From: Per Inge Mathisen Subject: [SDL] Fullscreen refresh on win32 Windows has a terrible default for fullscreen 3D apps of 60mhz refresh rate. This can be fixed by the user by going into his driver's control panel and forcing the refresh rate higher. However, this not a very user friendly way about it, and in any case SDL contains no code that could figure out this that condition has afflicted the user. So the question is, could SDL fix this for the user? It is possible under Windows to request a higher refresh rate. The danger is of course that if the user has an old monitor, and you request a too high refresh rate, the monitor could be damaged. However, I believe there might be a way around that: Check before switching what refresh rate the user's desktop runs in, and if our fullscreen dimensions are equal or less than those of the desktop, use the higher refresh rate of 60 and the desktop rate. Since most users run their desktops in the same or higher resolution something sane, this should fix this problem for most users. Thoughts? An alternative is to add an SDL_GL_GetAttribute(SDL_GL_REFRESH_RATE) option so that programs can bitch at their users at their own convenience. - Per
Simple DirectMedia Layer
(SDL)
Version 1.2

http://www.libsdl.org/
This is the Simple DirectMedia Layer, a general API that provides low
level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL,
and 2D framebuffer across multiple platforms.
SDL is written in C, but works with C++ natively, and has bindings to
several other languages, including Ada, C#, Eiffel, Java, Lua, ML,
Objective C, Perl, PHP, Pike, Python, and Ruby.
The current version supports Linux, Windows, BeOS, MacOS, MacOS X,
FreeBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX. The code contains
support for Windows CE, AmigaOS, Dreamcast, Atari, NetBSD, AIX, OSF/Tru64,
RISC OS, SymbianOS, and OS/2, but these are not officially supported.
This library is distributed under GNU LGPL version 2, which can be
found in the file "COPYING". This license allows you to use SDL
freely in commercial programs as long as you link with the dynamic
library.
The best way to learn how to use SDL is to check out the header files in
the "include" subdirectory and the programs in the "test" subdirectory.
The header files and test programs are well commented and always up to date.
More documentation is available in HTML format in "./docs/index.html"
The test programs in the "test" subdirectory are in the public domain.
