Date: Sun, 6 Mar 2005 17:06:20 +0100 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

>The SDL library is designed to make it easy to write games that run on Linux, *BSD, MacOS, Win32 and BeOS using the various native high-performance media interfaces, (for video, audio, etc) and presenting a single source-code level API to your application. SDL is a fairly low level API, but using it, completely portable applications can be written with a great deal of flexibility.</P
