What is vsync?

[tiger3]

What does it do? Why is it important?

Vsync ON makes any game to draw the screen once per vertical scan of the monitor. So, if you have the vertical refresh rate set to 75Hz, you will not have more than 75 frames per second. Vsync ON waits untill the scan line is at the botton and then allows the drawing operation.

VSync OFF makes your graphics to be drawn unsynchronized with the vertical scan, you can see graphic glitches (parts of graphics that are shown before ending the drawings). This way you will get maximum frames per second at the cost of graphic distortion.

There is an urban legend without any technical base about suffering rubber bullets with VSync OFF. VSync does not affect any calculation of polys hitting polys, in fact, you would get faster results with VSync off.

where do i set it on\off?

I guess all the times Skuzzy has said that you lose frames w/ vsync off, during which some of our bullets could/would be dropped, BUT I would tend to call it fact as opposed to urban lgend.

I suppose only pure maths are involved into bullets hitting a target, being it drawn or not. I suppose that reindering images sync or unsync will not interfere with the hit calculations.

V-sync off doesn't effect weather or not a hit is a hit it just messes up your aim because the other plane is not always where you see it. The big myth is that it will increse your FPS, it will only increse your highest FPS where you don't need it anyway, it will NOT increse your lowest FPS at all.

zmeg is right,

if your curent max fps is 60 and your moitor refresh is 75 dont take einstein to work out vsink aint slowing ya down.

go to your video card, then click performance and quality.. But Do not turn off VSYNC. HTC has tested this it does cause Rubber bullets...........




to find video card

1. Right click on startup screen
2. click on properties
3. then advance video controls

[Flyboy]

checked all the tabs under the advance, i do not have that option
i have a MSI radeon9800P

i dont have rubber bullets, atleast i think i dont have.

what i do have is sometimes when i hit the enemy plane there are No hit sprites (i know i hit it because i see parts falling from him)

is that normal?

 sorry a radeon card holder will have to tell you where vsync is. If you don't know its loc don't worry default is program comtroled meaning on

[rod367th]

oh and by the way some will say they have vsync off and get 300 fps, doesn't matter since no monitor has that high of refresh rate ,  Even tho some in game will swear they have 1.........any one that brags about fps is usally full of chit. after 40 fps hard for human /Eye to tell dif. you get 40 or more steady don't worry aout anything

[la7'sRule]

old 8 bit systems used 35 fps so do web cams... 35 fps is what the human eye needs for a seemless picture,

16 bit systems also used 35 fps.. Only when the play station 1 came out did we beginn to hear about these ludicrous fps...

60 fps Was Maximum for A long time for games like Motor head This game Was Incredibly fast flowing...
But aces high realy dont need that much fps... I limit mine to 60fps. Which is more than enough.

40 fps and u may miss a few gfx But realy It dont afect the game play.

and even as low as 35 fps and the game is still perfectly play able.

try to increase your frame rate by...
up dating video drivers.
closing other programs
make game load gfx in to system memory (if you have ebough ram)
Limit your display to 800x600 (espeshialy for the geforce serize)
change in game gfx settings to higher preformance,
disableing tracers will help fps when you shoot.
Change floor draw distance to a low setting.
make your fog visibilaty to like 7k
turn off terain mipmaping.

now all that should get you some high fps.
If im worng Please feel free to yell at me a while

by the way i do have a v sink option on my gfx card....
also I am able to manualy state each individual fps setting  for any individual game i may play,

i gain acces too v sink by....
going to display properties>advanced> "geforce tab This will differ">preformance and qualaty setings
"this could be called anything from preformance to 3d setings"
then i disable Aplication controlls v sink, and i can finaly turn it off

Also...

i have been visiting other forums looking for a answer to your question (how do i turn off v-sink)

Closest thing i could find to a answer : Control Panel > Display > Settings > Advanced > 3D >
 
and aparantly the gfx card you use Does preform poorly with v sink enabled,

here look at these bench marks from doom 3
--------------------
1600x1200
High Quality(0AA+8AF)
All graphic options on
Vsync ON
40.0fps avg
------------------------
1600x1200
High Quality(0AA+8AF)
All graphic options on
Vsync OFF
56.5fps avg
----------------------------------------------------------------------------



10x7 High Quality 0AA:
vsync On: 49.1 fps
vsync Off: 72.2 fps!!!!

With 8X AA on:
vsync off: 19.3 fps
vsync on: 16.5fps

With 2x AA on:
vsync off: 63.5fps
vsync on: 40.9fps


12x10 2AA:
vsync Off: 48.5

If you feel people in this forum can answer your question better (i think all of them use your gfx card) Then here is the link
