Iray on AMD cards

superesp87_58361490f5

So the reason my PC gets all wonky during my renders is because Iray forces into the CPU due to having AMD? Well, that is a show-stopper for me because it messes up my PC. I want an alternative to Iray that does support my AMD GPU, because otherwise I can literally not use my PC to render.

Problem is, Iray is a render engine made by nvidia. That is why it only works on nvidia cards.

Use Blender and cycles; you can use either card there.

I also found cycles to be much better using the CPU than nvidia.

The Advanced tab of render Settings does allow you to tell Iray to use only a limitied number of available threads, which should stop it from locking the system even with Iray.

In the iRay setting go and

1) Optimize for Memory

2) CPU affity change it to only about 1/2 the CPU cores you have available.

Your PC will still crawl on some renders until DAZ Studio/iRay finish building the renderable scene from your DAZ scene but once it starts rendering (usually less than 5 minutes, certainly less than 10 minutes, for 99% of the scenes you'd make) you can use your PC still. The render will still take 4 - 48 hours to render to 2000 iterations at FHD but that's been true of rendering without a specialized GPU that the render engine was built for from the beginning of ray tracing.
