I'm developing a 2D game using MonoGame. I've got a square on the screen I can move around. The problem is that about once a second, the square jumps a bit. Using a frame counter I found here I've concluded that my FPS drops from 59.9988 to either 59.3988 or 59.6988. It's skipping frames.
I've tried googling and searching forums for hours but can't find a solution. I've commented out everything in the Draw method of the Game class except for the frame counter and it still happens. I even tried creating an entirely new MonoGame project with nothing in it except the frame counter and still I would get the frame skips.
Setting IsFixedTimeStep = true does not fix the issue. I do get higher frame rate, but also not as high as I would expect (not higher than ~100). I've looked at the diagnostic tools and there is no garbage collection going on (no yellow triangles).
I am completely at a loss. If anyone has any insights to offer, it would be much appreciated.
