"While enabling vsync does fix tearing, it also sets the internal framerate of the game to, at most, the refresh rate of the monitor (typically 60Hz for most LCD panels). This can hurt performance even if the game doesn't run at 60 frames per second as there will still be artificial delays added to effect synchronization. Performance can be cut nearly in half cases where every frame takes just a little longer than 16.67 ms (1/60th of a second). In such a case, frame rate would drop to 30 FPS despite the fact that the game should run at just under 60 FPS. "
I was reading the triple buffering article under video and I had a few questions from the above passage that I was hoping someone could clarify:
1) What does "internal framerate of the game" mean?
2) When we talk about FPS, are we referring to the actual number of frames being displayed on the LCD Panel per second or are we talking about the actual number of frames being rendered per second by the GPU, these rendered frames not being pushed to the frame buffer?
3) Where/How does 3D Mark measure the FPS?
4) When a panel is 1920 X 1200 @ 60 Hz, is there any possibility of the panel displaying more than 60 frames a second? If no, how does it matter if the GPU can render anything more than 60 frames a second?
5) I didn't understand the last 2 sentences of this passage. Could anyone explains this better?
Really appreciate any helpful response. Thanks.
