Iray rendering with CPU in 4.12

OVD

I thought I was imagining it at first, but it felt like rendering in Iray in 4.12 was taking longer than it used to. But now my other computer tasks are choppy while renders are going on, and I'm looking at the render script and seeing this: 

Rendering in NVIDIA Iray

Compiling Shaders - 0/1

Rendering...

Iray [VERBOSE] - IRAY:RENDER :: 1.7 IRAY rend progr: CPU: Processing scene...

Iray [VERBOSE] - IRAY:RENDER :: 1.9 IRAY rend stat : Native CPU code generated in 0.387s

 

I don't know a tonne about CPU and GPU stuff, but it seems to me that this is rendering with my CPU rather than my GPU, even though I have it set to render with GPU only. 

Can anyone give me some advice about what's going on?

Aight, nevermind. I figured it out. I just needed to update my video card driver. Lesson learned!

Yes with the new 4,12 version of DAZ an upgrade of the graphic card drivers (for Nvidia) was needed, on mine I go for 436.30 version
Without updating the GPU option disapears.
Also with 4.12 I no longer render on the GPU for the geforce 860M, when I do an Iray only render on the 860M (windows 10-60 1903) it now show a high CPU activity and no GPU works.Both on windows and in GPUZ.

Is now this generation of GPU has been banned from the new Iray of DAZ?
