Viewport Lag

JohnDelaquiox

I recently built a new computer.

The specs are as followed

Ryzen 1700 8Core 16Threads running at 3.5GHZ which Trubos up to 4.0GHZ

32GB of Corsair Vengeance DDR4 Running at 3200 megs

Windows 7 Pro 64 Bit on a 250GB M.2 NVME from Samsung

I have a 500GB Samsung EVO SSD dedicated to Daz Content

All of this is running on an MSI X470 Gaming Pro Motherboard. and a 750 Platinum Pro Power Supply from Be Quiet.

And the viewport still lags, with optimization on or off.

I am planning on upgrading my CPU to either a 2700X or 3900X and adding a second GTX 1070 8Gb

Can someone please tell me why the Viewport may still be lagging.

I assume you mean plain viewport mode, not Iray preview?

After viewport lag in DAZ Studio 4.10 made it nearly unusable, DS 4.11 & the DS 4.12 beta have a pretty quick viewport again. What still lags is when I put a fibremesh hair on a character, then often the viewport will lag when I try to change something on the character. I guess I should stick to using polygonal hair or learn how to make SBH myself that fits my wants.

Taoz Both actually.

While the 1070 is pretty fast, it's still not enough to fully render a scene really fast.

I was experiencing the same thing the other day suddenly. Check the bottom of your scene. Is there a smoothing modifier constantly loading? I've found that when a saved scene is loaded the smoothing modifiers will sometimes get wonky and constantly refresh. After that you have to remove and readd them to get it back to normal.

When they are constantly refreshing even my 2700x ryzen + 2080TI lags in the viewport.

 

Just an idea!

P.S. I'd wait and get the 3900x over the 2700x :)

I had been using Daz for a number of months when I first started using it with this same problem, particularly when I would add hair to a character. I forget where the setting is at, but I had changed it to "Best" and it took care of the viewport lag when in Texture Shaded view. After that, I've been able to use all of the hair products I have without viewport lag.

I have a GTX 1070 myself, and manipulating the viewport goes pretty fast even with 10+ year old hardware (PCIe 1.1 board, 2.4 Ghz Core2 Quad, 8 GB DDR2 RAM, HDDs only).  And that's both in 4.10 and 4.12. I was just testing Streets of Asia 4, fairly large scene, and added a couple of G3 characters with OOT hair and clothing plus a car; scene is spinning around, no lag at all.  See video: https://www.screencast.com/t/J3bGTEe62JE

Here's my viewport settings:

In Iray preview mode that scene is pretty slow to manipulate though. With most scenes (depending on size and content, works best with smaller scenes it seems) you can increase the speed though using a little trick: create a small render (100x100 px (to keep memory use low) is enough) of the scene in a separate window, and keep it open in the background.  That apparently keeps some stuff permanently in memory so it updates faster when you manipulate the scene. 

DrawStyle settings also affects Iray preview speed, here's the ones I use:

That was it, "Display Optimization" --> Best. That's what I had changed.

First I want to say thank you to everyone who shimed in.

After having spent sometime with this new build I've decided I'm going to swap motherboards, upgrade to a 3900, and add a second gtx 1070 as it really seems like the most affordable way to boost performance.

A single gtx 1080 ti is still too much money, even used, and all other cards are way too much. I can get a second gtx 1070 for $200.00 and when paired with mine, should give me the desired performance.
