Maya Arnold 6: Insufficient Device memory GTX1060 6GB

ARTEHAGA

Does anyone know how to fix Arnold rendering Error Gpu: Insufficient device memory?
Everything used to work fine for me, and now all of a sudden, doing nothing different, Arnold doesn't allow me to render with GPU. Only with CPU.

Have you installed a new graphics driver. If yes you need to repopulate the gpu cache.

I had the updated drivers already. How do I repopulate the GPU cache? what does it mean? 
Would this affect my other applications? 

Thank you very much for your help.


I hope this screenshot helps.

I found the pre-populating option in Arnold. And I do prepopulate but the problem still there. I noticed that if I open a new project the GPU rendering would work fine, but in this one where I am making my face it would never work. I did also delete the cache files before doing the prepopulation.
What if this GPU prepoluation for? there is no information on google about it whatsoever. Frustrating.

Optix does need precompiled shaders to work as expected. And if you change the nvidia driver or the Arnold version you have to redo the cache.

Are you on the latest Arnold version?

Is there hair in this scene?
Displacement?
UDIMs?

You have only 6gb Vram.

I am not in the latest Arnold because I wanted to have a stable Maya, 2018.6. the only Arnold version with GPU rendering that works with it is the 6.0.2.0. I do have hairs and Displacements and 3 more maps etc..
What would you suggest I can do?
I probably give up and just use CPU rendering, but the problem is that my CPU is burning and sometimes crashing my computer.
Thank you very much, mate.

First i would try to lower the subD for the Displacement.

Maya 2020.1 is stable here for me. Using it every day. 
Plus the creases are fixed in ths version.

Thank you for your help. The displacements option didn't work. I guess if no one offers a solution in the entire web is because there is not a solution but updating your graphic card for a gtr 2080Ti. .. Or possibly updating Maya 2020.1 with the latest Arnold.

I believe this page of Autodesk recommendations can help.

I am trying all of this now and will report if it works any of these.
