Short description of error
Most scenes, perhaps the bigger ones, stops rendering immediately with
"CUDA error: Not found in cuModuleGetTexRef(&texref, cuModule, bind_name.c_str())"
in viewportrender and F12. Same scenes render fine until 2050ecc.

This error doesn't happen if a "config" folder is created, so factory settings are activated.

It's not the first time, I had to renew my startup.blend and userpref.blend, though with the same settings ...
