I’m getting some pretty slow frame rates.
I’m running a Q6600, GF 8800GT, 4GB RAM and using Vista x64. When running a scene with 30K polys I’m getting about 6-16 fps. And this is without ‘Edged Faces’ on. When “Edged Faces’ is on, I’m getting like 4-6 fps. This is pretty damn slow and I don’t recall the same performance with 2008.
Also, the PC I’m using at work, which has an inferior GFX card and is running XP 32bit, is running scenes with twice as many polys at a better frame rate. I use Max 2008 there.

So is this a known issue with Max 2009?

I’m experiencing the same thing. I’ve just been to busy to mention it.

It seems that OpenGL performs much better then Direct3D. I ran a benchmark of a camera circling my scene and Direct3D’s range was: 8-17 fps. OpenGL was 27-34 fps. This is pretty surprising as I thought that Direct3D was preferable when it comes to GeForce cards and it is also the recommended driver to use within Max.
In anyway, I still would prefer to use Direct3D so if anyone has an idea as to what is going on, I’d really appreciate it.

Hmm. OpenGL should not be the fastest mode unless in wireframe. DX is a heavily optimized mode for us. DX pays a performance penalty in wireframe, but it generally will still be faster than OGL since people rarely do just wireframe. I would make sure you have the latest drivers for your hw. I would also look at disabling the viewcube because that has had a performance impact on the rare system. Also, make sure you’re using latest SP as we fixed some viewport issues in that.

I think I have the latest drivers but I’ll double check. Thanks!

I do have the latest drivers for my card and I have disabled the viewcube and it didn’t change a thing.
I’ll get the latest SP and check to see if there’s any difference once I get home. Though I read that for some people with a similar problem, applying the SP didn’t help.

This is pretty weird.
I did a little test and created a number of spheres in an empty scene which together had just above 1 million polys. The frame rate was 100+. Then I returned to the scene I’m working on which has a model composed of about 2800 polys. The rest of the scene is a couple of planes and a box. The frame rate there mostly is mostly in the 40’s. Though it goes as low as 13 and as high as 90+. Whats so special about this model that plummets the frame rate?? The tests were with the viewport set to ‘Smooth + Highlights’ only, no edged faces. Installed SP1.

Just switched from Max 9 to 2009 last week.

I open a scene with about 150k polys in the entire scene. Using layers I have about 9k Polys visible. Gradually over time the FPS drops from 100+ to below 10 and sometimes even worse. Takes about 20 minutes. I read on other forums about this problem but no one seems to have a solution.
If I open the scene and just move around in the viewport without editing anything, I can see the FPS drop. Maybe its related to the undo camera change option? (Shift+Z) Does anyone know how to stop Max 2009 from saving your previous viewport views? Just a guess.

The only thing that helps is restarting Max every 20 minutes. I’ve noticed if I turn off Edged Faces and just use Smooth + Highlighted, the frame rate jumps to 20+FPS but as soon as I show edged faces its back down to below 4FPS

If I go into just wireframe view… 8FPS.

System Info
Max 2009 - SP 1 and all current hotfixes
Windows XP 32
Geforce 9800 GTX (Video Driver 178.24)
3GB Ram - Intel Core 2 Quad @ 2.8ghz

Tried both OpenGL and Direct3D. Same performance problem.

I’m not so sure that the problem you guys are having is the same as mine because my poor performance issue is constant and does not resolve by restarting Max.
So I think it would be better that either of you will open a new thread.

Hello everyone! Having the same problem. I’ve made some tests of max 2009 with DirectX on XP x64 . The most frustrating of all, appeared when I animated a camera(path constraint) and played in viewport. After few repeats the memory that max begun to use, was like I eat pancakes :-) It consumed all available memory(6GB RAM+9GB Page file) and from 100fps dropped to 0.5fps.  Repeated the same scene on max9 ->every thing ok. Same test with max 2009,but with OpenGL-> everything ok. Same test with max2009 with Directx,but deactivated all maps in viewport-> everything ok. I ‘ve sad: Well, No so bad :-) But after 1h hour work(max 2009,Directx, Deactivated maps) fps drop, appeared again.
So the only thing that work for me was using OpenGL. Unfortunately, it is to slow in some scenes.

I hope HotFix will be available for this unacceptable issue!
