Hi - I have recently bought a 22" Samsung screen and I am playing mostly at 1680 x 1050 - 60hertz (max) - I am notice alot of tearing in my games (Grid, Assasins Greed etc) now.

When turning on vsync the tearing seems to be less, but I have read that the vsync "on" equals the LCD refresh rate, in my case 60fps/hertz

I have tried Grid with vsync on and my max fps is 60, when I turn it off I get about 70 to 80fps.

Do you guys know of any other settings\tips I can use
and
Is playing with vsync on better even though fps will decrease:confused:

I am playing on a 8800GTX

Thanks

You are capped at 60fps because your monitor has a refresh rate of 60hertz. Increase your refresh rate to 75hertz and you will see your fps reach 75. Basically, you are capped to your monitor's refresh rate.
 
You want v-sync to be ON ideally....the whole purpose of v-sync *is* to reduce tearing. Leave refresh rate @ 60 on most LCDs. Some of them don't like higher refresh rates and you're not gaining anything anyway on the LCDs.

Forget fps...as long as the picture flows it doesn't matter. Anything above 29fps appears to flow to the human eye. Anything above will not yield any significant gains experience-wise unless you like bragging with fps numbers.

If you boost the refresh to inc the fps then your GFX is going to get hotter...without you gaining anything....rather boost the res.

Make sure your running @ the native res for the lcd.

I beg to differ. It depends on the game. A lot of games won't play well at less than 60fps - particularly extremely fast shooters. Try playing Call of Duty 4 multiplayer at 29fps. Blegh.

Anyway. If you can't see the tearing, then turn VSync off. Otherwise turn it on. I'm only bothered by tearing in certain games... Doom 3 engine and Unreal Engine 3 games of late.

Aside from the obvious frame cap at your monitor's refresh rate, VSync actually does deal a hard blow to actual performance. In other words, you may get 60fps without it, but you'll get less than 60fps with it on. Some games implement VSync more efficiently than others.

If you use VSync, make sure to turn on triple buffering in your graphics driver control panel.
 
I've seen the difference between 30FPS and 60FPS in a simulation game before, the difference is quite large. I should see if I still have it around here somewhere...

I know that there is a marked difference when playing any Source engine game at 30FPS and then at 60FPS. I stop noticing a difference above 72FPS.

Though the argument about how much FPS the human eye can see rages on :D

EDIT: I seem to remember that someone stated that if 60FPS cannot be achieved with V-Sync then it will work with a lower power thereof, such as 30FPS. Some interesting reading.

No def not multiples. If the gfx fails to produce a frame in time for the screen refresh, then the last frame will be displayed again. i.e. it just skips one update....which might then be used to the third update.

Vsync isn't handled by the game. Its implement from the DX/OpenGL layer onwards. When the game initiates the DX/OGL interface it specifies whether it wants vsync or not along with colour depth etc. Unless you're talking DOS era games...

i dunno man, fraps tsays bf 2 runs at over 100 FPS on a 22" running at 60

refresh rate has nothing to do with frames i think

also that 22 " samsung wont do more than 60 refresh rate
 
I heard that its better to run FPS with vsync on because what you're seeing is the most recently rendered image so it better for aiming, not sure how true it is though :)

The 100fps refers to the number of times the gaming loop completes a loop per second. The GFX will generate all 100/s, but will discard 40/s without displaying them.
 
How anybody can play with a line on the screen from texture tearing is beyond me :sick:

What's the use of fancy graphics when you got a line through the middle.

Most of the time you're looking at half of one frame and half of the next :o

What I mean is that different games tend to be affected differently, depending on whether it's on or off. I know the driver layer does it, but this implementation seems to affect performance in some games.

For example, turning on Vsync in Oblivion knocked it for six as far as performance was concerned... (On the cards that were current when it came out. You probably wouldn't see a difference now.)

Personally I don't notice tearing in most DX games, but YMMV. I can see it if I try to see it, but it doesn't actually bother me.

OpenGL games, otoh...
 
i have tried both and did not seem to make a difference

no tearing that you guys talking about

there must be something else wrong ... I have played all those games on my 22" and have not noticed any tearing whatsoever. runs smoothly.
