View Full Version : Display performance (Maya 5, Radeon 9700)

Hi!

I was trying to build a scene with a lot of instances of a single object (around 1000) and became frustrated about the very low frame rates I was getting when working in the persp panel. My setup is a P4 2.5, Radeon 9700 and 1GB RAM so I was wondering how that could be...

Here (http://mypage.bluewin.ch/miklos/performance-test.mb) you can find a very simple scene (about 1000 poly cylinders, all instances). If a couple of people could download it, switch to 5 (smooth shade) in the persp panel, rotate a couple of times while all cylinders are visible and tell me the frame rate readouts they are getting, I'd be very happy! (Display->Heads Up Display->Frame Rate)

The maximum fps I'm getting is around 5. How can that be? It's only about 80'000 polygons...

Any help is greatly appreciated!

I have P4 2.8 GHZ 800FSB Hyperthread, ATI Radeon 9600 Pro, 1GB RAM, Maya 5. I get about ~5.3 FPS consistently, with the maximum 8.9 FPS.

One really annoying thing about Maya, as you've found is that more objects sloooows down your UI speed, regardless of the polycount (This doesn't seem to happen in Max :shrug: )

I don't have Maya5, so I couldn't see your scene.... But I made 1000 cylinders (probably less tesselation than yours though), and got about 8-10 fps... Then, I combined all the cylinders, and then got about 30 fps (hooray, 3x speed!), so you could try that if the instanced objects are just static objects.

:beer:

Well this wouldnt help much but anyway i tried it too on my
Macintosh 450mhz G4 with 1GB ram and a geforce2 mx 32mb.
I got 1.1 fps before even rotating and 0.7 during the rotation process :bounce: :applause:

Thanks for all the replies!

On one side I'm glad it's not a flaw in my configuration. On the other I'm a bit annoyed that Maya is supposed to be slow when viewing many objects. Rather than throwing in some half-hearted new features they should concentrate on the basics again!

Yes, I agree. I think it's slow already even before you have any complicated scenes. They should also work on and complete mental ray integration until it feels like native.

MR integration is a one of the advertised new features of Maya 5. When you actually work with it you bump into the limitations all the time. If Softimage managed to integrate it fully than it can't be that hard! ;) But maybe we are too impatient and should give them another year...

Or why not integrate RenderMan? They just cut their prices by half. Who could resist to Maya & RenderMan in one package? ;)

I get anywhere from 3 to 5.5 fps. I have a athlon xp 2400+ 512 Mb ram and a radeon 9700 pro. That is supremely annoying seeing it rotate like that. But whaddya gonna do. On that Mental Ray note...I'm pretty new to maya...where can i find a good tutorial on rendering with MR...I can't seem to get it to render scenes that look good at all. Like I said...I'm pretty noob.

If your looking for an immediate speedup while you tweak your system try this:

In your camera view Shading > Interactive Shading >
and change it to something other than normal like: wireframe
bounding box
points

It should help you out till your fix your system prob.

damm. i only got like a max of 3.5 I tried to combine them Maya crashed. then i tried just to do a few first and it still crashed. is there something freaky with your scene or something.

I have 2.4 or 2.5 with all objects visible. The hardware is what you can see in my signature.

I´m using a Athlon 1.4 GHz, 500 MB RAM, NVidia GeForce 4 Ti 128MB with SoftQuadro4 (turns the GeForce into a Quadro 750 XGL), 1152x864, 32 bits color.
Well, I got the same results with 1000 instances (80k polys): around 3.5 fps.
But I got significantly better (5.5 fps) without using instances (real copies instead). And 8.6 fps with combined copies.

maya's viewport renders seems quite slow in general, I always get way better framrates in max displaying similar scenes.

arangel,

Which driver are you using with softquadro4?

arangel
06-14-2003, 01:39 PM
It´s not only a driver. The package consists of a bunch of files...

- Nvidia Detonator 42.51
- Softquadro scripts
- RivaTuner application

The instructions are at www.guru3d.com

You will have a performance boost, but keep in mind that the whole thing is a hack, and as such, a little buggy (I got a few artifacts when minimizing windows on the secondary monitor...)

With instances I was getting like 2.9fps, and with actual copies I get around 15.8fps and when I combined actual copies I get around 39fps

Nvidia Quadro 4 900XGL @ 1600x1200 32bit color
