Reset GPU When Studio Drops to CPU Render

cheznous2029_28ab1adedc

I have read discussions here about the problem that exists when you are trying to do an IRAY render and the program drops to CPU to render due to using up all the memory in the GPU card.

My question is how can you reset your GPU so that you can go back to having a NVIDIA card do the rendering?  I see here posts saying that closing the DAZ studio program and restarting will do it but on my machine this does not work!  Also this problem is encountered on my machine when the GPU is NOT full, at about 6.2GB for a 1070 card with 8GM VRAM.  Also before you tell me to close preview renders, I DON'T HAVE ANY OPEN!  The DAZ program drops to CPU render with as little as 6.2GB VRAM used.  Oh and I also don't have my monitor plugged into the same video card either so that's not an answer!

My fix so far has been to run a benchmark program like UserBenchMark which does a test of the GPU and then resets it.  Sometimes this even does not work!

Unfortunately Windows reserves memory for the displays that could be connected, even if there isn't one currently connected, and Windows 10 also caps the amount of GPU memory any single application can use.

If closing DS doesn't help you will need to shut down and restart.

Windows 10 reserves 10 percent of your GPU. So that leaves you with 7.2GB and then no one progran can reserve more than 90% of the 7.2GB which leaves you 6.48 gb for Studio out of 8gb.

You have 2 options. get the free utilty to resize textures or switch to windows 7.

You could try reducing the texture weight in your entire scene - https://www.daz3d.com/resource-saver-shaders-collection-for-iray

Try running a dforce sim on your card - I've noticed that working quite often. (Also make sure all render windows are closed.)
