SDL under Windows, and more....?

SDL Development
1

I’m using SDL under Linux, 'cause it’s great.
I use it under Windows too, cause I think it’s really easier than
DirectDraw.

Anyway, I want to use it with OpenGL, for commercial games and, while it
perfectly works under Linux, I noticed under Windows it is slower than using
directly WGL. Why? Does it depend by the way the windows is created or what?
I noticed the app is less fluid than the Linux version, which instead rund
at the same speed as the WGL Windows version. Why? I have a Matrox G400
graphic chipset.

Anyway, I’d like to know if SDL will ever be ported on X-BOX (I don’t want
to leard DirectGraphics…) and (this is easier, I suppose…) Indrema.

Thanx in advance.–

I’ll speculate that both of these will happen. The X-Box will most
likely support DX, and SDL is already ported to that. The Indrema people
seem to be interested in specifying their own API, but SDL is already a
popular Linux multimedia API, and it would make sense for Indrema to
support it.

However, being connected with neither Microsoft nor Indrema, I can’t say
for sure.

I generaly experienced problems while loading extensions with SDL under
windows while on linux works perfectly. I also got less FPS under win than
linux but I thought it might be a driver or compiler isue but it could be
SDL too… (I have a GeForce256 btw)On Sun, 28 Jan 2001, Marco Iannaccone wrote:

So it’s really seems it’s an SDL problem…–

Can you post a couple of side-by-side tests, one that uses SDL and one that
uses WGL for benchmarking and testing? I can test here on a Matrox G400.

Thanks!

For instance, the sources for NeHe Tutorials. The SDL version runs at the
same speed under Linux and Win32 WGL, while the SDL Win32 version runs
slower.
If you want, I can post some code, anyway.–

Anyway, what flags do you use when creating the Window? And what styles for
the Window Class?–
