Is glfwSwapInterval() reliable?

Question

Is glfwSwapInterval(1) reliable enough to cap framerate to 60 fps, or should I manually cap it myself? I often see people manually capping framerates instead of using this function.

Will the function provide a steadier, more stable fps than manual capping?

Answer 1

As far as I know, the glfwSwapInterval is to do with the v-sync on your monitor/graphics card. Have a look at this forum post which goes into more detail:

I'm not sure but on most modern hardware I expect it won't make much of a difference!
