Refresh rate vs fps

As i understand it the refresh rate is how fast the monitor is redrawing the screen. This sounds similear to fps in that fps are the number of frames that pass in a given time. From my understanding it appears that these two can offset each other, ie a high refresh rate and a low fps would be about the same visual quality as a a high fps and a low refresh rate. I'm trying to get a clearer picture of this and something seems fuzzy about my current understanding. Pardon the pun. What would be the difference in visual quality of a refresh rate of 60hz and one of say 120hz?

Personnaly, I think FPS and refresh rate is the same thing. If V-Sync is enabled and your monitor supports example, 60Hz in a given resolution, the framerate won't go higher than 60 FPS. FPS is a gaming term, while refresh rate is often used when describing monitors. 120 Hz will allow lot more smoother framerate than 60, and in Windows desktop on stable pictures, 60Hz is unsupportable to me, as you can see the screen flicker. This is my point of view though, as many other people (BladeRunner) could help you out on those subjects...

Yep - it is directly related to FPS. My monitor is at 85Hz and I get 85fps in CS even when the max fps is set to 100

Hey 600 dood, take off vertical sync on your monitor and your FPS will reach 100

Dukid - its a bad idea to take v-sync off with the geforce 2 mx. In games like CS you get tearing of the images. I think thats why 600R leaves it on. Hey - 85FPS is as smooth as it visibly can be anyway

60Hz refresh rate on a monitor gives me headache....

refresh rate and fps sounds similiar, but the main difference between them is that refresh rate is usually limited by the monitor, and once you've set it, it's constant at that rate; and FPS is all depends on the power of the graphic card and CPU, it varies from one sence in game to another.

If your monitor allows you to set refresh rate at at least 75 or 85Hz at whatever resolution you run your windows and games at(all recent monitors do), by all means do so. If you find yourself feeling sick after staring at the monitor after 5 mins, check the refresh rate : ]

Also, if you run games at different resolution and/or color depth than your desktop setting, you'll need to go to windows and set refresh rate on each and every resolution/color depth, otherwise the default or optimal setting is usually 60Hz... arrr.. my eye balls hurt


PS. V-Sync sets FPS to 1/2 of refresh rate. So, if the refresh rate is set at 60Hz (60 times per second) then FPS will be limited to 30 frame per second.

Fps is frames/sec, that sends your comp to monitor and refresh rate is how often your monitor shows those frames to you.
So if you have 2fps and 85 refreshrate, your monitor will show you 42 times samer picture and than 43 times other picture in 1 sec.
Refreshrate is important for your eyes and head, fps is important for you gameplay. They say, that you will not be able to realize difference between 24 fps and higher. But 60 refreshrate is minimum for your eyes....85 is just the right number...you will not be blind in your future...
That is my opinion.

Right on DanOertelt. The refresh rate tells you how many images the monitor is accepting from the videocard every second. The FPS in games and such tells you how fast your system is able to draw the frames for your program. I'm not sure, however, how Vsynch relates the two. Vertical Synchronization, hmmm...

jabroni - It only hampers your fps if you've got Vsync enabled. Vsync limits the video card fps to the monitor refresh rate setting. If your refresh rate is set at 100 Hz, and you're getting 175 fps in Q3, then you have Vsync disabled.

phenix - Yes the refresh rate is the number of times per second that the monitor is redrawing the entire screen. While it's good for your eyes to have the monitor refresh rate above 75 Hz, a high refresh rate will not compensate for low fps. No matter what your refresh rate is, if you're only getting 20 fps in Q3, it gonna be jerky and run like crap. So a high refresh rate cannot compensate for low fps as you seem to be thinking. But getting the refresh rate above 70 Hz will save you from headaches.

Another consideration is interlaced vs. non-interlaced. The 60 Hz refresh rate is interlaced, which means only half the scan lines on the screen (either odd or even) are redrawn in each scan cycle. This makes the flickering very pronounced. From 70 Hz on up, the scanning is non-interlaced, meaning the entire screen, both odd and even scan lines, are redrawn in every refresh cycle.
That's why the biggest difference is in going from 60 MHz interlaced to something like 75 Hz non-interlaced. Above that, most of the improvement is in the mind of the viewer. That is, unless Vsync is on. Because then the fps goes up with the refresh rate making the improvement more noticeable when gaming.

Dave B.i can appreciate ur knowledge but,i have it set to (on by default) which is set by default (v-synch)if i turn it to always off...i loose frames in timedemo..so it would seem ur statement is not all true..why do i get more with it on than set to off??
mind u this is point release 127 which sucks for speed compared to 117 which i was getting over 200frames per with v-synch enabled as well??
