Quote - Can somebody show me how to configure this to use GPU for rendering? Mine bombs out. Don't think I set it up properly. Screenshots of the interface settings will be greatly appreciated. I have an i7 with 16GB ram using win764 and my GPU is an nvidia Geforce 560 TI. Thanks:)

 

There's really nothing to configure.  I've never figured out why, but sometimes it works and sometimes it doesn't.  Nvidia users need to set OpenCL workgroup size, but that's the only setting to change.

I googled "gpu rendering reality" and there are a few discussions out there covering multiple issues. Sorry I can't help more.  I gave up trying with GPU and SLG.
