Anyone else notice this problem?

Has anyone else noticed that with Daz Studio 4.11 Beta, you have to sometimes quit and restart the program several times to get it to render with the GPU only, rather than dumping to CPU? Or is it just me?

Depends on your scene and how much you are trying to load on to the GPU.  If you have too many textures, a lot of 4k textures or many instances in the scene, you may find yourself having too much for the video card ram to hold.

There are different tools available to help reduce the load on your video card:

I actually figured out the problem; it wasn't an issue with scene optimization. It was a problem with the viewport renderer. Whenever the viewport was in Iray mode it was rendering with the GPU no problem -- in the Viewport. But when I would push "Render" it would dump to the CPU. But when I would turn the viewport back to Wireframe mode, or any other mode other than Iray, and push "Render," it would then render using the GPU only instead of dumping to the CPU. Weird, eh?

When you use theIray mode for the viewport, then chose render without changing the viewport, I believe the GPU VRAM is not "flushed". Same as having many render windows open. You are filled the VRAM and forcing Iray to drop to CPU mode.

Not having this problem in 4.10 with a GTX980, or a Titan X (Pascal), or a 1080ti. Is it a 4.11 issue? I leave the viewport on the Render tab set to Iray since it pre-compiles everything and starts the actual 1920x1080 render faster.
