FPS Questions
Posted: Wed Feb 10, 2016 2:29 am
This is just something I've never thought about before. If I have a 60Hz monitor, I assume it can't display more than 60FPS no matter how strong my hardware is. First, is that correct? So if the FPS counter says I'm at 260FPS, is the hardware generating these screen frames and then just throwing them out, or is the monitor just ignoring all the extra ones, or wtf is happening?
If the graphics card can't maintain 60FPS - say it drops to 50FPS on the counter, and v-sync is on to avoid tearing (I'm talking out my ass a little bit here), does the monitor just repeat the previous frame if a new complete one is not available? And does that mean you are actually getting 30FPS, at least for those 2 cycles? And then does it bounce between either 60FPS and 30FPS for an average of 50FPS? Or can the monitor reset when it starts displaying a frame, so instead of displaying a single frame for 2 cycles, it displays a frame for 1 cycle, and then nothing for 1/2 cycle, and then start again with a second frame?
Why I ask.
I was getting annoyed by the map taking 10-20 seconds to open (dear FD, but they don't care). I thought I'd try the trick of disabling the frame rate limit. Then I was only getting about 130FPS, which seemed low, and I discovered my SLI was disabled again! I assume this happened with the latest game upgrade. After I fixed that I was getting 260FPS (out in deep space exploring). The map did open quicker, but then I started wondering about what was really happening.
