About the rendering time

foxyfoxfurries

Hello everyone! :)
I have graphic card 3080 TI Asus and it works great! When I start rendering it works very well at the first time , But when I see something I need to fix I change the character pose start tendering again and even when its 10min its on 0% , And at the first time I enter DAZ and start rendering the time in 10min its like 80%+-... If I want it to render fast again I need to exit DAZ and enter again and it works well but if I stop the rendering and start again it will have the same slow rendering...

Any one know maybe whay this is happen?
Thanks :P

You are probably going over the VRAM limit after the change. Not completely sure how it works, but the VRAM does not get emptied after a render. When you restart you will have more empty VRAM you can use. It helps to set the viewport to a more basic setting like textured shading, that will leave you with more VRAM to create the render. You can of course also use a smaller reoltution for your render so that it eats up less VRAM.

If you save a scene, create a new empty scene (File/New) and then reload the saved scene (File/Open), will the used VRAM have been released?  Thanks.

Not system RAM, but vRAM on the GPU.  I forget how much a 3080ti has. Iray doesn't really clear out vRAM all the way after a render sometimes.

OK.  Thanks.  I'm a hobbyist (now retired) with an RTX 2060 laptop system (16 GB of RAM and 6 GB VRAM) .  I'm not a heavy-duty user but it's always good to know stuff.

jjoyner I'm sorry, I was commenting on the OP.  MY answer does not apply to your question.  It's the vRAM that often does not get released until DAZ is closed completely and restarted.  foxyfoxfurries seemed to be misunderstanding a previous answer and was referring to system RAM, which with 64GB is likely not the problem they are having.

Got it.  Thanks for your update.

Oh ok thank you! I found a way to let the PC rest 5 minitues +- and then rendering again and it works amazing lol xD
