Hello,

I'm creating a little game, and well I've been using Direct3DRM. Ok, I know a lot of you are gonna say, switch to OpenGL or IM, but this is my final project necessary for my satisfied understanding of Direct3DRM.

I was just curious, what the maximum number of polygons (triangles) I should render per frame. I'm running a P3 450, but I want this program to run on a 233 at least. How many polygons should I render per frame or second to achieve a playable fps of at least 15.

It's a fighting game if anyone cares to know, any help and interesting info concerning Fighting games would be appreciated, but what I'm really trying to find out is the answer to the polygons per second question.

I really appreciate your help,

P.S. I'm using my own Animation engine, deforming a mesh using my own animation functions.

Hi !

1) The most important thing for getting the engine running fast is the 3d-accelerator, so you gotta decide if you want to create this engine for 1st, 2nd or 3rd generation hardware accelerators.

2) I own an Elsa Victory Erazor (Riva 128, 4 MB) and my engine works pretty fast on a 233 mmx. I use Direct3D Immediate Mode, but it renders about 4000 Polygons per frame with a relatively high frame-rate (with 17 different textures). So in RM, you can easily use up to 2000 polys per frame.

3) Create your engine that it'll work with older cards, too, for example drop down the screen resolution or bit-depth to make it running faster. I've got problems with page-flipping with my card, I dunno why, so I checked the caps before and then decided between using page-flipping or blitting.

Thanks for the help.

Actually I am writing this so a user running a relatively old computer which is not so old (ala P2 233).

How many polys per frame could I pop out while having a good frame rate on a non 3D-accelerated 233 for example.

Non-accelerated ? It'll be really slow in any resolution but ModeX, even if you use only a few hundred polys. But nearly everyone owns a 3d-accelerator today, so you shouldn't build your 3d-engine for those people who do not own such a card.
