Vray 3.50,04 change to CPU, on VrayDenoiser and Lens Effect. cant use hardware accelerated.

Any idea? :face_with_spiral_eyes:

Does the machine has any discrete GPU? If yes, try installing some recent drivers.

Ty Savage309. I m using gtx driver, the last build. this error starts after vraylicense server update. i know, its only server, but starts after that. I try reinstal, format, update driver. i m was thinking this error was normal to last updade. when i try call ocldevices on vray folder. he says something about opencl.dll;. but i have this file working normal on system.
hardware acceleration make all diference on speed renders.; Maybe 1070chip is not working properly;

If the ocldeviceselect tool says something about OpenCL.dll, it definetely means that the drivers for some reason are not installed properly. Have you restarted your computer after installing the drivers?
