GPU crashes on certain Iray renders with new items.

Have a new computer built, asus mb 6 core running at 3.98 ghz, 16 gb ram Nvidia 1660 TI SC gpu. 

Upon loading the Lingerie robe set for G8 and attempting a render on G8 , Basic rernder my Gpu crashed. With out the robe the Gpu worked fine.

I have tried multiple scenes much more complex and even Genesis to render but in this last few days they all now revert automaticly to CPU or take hours to render an active viewport render. 

The GPU checks out as working fine and up to date on the drivers. Did Daz make any changes to 4.12 this last week? 

I have literally went from rendering 3000 x 3000 in 2 hours very detailed and full of items to 1000-600 with 1 fidgure in 2 hours. 

Maybe getting a 1660TI was a waste of money?

Check that your driver hasn't reverted to an earlier version thanks to Windows Update.

The version of iray in DS 4.12 is using OptiX Prime for non-RTX cards, such as yours, which does consume more memory than not using it. Also, if you have the Denoiser on that will consume memory once it starts.
