120 fps on a 60 hz monitor?

post #1 of 9
Thread Starter 
Was playing the first witcher an noticed my fps going well above what my refresh rate is and noticed no screen tearing, what gives. I don't want screen tearing but I notice it in some games more than others. Why is this?

Maybe some games have vsync enabled or you dont get as high fps ?

A tear occurs when there is a switch from one image to another that is noticeably different in mid screen. The higher the framerate, the less things change on each screen, so the smaller the tear will be. For example, at 120 FPS you will get four small tears rather than the one big visible tear that you would get at 30 FPS. Also, the speed of the game and how fast things change in game impact the perception of tearing with slower games exhibiting less tearing due the the screen looking very similar frame to frame while the fastest games have quickly moving objects that you are more likely to see "cut" above and below the tear.

i do not turn on Vsync in any of my FPS games. maybe racing games yes, but not FPS. because the higher the FPS the smoother / quicker your game will be displayed on your screen (honestly that also involves your screen's refresh rate / latency)

It is always ideal if you can lock your FPS at two times your refresh rate.

Much smoother.

that is true when i had a 5ms 60hz monitor. but once I upgraded to the VG248QE keeping up with 144 FPS while game is also a challenge in new games, but that doesnt matter much.. specially when this monitor has 1ms latency, all games are extremely smooth

so you might wanna always keep in mind the latency

I've noticed the same thing. Even though I have a 60hz monitor, things are much smoother when I'm running over 90FPS. I have no idea why this is so... but its a noticeable difference if the frames drop down to the 50/60 range.

I get zero screen tearing too. I have a very nice GTX670 that is silicon lottery material for sure. Maybe that helps.

Yeah, both my 670s do just under 1300 on core easily

Actually it is the opposite. Frames are meant to be shown in sequence. If your monitor can't refresh fast enough to display all the frames it is better to have a lower fps rate. If it skipped from frame 1 to 4...you might not notice it because there isn't a lot of difference between frames 1 and 4. However, if it jumped from frame 1 to frame 10...you will probably see a large tear since there will probably be quite a bit of difference between frame 1 and 10. Think of it like one of those pads of pictures that if you flip through and it looks like it is moving or even a movie film. If they chopped out a lot of the pictures or removed a chunk of film...you'd see weird stuff displayed. And when you are actually playing the game you will be skipping from 1 to 10 to 19 to 28...ect...thus you get tearing. This cumulative effect is what we see. If you missed 10 frames one time you probably wouldn't see it at 60fps or if you did it would just be something you took in stride and kept playing.

I personally don't seem to notice tearing until about 80 fps...I know it happens from 60 to 79 fps on my crudy old monitor, but I just don't see it. However, when I do see it...it really bothers me. So I typically have adaptive Vsync turned on.
