VSYNC OFF/ON?... what the hell is Vsync anyway?

[DougFrippon]

Well.. I was capped @60fps in half-life counter-strike... then set Vsync OFF .... no difference... exept that I now do 100fps...

What the hell is that option?

turn vsynch off in opengl. gives you a good boost to framerate. forgot exactly what it does, something with timing the monitor and the vidcard (?). settings/control panel/display/settings/advanced/vid card tab/additional properties/opengl/vsync always off. for your frame rate cap in half life, type "fps_max 100" in the console. no quotes.

VSync synchronizes a game?s maximum 3D rendering frame-rate to the vertical refresh rate of the monitor. With a 60Hz vertical refresh rate, for example, a game with V Sync enabled would not be able to render frames faster than 60 FPS, which can result in pauses or lags in the action as the rendering is delayed to synchronize it with the next screen refresh.

Disable VSync to allow the video card to render frames as fast as it can, then it will be able to exceed the monitors vertical refresh rate.

Note: While disabling Vsync can allow for higher frame rates if your system is capable of it, it can also allow for some screen tearing or artifacts under certain albeit rare conditions.

Thx for that precise answer Rand, that's what I wanted to know

In CS the tearing is quite obvious. And (also in CS) I do not "lag in the action". I run it at 85 Hz V-Sync on, and it looks liquid smooth. V-sync off and the tearing is very very annoying.

In Tribes2, however, I can't run with V-sync off because it drops my framerates by 20 (!!). This may be a better example of the lag-while-processing. But in CS, leave V-sync on if your system can handle it! DougFrippon, it just sounds like you need to run your monitor at a higher refresh so you can get higher FPS with v-synch on.

Glad I could help.
I generally leave Vsync disabled for all my games as it rarely causes any issues of screen tearing or artifcats with modern video cards.
