OK this dumb ass needs some 'splaing. Stuffzz was talking the other night about the new 120hz monitors and how they might help in gaming,,,so I thought I would look into them and see what they could offer me as I need all the help I can get.
What I understand is the human eye/brain (comprehends) sees 30 frames per sec. Most monitors are 60hz with some able to be 75hz. So here is one question. If you have a 60 Hz monitor but your video card is producing greater than 60 FPS, say 100 fps, is the GPU just wasting the extra frames since the monitor only refreshes @ 60 Hz?
Some monitors now have the 120Hz now for a higher price and also 3D. Most of these 120 Hz monitors are not "true" 120. From what I read the monitor uses interpolation or inserting copies of frames. If my eye/brain comprehends 30 fps what am I gonna do with the extra 90 frames? |

Youre right about any frames rendered above 60 fps on a 60hz monitor are lost, but if you uncap your frame rate and/or don't enable vsync, your video card rendering more than 60 fps will at least ensure that your vid card isn't working so hard.
You may not be sensitive, like some people are, to the 60hz fluorescent flicker effect. Your brain may not be able to process above 30 frames, but the 120hz monitors are built for gamers coz there is less mouse input lag - the windows on screen and game action will render without the tears or lag found in the 60hz monitor. Tearing being mis-alignment of the screen content, if you look closely at your screen's images while in game, you will notice a lack of sharpness on moving / standing targets ... or a fuzziness that comes from the image being out of alignment.
The model he's demo-ing is currently the best out there in a 24" monitor. If I were to buy today, it'd be this model - like its stand, especially. |

Think of it this way Papa.
Let's say it takes you 60 frames to turn 180 degrees (it won't but it makes the numbers easier). So you have 60 slices or vertical lines to your aim. Now the enemy is 90 degrees to your right so that is 30 slices. Between 29 and 31 slices should be your aim on the target. What if that slice doesn't line up?
Now let's say you have 120 frames. So now you have twice as many slices. So if slice 29 and 31 didn't line up now you have two more slices between those (60 and 61 between 59 and 62). So your aim gets a little bit more precise.
Now imagine your framerates are jumping around. You are looking one way and have 120 fps. You turn to shoot the enemy and your frames drop to 60 or 80. That smoothness from the extra slices gets lost and you are moving you mouse to aim based on that many slices, but then over aim cuz the slices are less when the framerate drops. The same in reverse if you are at 60 fps and you go to aim and the frames increase. Then your aim falls short.
This is why VSync is nice. You are locking the framerate to the refresh rate of your monitor. 60Hz will give you 60 fps and no change. You aim and it is consistant. Then you can base your mouse DPI and speed and have that be constant as well. 120Hz will give 120 fps and a smoother aim with more precision than 60Hz.
And you will notice the difference in FPS on a 60 Hz monitor over 60 FPS. Go check out your old copy of Spearhead. Do a com_maxfps command in the console for 60 fps and then up it to 120, 180, and 240 fps. You will definitely notice a more smoother movement as you run around and turn. Lots or articles claim over 60 fps is a waste, but many gamers say that isn't so. |
