Lag in 3D preview

[bassnbuck]

I was wondering if anyone had suggestions on why in my 3d preview that my effects look slower and dont match the timing compared to when you play it in 2d preview.
even when i make the 3d house model inactive it doesnt change.  are there settings on my graphics card that i should adjust?

I've never experienced this.  Can you say a bit more about your hardware, xLights version, and OS?

The computer is an i7 6800k  16 gb ram nvida gtx670 graphics card.  running windows 10  and the latest version of xlights.  i have 3 monitors 2 running at 2560x1440 and 1 1920x1080

What happens if you just have 1 monitor connected?

Hmm...hard to say.  That video card is from like 2012.  I would first try creating an empty show folder and just add one model and see how it performs.

ok i will try it with just one model and empty show folder.  i did try someone setup on my computer and it seem to work fine.  biggest difference was he didnt have as many channels as i do.  should i re-create the models or can i just import one?

I think its easy to just drop a mega tree down in 2 seconds.

so i tried it with just a tree and it seems fine.  seems like when i start adding a bunch of channels that when it becomes more laggy.
i did an xlight export video preview and it looked normal, but it took almost 20 mins to export it.

it looks like the problem was with my layout.  i had a P5 panel that i used solid circle as the display appearance and when i would switch from 2d to 3d the FPS in the sequencer tab it would drop from 19 fps to 3.0 FPS, and that was after i went out and bought a Nvidia RTX 2070 video card.  once i change it to square appearance it was fine. this was test by a couple others in a zoom chat over the weekend.  so it seems like you have to be careful on what appearance you choose.
