Nvil become very slow if you have more than 200 000 polygons. I think it is the main problem of Nvil.... Pleas FIX it!

I have 670,000 polygons and 600 meshes without any lag.


Viewport performance is relevant to your Graphics Card as well.

I am using an Nvidia 460 card...pretty old  card and it is handling things just fine.

I will be stress testing the app with my current project which is going to be 2m polygons minimum.

Mason,
I have NVIDIA GeForce GTX 560 Ti, I7 and 28 GB RAM.

I have to wait 2 minutes to subdivide this model (80 000 polys).

And it is impossible to make subdive of level 2.

I found Nvil very slow in this way...
I think there is 2 weakness of Nvil at this time:

1. It is slow.
2. Lack of Help and tutorials.

Steve,
I tried this and a lot of other stuff that was recommended to me in one of topic I started about this. It is that thread that you posted...
But nothing can solve the problem. It makes Nvil a bit faster but it still stay very slow...

Have you tried the 64bit version, that should help remove any bottle neck around memory.

Yep, I also have no *32 in task manager, so it looks like I use 64 bit version.

I just did a very random test on view performance with around 1 million polys. Ran on a laptop with 8GB RAM, i7 QuadCore @ 2.3 GHz, Nvidia Geforce GTX 675M.
View navigation was still ok. I tried a few different rendering options (hide edges on unselected, hide edges on view navigation, hide vertices/edges). But selection got really slow and unresponsive, even when just selecting objects. I didn't try selection options. Also the recognition of shortcuts didn't work that well anymore.

Because the test was so random, the video is quite long (~8min):

[Edit]: Disabling 'Edit>>Options>>Reatime Selection Enabled' helps a bit.

Vaquero, that is what I'm saying about...
Also as I notice, if you have simple topology like you have in your test Nvil will more responsive. But if you have complex topology it will more slow. Like I say in my helicopter example it hase less polygons but topologŠ½ is complex and Nvil become slow.

Also, imagine you have to work always toggling subd... It is very hard... waiting for minutes to subdevide/unsudivide model...

I believe that the program which is based modeler, the first thing should be different good performance and flexibility

ya navigation is ok for me at 1m polys, but when i hit tab to toggle subd on and off, it takes forver
