Re: [Interest] R: Qt3D FPS limits

Using vsync as a frame rate limiter is not a good idea, because of different refresh rates between monitors. On a 144Hz monitor, you'd be running at 144FPS even if that's not actually wanted. Or, you might want to run at half the refresh rate (like 30FPS on a 60Hz monitor.) Vsync and frame l

Qt3D relies on your GPU vsync settings. To reach the maximum number of FPS, just disable vsync in your driver settings. If on the other hand you want to reduce FPS, call setSwapInterval on the QSurfaceFormat::defaultFormat and set it before starting your Qt3D application with QSurfaceFormat::setDef

If you want to lower the limit you can simply add a pause in the rendering thread before the swap buffer based on a timer. I don't really know how to do that with qt3d, but with qt quick there is some slot like onBeforeRendering and onAfterRendering in which you should be able to insert a FPS limit
