Frame Rate Question
Okay, so I see people talking about getting frame rates of 80, 90, 100, even120 FPS on various games with various graphics cards.
My question is this: if you have your display set up for 60 Hertz, that means (if I am understanding it correctly) that the entire screen is updated 60 times a second. Im not sure if LCD screens have the equivalent of a "scanline" or "vertical retrace" than CRT monitors to, but they still seem to have this Hertz setting, so Im assuiing there is some periodic update time
So, If you have more than 60 frames per second, then arent some frames are "drawn" but NEVER SEEN on your screen, because the display itself can't update that fast?
So my question is this: What is the point of a FPS higher than the Hz setting of your display? Or is this Hertz value meaningless with LCD?

Re: Frame Rate Question
if your display is 60 hz then it doesnt matter after 60 fps. technically yes that does mean there are produced frames that never make it to the screen. That is where vsync is come into play. vsync caps your frame rate to the hz of your monitor which is probably used to save power for the card but people do not usually like their fps capped at 60 or the new 120 hz mark.

Re: Frame Rate Question
If you dont cap your frame rate to the synch rate, whats the point? Frame rate numbers higher than the synch rate would be pretty much imaginary then, right?
I.e. If your synch rate is 60 Htz, then there is absolutely no difference beween a FPS of 100 and 10,000,000,000,000. Its just imaginary numbers after that, the gpu claiming it drew a frame that never saw a pixel actually displayed.
(It would seem, anyway)
So why would people want to waste processing power to put up a number that doesnt actually mean anything? (It would just cause the gpu to be hotter, with no actual benefit.) I guess thats my question.

Re: Frame Rate Question
the problem with vsync in my own view was that since if never passed 60 that some times it dropped to a fps that i started to notice very little hints of "lagging" effect. but yes after it is basically wasted power. and who doesnt like a higher fps??? XD people do say that there is splicing if vsync is off but i have yet to notice that.

Re: Frame Rate Question
that's why I set max_fps at 60 :)

Re: Frame Rate Question
i keep mine at max_fps at 75 just for a little head room :D

Re: Frame Rate Question
I set mine to 60, but I get LOTS of tearing. I have also heard that vsync is horrible and causes flase interpolation, etc., so I'm not turning it on.
300+ FPS in CSS with all settings high FTW!

Re: Frame Rate Question
its only useful if you want to compare the power of two graphics cards. if you cap the framerate at 60, you won't be able to see any difference if they can both go higher.

See, this is the kind of thing I am talking about. Is 300 FPS better than 100 FPS?
No. They both appear exactly the same on the screen - only the guy with 300FPS is running a hotter GPU.
So why brag about it? Its like saying "My shirt has more invisible ultraviolet patterns than yours, although nobody can see them"
I dont get it. Is it just the thought that a higher number sounds better? Just a geek thing? My GPU runs hotter to produce imaginary images that no one can see?

to some people, yes basically. not me. id rather save some money on electricity :D
