I saw a similar problem to this one listed a few days ago, my program is running realy slowly. I read a page on optimizeing opengl code, it talked about droping unnesisery buffery things, and removing slower options such as dithering. I did all these things, and I still get about 5 frames a second with 108 polygons on screen. I have all the polygons facing me so backface culling would not help. When I turn off backbuffering I get a 100% speed boost but thats still not enough (only getting 10fps). Commercial games run at a normal speed on my system so I know thats not the problem. I don''t know if listing my full source in this forum would be apropreit if you think you might be able to help more easly please say so in your replys. Thanks, Klaus

It''d be important for us to know your video card and computer specs.

Presumably you are running in software mode. I say presumably, because It''s slow even for software.

Check your pixel format - make sure you are selecting a format that can be accelerated in hardware: something like 32 bit colour, 24 z, 8 stencil etc.

Regards

BTW - post your specs nect time!

sorry about the specs, here they are:
msi k7t turbo, and an nvidea(sp) tnt2 model 64.

no offence but thats messy code =)
ok, from what i can see (i'll look harder after dinner)
- ur calling glVertex3f() while using integers
int->float is on of the the slowest type conversions there is,
also the constants aren't being compiled using the .f thingo
eg. usr using glVertex3f(100,100,0); it SHOULD be glVertex3f(100.f,100.f,0.f) or glVertex3i(...)

ESPECIALY for glTexCoord2f man!

- if ur using VC, pres Ctrl+H and replace glVertex3f with glVertex3i.

- use display lists dude !!!

k, im off to eat, i'll look harder when i get back, Cya, hope that helps

Have you checked out NeHe s stuff. Do his tutorials run faster on your system?

Try a 16-bits color mode with a 16-bits ZBuffer. Make sure you''re not running in software (use glGetString(GL_RENDERER); if you see Microsoft Generic, you''re in software).

Thanks for all your replys.

I was originaly running in 16/16 mode so Idon''t think thats my problem.

Silvermace, I cut out the code that was using the ints and it still runs realy slowly, I got couple more frames a second but it was not that muck better.

How do I use glGetString(GL_RENDERER)? What kind of variable do I shove it in to?

char *filename = glGetString(GL_RENDERER);
//and print out

logFile.Write("%s", filename);

Something along those lines

sorry, I tryed all day and was not able to figure out the pixel descripter thingy. I assume that you were talking about PIXELFORMATDESCRIPTOR::dwFlags but I am unsure of the correct sintax (I''m a real newbie).

What are your textures sizes ? Since you don''t seem to use mipmaping, using big textures when drawing little polys may mess up your video card cache and give you poor performance.

tiles[8/*mapxy*/].polys[index].vers[0].x
doesnt this kinda run slow? Btw add some // tags in front of the render scene, to check if thats the prob or not.

I droped all my texture sizes to 32X32, and now I get about 17fps

, still not good.

I get about 20fps minus my scene.

Try using timeGetTime or QueryPerformanceCounter instead of clock. And your code is a pain to look at.

Every call to glBindTextrue() is a big performance hit. You have about 10 textures going there and oyu change them for every poly. This can cause your video card to dump the texture cash and reload everything. Try to load each texture once and call all the polys that use it before switching to the next one.

You use GL_POLYGON and GL_QUADS a lot. They are the slowest primatives to use. Try to use GL_TRIANGLE or GL_TRIANGLE_STRIP if you can.

Build all your primatives using display lists. They are precomputed and display much much faster than drawing your polys manually every loop. You can also bind your texture when you build your list if you know that it is not going to change while the program is running.

I think you''ll find it''s maybe your FPS counter that''s completely wrong - don''t use clock(), (use GetTickCount() or similar)

Also, don''t use TextOut to display the frame rate. an easy way (for your purposes) is not to run in fullscreen mode, and use SetWindowText to display FPS in the title bar - it''ll at least verify what the actual frame rate is.
