How to get the screen refresh rate?
提问by Newbie
Is this even possible? Since ive noticed v-sync doesnt work on my laptop at all, so i am building FPS limiter "manually" and now i would like to use the FPS limit the user has set to his screen.
这甚至可能吗？因为我注意到 v-sync 在我的笔记本电脑上根本不起作用，所以我正在“手动”构建 FPS 限制器，现在我想使用用户设置到他的屏幕的 FPS 限制。
Edit:i mean the monitor hz rate.
编辑：我的意思是显示器的赫兹率。
Edit3:heres the code i got working (i think... anything wrong there?):
Edit3：这是我开始工作的代码（我认为......那里有什么问题吗？）：
DEVMODE lpDevMode;
memset(&lpDevMode, 0, sizeof(DEVMODE));
lpDevMode.dmSize = sizeof(DEVMODE);
lpDevMode.dmDriverExtra = 0;
if(EnumDisplaySettings(NULL, ENUM_CURRENT_SETTINGS, &lpDevMode) == 0){
framerate_limit = 60; // default value if cannot retrieve from user settings.
}
On demand, here is my v-sync enabling code jay.lee asked for:
根据需要，这是 jay.lee 要求的我的垂直同步启用代码：
PFNWGLSWAPINTERVALEXTPROC wglSwapIntervalEXT = NULL; // global
...
wglSwapIntervalEXT = (PFNWGLSWAPINTERVALEXTPROC) wglGetProcAddress("wglSwapIntervalEXT");
v_sync_enabled = 0;
if(wglSwapIntervalEXT != NULL){
if(wglSwapIntervalEXT(1) != FALSE){
v_sync_enabled = 1;
}
}

The Win32 EnumDisplaySettingsfunctioncould be what you're looking for. The refresh rate is held in lpDevMode->dmDisplayFrequency.
Win32EnumDisplaySettings函数可能正是您要找的。刷新率保持在lpDevMode->dmDisplayFrequency.
