Go to Render Settings (Window > Pane (Tabs) > Render Settings... what's your ram like, etc.
I have 64GB RAM, 2x 2TB NVMEs. Daz data is on half of one of those drives, the other is my system storage. And I have those render settings.
Or do you mean, moving a limb/head/joint causes the viewport to stutter/freeze up? If the former, it's going to do that regardless of hardware. It'll usually be slightly sluggish, but never crippling. The latter?...
Yeah, this. For the sake of consistency going forward, let's assume I do everything with Texture Shaded at best.
In Blender I've gotten used to how quickly things load and how transforming/rotating joints/limbs in Eevee. It's instant, and I can watch animations even where characters and their clothing are colliding. In Daz, if I delete the hair, clothing and textures off my models, I can properly pose them. But if I hide them from rendering, it's drag, wait a second, drag. It's hover, wait a half a sec, hovered. I don't know if this is normal.
I don't know exactly how people set up scenes, but I like to use keyframes on the timeline to sequence my renders and see how they'll look in a sequence, from image 1 to image 10. For example, lets say I have 2 characters in a room. I'll keyframe the poses of each character for image 1 and 2 on frames 1 and 2, but the more frames I add, the slower bending/rotating joints becomes until DAZ locks up and freezes. Once I get to 8 frames, I've needed to create a separate save and delete all but the latest keyframe, then reload the file so I can continue to pose my characters in the scene. I don't know if this is normal, or if there's an easier way, but this is my biggest issue.
Other than that, I guess what I'm asking is, are you able to preview animations in the timeline?
...Ever? Like, down to barebones, untextured DAZ assets?
If I want an animation preview I have to render it, because the preview is maybe 0.0001FPS if I'm lucky.
