8800GT: direct3d or OpenGL??

[kamikaze]

Hi guys!

 

 

I recently purchased an 8800Gt 512mb graphics card and max 9 hangs(closes) using direct 3D(on files around 80mb up with alot of geometry) when in shaded viewport...wireframe is fine though. Smaller files don't have a problem.

 

When in Open GL ....max9 works fine during wireframe and shaded views.

 

Question:

 

1. Is there a problem with the software?(i tried 2 other cards, a 9600gt and another8800gt with same error results in direct 3D)

 

2. What should i use in practice -direct3D or openGL?( i mean what would best optimize my videocard)what would be better?

 

*i noticed rendering time on openGL and direct3D are only seconds apart with direct 3D being a bit quicker.

 

Please let me know coz im not quite sure which is better

 

thanks!!

 

 

PS. my hardware:q9300 C2Q

intel P35 board

2gb dual channel Corsair

8800GT 512mb GPU

500GB HDD SATA

I have an nVidia 8800GT with 1 gig of ram, and I use Direct3D 9.0

 

After I got the card installed, I downloaded the latest video drivers from nVidia and can run it in any mode. As I recall, I was told the Direct3D mode is 'the best'.

 

The video card does not affect the rendering time.

Caveat: your video card mode has no effect at all and I do mean none on your render time. And OpenGL is a robust system but not by any means the fastest way to utilize a Geforce card.

 

Also, 80MB is a large file. A lot of systems can't handle that, which is why a lot of us are switching to 64-bit systems.

 

Now, some things to try:

 

-Set some of your more complicated objects to display as box. Most of the time you don't need to work on most of your objects at once.

-Related trick: put some of your more complex stuff in a separate file, Xref it, turn it off and bring it back only when you need it.

 

Tricks like that seem to be out of style, with computers being as fast as they are now, but they still can be useful.

 

If you don't want to do that... well, I'm looking for somebody to be a guinea pig for testing an 8800GT to Quadro 3700 softmod hack. It's what's discussed starting at the third post on this page. In the instructions given in the link, your original PCI ID should be 0600 or 0611 and your new ID would be 061A, and make sure to run Cinebench's OpenGL test from cinebench.com before and after to see if you get a bump. In theory, using the hack would increase your OpenGL speed in Max by a substantial amount.

Thanks for your replies!

 

yes direct 3D is better as i know it. So who utilizes open GL??

 

Thanks for shedding light on the" videocard does not affect rendertime".......

 

AJLynn you're right, I believe ill be setting xrefs on my building scene as it has become quite heavy.

There is a deal on some 8800gts 320mb g80 cards for $88 and I may get one and try the soft-mod....I am willing to crap out a $88 card but mot my $350 gfx card.

 

 

edit: now the card is $99.99 plus $8 to ship---heres the link http://fxvideocards.com/ZOTAC-GeForce-8800-GTS-320MB-ZT-88SE320-FSP-GDDR3-PCI-Express-x16-SLI-ZOTAC-Video-Card-p-16285.html
