I have been unlocking the framerate in MonoGame via:
this.graphics.SynchronizeWithVerticalRetrace = false; base.IsFixedTimeStep = false;
And using it as a basis for how efficient I am updating and drawing in the game.
At a resolution of 240 x 160 with nothing being drawn or updated except a frame counter I get an FPS value of 9,000 to 11,000 FPS.
If I add all my code back in it drops down to about 1,100 FPS.
Is this a good indication that my code is significantly slowing the GPU down (10x), and should I be concerned? The game is going to run at 60 FPS so I'm still pretty far away from that, but at what point in the unlocked frame rate should I be concerned?
GPU: AMD FirePro W5000 (FireGL V)
