Reality 4 with Daz 4.8 and Nvidia Graphics Card OpenCL Group Size

Wanderer

I'm sorry the title wasn't very clear. I couldn't think of a good way to put it. I am very noobish at this, so please forgive is this isn't useful for others the way it was for me.

I have Reality 4 installed with Daz Studio 4.8 Pro running on a Windows 7 Ultimate/64 bit installation. Hardware is i5-2500k @3.3 GHz, 16 GB RAM, and GeForce GTX 680 w/ 4GB Total Available RAM but 2 GB Dedicated Video RAM. I thought my system should be OpenCL compatible, but every time I attempted to run Reality with Hybrid GPU setting enabled, the log would indicate that it could not be run and the render would fall back on CPU only. I read over and over again that certain Nvidia cards required 64 to be entered into the OpenCL Group size setting, but this did nothing to resolve the issue, so this afternoon, on a hunch, I changed the number to 128. It now works without problems. So if you're having issues with using Hybrid GPU enabled in Reality 4, but can't figure out why it isn't working, maybe give this a try. I hope this helps others. It really helped me.
