Im relatively new to OpenGL programming, though not to programming in general. I recently started following through on the NeHe tutorials, using MSVS 6.0, under WinXP. I noticed that tutorials such as NeHe10, and infact almost all of them which have more than 2 triangles run incredibly slowly. When in full screen mode, I get far less than 5 fps on NeHe #10. My system is P4 1700mhz, Geforce mx/200 with 128mb RAM. Is it just me who experiences this? Out of curioisty I tried the same code on my Linux system and it ran at a ludicrously high FPS. What gives? Something to do with the PeekMessage() calls or the way OpenGL is used? Id love to know. Thanks, -loply

Hmm.
I noticed a few similar posts about apalling performance on WinXP, so I decided to have a bit fiddle.

The LOTR OpenGL screensaver runs at about 1fps.
Half-Life runs *FAR* slower than on Win98 on this machine (atleast 30fps slower).

I dont understand this, I have the latest nvidia drivers installed, correctly as far as I can see, the swap file isnt in use, and the processor/GPU should be more than capable of painting a damned cube!

Something is funky. Has MS broke OpenGL so that people will use DirectX and games wont get ported to Linux/MacOSX?

Anyhow, if its relevant my resolution is 1600x1200x32 and this is WinXP build 5.1.2600.

check the faq (at www.opengl.org)
try printf("%s", glGetString( GL_RENDERER ));
if u see microsoft then u have software == very very slow

Most likely your openGL ICD isn''t working correctly.

XP doesnt ship with a ''proper'' ICD, heck when I forgot to install the Nvidia ref drivers on XP I couldnt get HL to start.

Goto your gfx card maker and get proper driver install.

(insert here rant about M$ crippling competion, them being on the ARB and other such annoying rants)

I realy don''t see why pepole ask this question over and over.. Isn''t the first thing you do after installing OS also installing drivers?

There are more worlds than the one that you hold in your hand...

Yes, but M$ shipped winXP without proper OpenGL drivers.

Thanks for all the replies, wasnt expecting such a response

DarkWing: I had the latest drivers installed. Im not dumb

I did what a few people suggested and reinstalled drivers, after a bit more fiddling I realized (with the aid of some IRC`ers) that latest NVidia driver is the problem. Reinstalling an older (12.*) driver (instead of 20.*) fixed the problem.

exactly which ''latest'' driver did you try? Just out of interest

loply : I''m not talking graphic card drivers only. I''m talking stuff like via4in1 and stuff like that...
and about original drivers : thy are just a warper for DX..
