Major performance issues.

Mescalino

I used to be able to render this in 10 - 20 minutes. As you can see its not a complex scene. I also noticed that Daz eating up extreme amounts of ramm. This scene is taking up almost 4GB ramm. I noticed this when i updated Daz afew days ago. Does anyone else have this issues or some suggestions. I ran my virus scanner and mallwarebytes but nothing serious came out of it. 

 

I am not a complete noob with computers but i am at a lost here.

How are you lighting the scene? Do any of the figures have HD moprhs applied? Have you tried enabling Progressive Rendering in Render Settings?

The main character has some morphs to her body but she never took realy long to render. The rest is prety standard. I just tryed enabling the progressive render settings that helped in the performance but the render looked realy horrible. (like an 8-bit drawing) so i stopped at 50%. Also it didnt seem it was progressing after that. i am now playing with the lights.

I tried rendering a different scene that was rendering fast and that one was fast so it must be a setting issue.

I decided to let the progressive render on run to its full 100% and that did save me a lot of time though the las 25% seem to last forever.... it was stuck on 75% for 7 to 10 mins. so i had to stop it prematurely

But it did give me some insight on the various settings. May have to  play a bit on the Anti Aliasing settings but that will seriously increase render times....

On a side note:

I do have one scene i really hope to get a few renders out but its a yoga scene with 12 students and a teacher so that means 13 models with 13 hair types and 13 yoga suits (in 3 different types).

What is the image size (dimension)

What kind of surface shaders are you using?

Are you using standard lights or Uber environment lights or AgeofArmor lights?

My first thought is a corruputed scene file. You might want to make a copy, then start deleting parts of the scene and see if there's something that's causing the problem. 

My other thought is maybe it's running out of VRAM in your video card (if you have one), and is dropping to the much slower CPU for rendering.

Well, thats what it does ;) it samples 1 pixel out of a grid by for example 8x8 pixels and render an 8x8 box in that color, so it renders the first pass 63 times faster, then it starts over and split up each 8x8 box into 4 "pixels" and so on until it reach a 1x1 pixel size, so it will look ugly until it is finished, but it gives you a clue of what it will look like.

Anyway, what is it that slow it down ? you can see on the buckets where it is sitting for long time (usually hair and face), or is it slow everywhere ? play around with shading rate, if you set it to low it will make it very slow and not improve the quality much.

If the scene worked fine before then it should work fine with the update as well. Check the log and see if it reverts to cpu for some reason. My guess is that you didn't update the video card drivers when you updated DS.
