I''m working on a 3D terrain engine that renders a simple heightmap. I was playing around with OpenGL, trying to see what would be the best way of rendering the terrain so I wrote a little test program. However, in order to render a 10x10 tile map (with varying heights) I get a lousy 16 FPS! I''m running a P3 500 with an ATI 3D Rage Pro AGP 2x. I know that this isn''t the ideal 3D machine, but I know that Half-Life (and it''s various mods) runs nicely on this machine at 800x600 (probably low 20 FPS). What am I doing wrong? The tiles are rendered using GL_TRIANGLE_STRIP. The array of vertices is loaded into the vertex array. What''s wrong here? Here''s the link to my test program: http://chosendestiny.com/files/iso3d.exe

make sure your doin 16bit. also make sure you got he latest drivers. the rage pro is a MASSIVLY slow video card (and got only 4mb of ram). consider purchasing a voodoo2, you would be doing yourslef a huge favor. make sure you textures are not huge. that framrate you are getting does seem low, but then again the rage pro has terrible win9x opengl support. consider d3d where the rage pro drivers perform much better. though a voodoo2 in fullscreen mode will definatly be MUCH better. make sure vsync is off. half-life does not run well at all in opengl on a rage pro. you may have half-life set to use d3d, whihc is why its getting better performence (or even set to use software mode).

I tried it on my dual 1.2 athlon with a geforce 3...only 37 fps. You''re doing something wrong. Try to figure out exactly how many polygons you''re drawing per frame, maybe you''re doing some extra work you didn''t think you were doing.

I got FPS 90-110

Intel 733MHz
Win2K Advanced Server
512 RAM
S3/4MB

I would go with "Check your driver!"

No, that rate under WINE is not really unusual.


I meant it was weird after seeing the FPS that Sjelkjd posted . It seems like I''m not the only one without a low FPS though.
