Hello to all Users,
since few days I running in the same situation while rendering or using Nvidia in viewport... starting rendering, but nothing happens and the process is interupted automatically... any idea why? Thanks.
I have geforce gtx 1050ti with 4gb of ram, 16gb ram windows 10 64-bit
The errorlog showing the following

Isn't that what happens when the scene requires more GPU VRAM than you have, and it runs out, and you de-selected the CPU so it can't participate either, so it just crashes? I would check my Task Manager where it shows GPU VRAM usage and see if it gets up near 4GB.
There's your problem, the GTX 1050 only has 4Gb VRAM, not nearly enough for what you need, 8Gb is doable, 10Gb is attainable, but 24Gb is ideal! :)
it's an empty scene withouth background and one character... I did more complex scenes with this card without any issue.
Yes, I am using studio driver... should I try the game driver version?
sure not, it's so when I start Daz3d an load the scene, it starts rendering. When I interrupt the process and want to restart the render, I got the error message as posted above... the same happening, when I make a new scene and want to render.
Check the subdivision setting on that character.
It also sounds like it's not releasing memory for a new scene, what is the actual driver version? (I'm using the 461.09 game driver on a 750ti without problems.)
I don't understand. You're saying that when you start rendering, then hit Cancel in the Iray render preview window and then restart the render you get that message?
Also, how long do you wait before you hit Cancel?
That's what the error logs read, it's right there in the logs themselves, you ran out of VRAM and the rendering engine quit; also, it is most likely that you were using something on your PC that was also using VRAM and DS drained what was not being used...
Yeah, subdivision lvl was at its maximum (3 and 6). After switching it to standart (1 and 2) I've got my render speed back. Thank You, kind Sir!
Thanks much for the information about the subdivision level. I was having a similar problem where my initial render would use the GPU (6Gb) but then would pop back to CPU rendering right after (much slower). I checked the subdivision level on the character and it was set to 4, which was too high for my card. After I dropped the subdivision down to 2, I had no problem keeping the rendering relatively fast - primarily on the GPU.
