q about vsync

[lyssword]

If say my system runs cs:1.6 at 200fps I turn on vsync so its 85 fps now? will that also make less load on cpu?

Vsync prevents "tearing" of the screen. When you turn you might notice that the screen tears and will look like sections of the screen separate horizontally and don't move at the same rate. Vsync prevents this.

I don't know, I would where the CPU is involved in the rendering process, but AI Idk about AI.

vsync, to keep it simple, throws out the extra frames that your monitor doesn't show properly so that your frame rate remains the just the maximum your monitor supports. (In this case 85 FPS) Because you don't see those other frames anyway, you aren't losing anything and it's still going just as fast. The benefit is that vsync prevents "tearing", or distracting rips in the screen when you turn. vsync is a good idea for FPS games, because it helps your reflexes when turning quickly by keeping the screen clear.

That's a little sketchy. Here's how it works.

A Frame Buffer is an area in VRAM where the GPU writes a frame and holds it until the monitor is ready to receive it; when it refreshes. The GPU, by default, uses 2 Frame Buffers, alternating between one and the other. With V-Sync enabled, the GPU writes to both buffers, but never overwrites until a Frame Buffer is freed by sending it to the monitor when it refreshes. With V-Sync disabled, the default setting, the GPU writes to both buffers, not caring if it overwrites or not. The GPU can even send out a frame if it?s in the middle of overwriting it, causing artifacts known as tearing. Since the GPU cannot overwrite with V-Sync enabled, it has to wait, meaning it?s wasting power and writing less average frame rate. The GPU doesn?t wait with V-Sync disabled so it writes as fast as possible for optimal performance.

With V-Sync enabled, you will experience jumps in frame rates if your frame rate falls below your monitor?s refresh rate. Say your refresh rate is 60Hz; you will notice jumps from 60fps down to 30fps. A jump like this is very distracting. With V-Sync disabled, you will notice tearing, which is when part of the screen shows part of one frame and the other shows part of another frame. This effect is very easy to see in scenarios where there is flickering light in a game. This effect is more prominent on a LCD than on a CRT but it is noticeably decreased when the average frame rate falls below your monitor?s refresh rate.

Triple Buffering is an attempt to fix the jumps in frame rates that occur with V-Sync enabled by allocating a 3rd buffer in VRAM. It works well, except for a few details. Not all applications support Triple Buffering in Direct3D. Because Triple Buffering uses 50% more VRAM, you may have to lower your graphics settings in order to free up VRAM for Triple Buffering. It may also introduce mouse lag which may cause a negative gaming experience.

Whether you leave V-Sync enabled or disabled is based on personal preference about which disadvantage you can withstand more. I don?t mind the tearing with V-Sync disabled, especially if my average frame rate is below my monitor?s refresh rate, so I favor V-Sync disabled due to smoother frame rate.

To answer the original question: Yes, you will have slightly less load on the cpu, and even video, ram, and most other components that are used by the game.

Whered you get that info VIAN?

Are you gonna bust me for plagerism or something.?

It's from various readings and personal experiences.

I still have never seen tearing...or I've never noticed it....and I'm picky when it come to video quality....I'm guessing the fact that I use an LCD has nothing to do with it? (I really am bewildered as to what it looks like...)

thx for the replies

really? it looks something like this:
tearing
vsync

Thanks for the pics, go UT....but I've been playing UT recently (and I do move around quickly) so I think I would have seen that....but I never have...or I'm blind. I'll keep my eyes peeled.
