasn't detecting the GPU.

After a clean install everything is running ok. Do not know why it worked now and before it didn't work.
