Got it. Yeah there should be a method to return resolutions for the device. I’m just helping him with the Mac stuff but it’s his project so not sure if this on the list (the API is meant to be small as I understand it). SDL has a pretty comprehensive list of device functions so that leads me to believe its important. > > 3: > I’m not sure if he wants this to be part of the API. I use SDL and I’ve just used Load_GL_VERSION_XXX calls that the FPC RTL provides which works. Just looked and I see SDL has some functions that you describe. I think the FPC RTL is cross platform also though so this may not be needed for us. function SDL_GL_LoadLibrary(path: SDL_Char): LongInt; cdecl; external; function SDL_GL_GetProcAddress(proc: SDL_Char): Pointer; cdecl; external; procedure SDL_GL_UnloadLibrary; cdecl; external; > > 4: > > In your source code for Windows you are using GetTickCount to return the > time.

NSDate is millisecond precision I think.
