Have to say from what I've seen is that OGL stuff is generally 10-20% faster than Dx for comparable output in today's games...

To be objective, OGL and DX performance are identical. Performance depends on coding efficiency and not the API used.

Hmm well, in IL2 Sturmovik (my main testbed) it is generally 10-20% faster when switching from using Dx to OGL...no code difference there..?

[davepermen]

speed of gl against dx depends largely on drivers. the interfaces are, while syntactically different, technically about the same.
the speed in the end is nearly always the gpu. and there, dx and gl use the same paths..

aphex: by definition your DX code and your OGL code are different. You may have written your OGL code better than your DX code. Someone else might do the opposite and think that DX is better.

emm, I don't think OpenGL Performance is slow,some time I using OpenGL finish game project will faster then direct x. But is OpenGL + window programing. :huh:

[davepermen]

hm.. windows programming suxx in general, and yes, gl bindings to windows are crap.. one thing that should be rewisited in the gl2 specs, as far as i know (something in the form of glCreateContext, and then just wglBindContextToWindow(HWND hwnd) )

but i'm not sure..

when gl performance is slow, its wrong setup for pixelformats and that, wich forces at least parts of the driver to go software mode..

[baldurk]

unfortunately that would require coding on microsofts side. I doubt they're going to do that.

[davepermen]

it just means to wrap up the code bether.. no need to be on m$ side..and driver developers get nearly full access anyways..

Guys , I didnt know where to post this problem...But can someone tell me how to uninstall NetMeeting? Its fucking my GC...This was the cause of my problem , and now I dunno how to uninstall it.

[davepermen]

normally, netmeeting is not to uninstall. and normally, it should not cause your problems (as it is possibly installed, yes, but normally never runs, no..)

to uninstall it, you have to check some of the fancy pc magacines (or their web-equivalents). a longer time ago, i've read in one or two of them, how to get windows to show up own software in the software dialog, available to uninstall..

Strange that NetMeeting would be a problem.

I ran it last Friday, and went through the setup dialogs, and at the end of it all it informed me that all NetMeeting functionality has been replaced by MSN Messenger services. Thus NetMeeting is no more.

Well , I discovered the problem , I had on my computer a software that used in a way NetMeeting...The combination between the two fucked up my GC...Now , after I uninstalled that software , everything is OK :D

[davepermen]

great

nice avatar btw
