Incredible (bad) 3ds max 2011 behavior: LAG viewport!

[cecofuli]

Hi friend,

This is my first time that I see this problem in Max, but I 've tested in 3 different machines and I've the same behavior. My WS is 560 GTX Win7 64bit + Max 64bit obviously.

It's the the famous "2-3 second lag" in the viewport.
I think this second needs to 3ds max to put the data on the GPU memory. Ok, but... see my screenshot!!!
The file is a exterior model. I don't know who model this file. But all the meshes are very bad. double face, open edge etc... Ok, no problem. The polycount is not so big and no texture. Just color. But, this is not the real problem. Ok, it's MY problem ehhh, but not for that discussion




When I use the mouse+keyboard combination to orbit/move/zoom, I need to waiting 1-2 second every time. Very boring behavior. But If I use the "Orbit icon" (the button on the right - bottom of 3ds max user interface) the yellow circle appears on the viewport and... It's a MIRACLE! No lag !!!

Same behavior if I enter in some sub-object mode (vertex, edge, face etc...) for any mesh . for example, in my video I use a simple sphere.

Why this unusual action?? Any idea
I use 560 GTX and 9800GTX and Nvidia 8400 fanless (ehh...) but , same problem. I use a 3ds max viewport default setting for the DX.

you can try yourself with my simplified max version (Max 2010)

do you have your cube disabled? I don't see it, so I assume you do.

[glorybound]

But all the meshes are very bad. double face, open edge etc...cecofuli

Must be a Revit model

[cecofuli]

Obviously, yes

Not only disable, but also deleted on 3ds max stdplugs!

Is your Windows graphics set to best performance?

[glorybound]

I remember someone posting awhile back, about converting everything to an editable poly, to speed things up.

[cecofuli]

Thanks glorybound. Yes, best performance.
I remember too if you put on the top of the modifier stack and edit mesh you can speed up, but it's not a useful solution, when we have a lot of geometry.
And, why with orbit mode I've a very good performance :/ ??? This is the question!

Did you see if it had Back-face-cull on object properties??? When ON it seems to give this sort of lag on large scenes.

Hope this helps

[cecofuli]

Yes. It's OFF for all

[cecofuli]

Another suggestion. With my sample file, try to use for the pan the "PAN" icon on the right-botton of UI of 3ds max and, next, the middle mouse. See the difference in the lag. It's incredible and I don't understand why this happen... :/
3ds max bug? Nvidia bug? Can you try with some Quadro videocard? Or different OS/MAx version (32,64bit, XP, Vista etc...)

And, if you want to make the viewport more heavy, try to copy 10 times the geometry in COPY mode. I've 3-4 second lag with middle mouse PAN, but no lag with PAN icon O_o'

[cecofuli]

Ok, it's a max BUG!

Here's two more reasons I have had graphics issues similar to what you are experiencing

---What is your scene scale??? I have had troubles with large scenes that are in mm units.

---Is your model a long way from world origin..0,0,0??? Have had issue with this as well

[cecofuli]

You can see the file setting yourself, with my sample.
Anyway, the models are very close to 0,0,0 and we working always in cm.

Try attaching as many revit objects as posible to reduce a number of objects in database. For example, attach all window frames into one object, all glass objects into one object etc...I usually do this on "per material" basis.
Your video card will thank you for not having to deal with 50000 objects but only 500
Hope this helps

Hi Zoran ,
I know that, but, if you open my sample files, it's just one piece of mesh. If you duplicate 10 times the entire poly, the viewport will be unusable It's a 3ds max bug unfortunately...
