Is it possible to disable frame-limiting in libGDX?

Question

More specifically, a desktop libGDX-LWJGL application. There are configurations options to disable CPU syncing as well as vsynching, but regardless the application runs at 60fps

Answer 1

The answer depends very much on the speed of your CPU and graphics card, but if you try a configuration like the following when you create your application, and disable vsync on your graphics card, then that should push it pretty hard.

LwjglApplicationConfiguration cfg = new LwjglApplicationConfiguration();
cfg.title = "Framerate test";
cfg.width = 1280;
cfg.height = 720;
cfg.fullscreen = false;  
cfg.useGL20 = false;
cfg.useCPUSynch = false;
cfg.forceExit = true;  
cfg.vSyncEnabled = false;

Disabling vsync will be somewhere in the settings for your graphics card. On my nVidia card, it is given as "Vertical sync" in the options. It was set to "Adaptive", capping the frame rate at 60fps, but after setting it to "Off", I saw > 4000fps as measured by fraps.
