Oh my gosh I feel so dumb. Its because I've been still using 4.10. As soon as I upgraded to 4.12, the issue went away and Iray can now do ~1000 iterations per minute

I downloaded and installed CUDA 11.1, but still getting errors :(

This might be the issue:

2020-09-20 15:48:38.831 WARNING: dzneuraymgr.cpp(307): Iray WARNING - module:category(IRAY:RENDER): 1.0 IRAY rend warn : GPU 1 (GeForce RTX 2080 Ti) with CUDA compute capability 7.5 cannot be used by iray photoreal. 2020-09-20 15:48:38.831 WARNING: dzneuraymgr.cpp(307): Iray WARNING - module:category(IRAY:RENDER): 1.0 IRAY rend warn : There is no CUDA-capable GPU available to the iray photoreal renderer.

So with both CPU and GPU checked, it takes roughly 20 minutes or more to fully render a scene with only Victoria 8, and nothing else. Does that sound normal? It seems really long to me. All my drivers are up to date, and I'm using default render settings, apart from the check boxes for CPU and GPU.

Is it possible to utilize both CPU and GPU? If I select both in settings, Daz only uses my CPU. Is that the bug you mentioned?

If I select only my gpu, nothing renders in my window :(

I was told for use with Genesis 8, you must use the second zip file... lola69_BreastJig2-0_DS_Plugin_240088.zip. The other one does not work with g8. Also, I have email the vendor for you. You should hear back from them soon.

That is the version that I am currently using, and thank you!

Thank you so much!
