OpenGL performance

[Mark Mossberg]

Has anyone noticed that the shaded performance of 9.1 is very sluggish

 

I have ver 8.1.1, and ver 9.1 installed on the same machine. Same exact settings and parameters on both. 9.1 is about 60% slower in all areas related to shaded display (rotations, pan zoom,etc.

I have not noticed. I'll give it a try though and report back.

Ok Mark,

 

I opened the most complex model I have. 366 Solids. Rotary Table, Grid Plate, Bushings, Threaded Inserts, 2 VIses (with all the pieces), Clamping Hardware, Washers, Capscrews, etc...

 

V9.0 SP1 = 11 Seconds

V9.1 = 11 Seconds

 

My system specs are as follows;

 

OS - WinNT 4.0

Service Pack - 6

CPU - AMD K7 - 1200

RAM- 512MB

Video Card- Matrox Millenium G450

 

Allocations

 

32,000

32,000

5,000

128,000

128,000

 

I've not noticed any system degredation at all. I've actually seen some improvements in speed between 9.0 SP1 and V9.1

Very, very, well said James..

he said between v8.1 and v9.1 ????

Ok, you caught me. Same file in V8.1.1 - 17 seconds of 35% LONGER for V8.1.1

 

In conclusion, I'm sssing the exact opposite you are.

 

SOrry I could not be of more help.

James,

 

Thanks for the reply,

 

The "only" area I'm experiencing performance problems is hardware aceelerated OpenGL, (shaded display). All other areas seem to be as fast or faster than 8.1.1, (especially solid verify).

 

All of my design work is done in Solidworks 2001+ or 2003. I use Parasoild for file transfer and prefer working with shaded solids

 

I use a Magellan Space Mouse to navigate around my models, and there is a noticable difference in graphics performance between the two versions. The same model will spin like a top in ver 8.1.1, and ratchet around in 9.1.

Don't know whether you'd notice with a Matrox G450. It doesn't really support hardware OpenGL. I think it may use direct X.

Although the Millenium G450 (or any of the Millenium cards for that matter) isn't a 3D workhorse, it does support both OpenGL and DirectX (http://www.matrox.com/mga/products/mill_g450/home.cfm).

To all,

 

First of all, I miss-spoke on this system config.. Im using NT40 SP6a, not Win2000.

 

If others using this O.S. are experiencing similar problems, here's the fix.

 

Delete opengl32.dll and glu32.dll from the Mastercam 9.1 root directory. These files drive OpenGL hardware accelleration. Mastercam sets itself up to use these by default. They aren't compatible with NT4.

 

When you delete them NT will use I'ts own components located in the system32 directory.

 

In my messing around, I've also uncovered a fairly serious problem with the uninstall of 9.1. I'll be posting a seperate thread about it. (if there's not already one out there)

 

Thanks guys
