What does that do? I had it both checked and unchecked, and i realy dont seem to see any difference.. It's in the Video options, under "full screen" i believe

It's a V&W desroyer, in the Scapa Flow harbour. It was really annoying, so i just had to place a torpedo in the middle of it http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif. The pic is called "dive-by"... like fly-by...

Synchronization does something along the lines of matching the game's display to your monitor's refresh rate. If your game plays fine with this option unchecked, leave it that way. Only a small number of players might need to use this option.

Some real-time games use a clock timing mechanism, which can be the V-Sync of your screen refresh rate or the PC's Real-time-clock (RTC). This sometimes produces jerkiness in the screen updates when the video data rate cannot keep up with the Sync times.
If you don't see any difference, it means you have a powerful/fast enough PC to handle the games Video Data rates = No Problem

I thought it was kind of the opposite???
If your PC puts out more FPS than your refresh rate can handle you will get jerkiness and tearing? That's what I read last night, maybe it was wrong but....
I just got my new set up running the other night and I had a weird blurry horizontal line that would shoot up or down the screen when I was on the bridge looking around.
I'm getting 110 to 120 FPS with 4X antialiasing and 16X anisotropic.
I checked the sync option and it locks me at 60 FPS with completely smooth animations.

Nice http://forums.ubi.com/groupee_common/emoticons/icon_cool.gif. What processor and graphics card do you have to get that kind of a performance? (I'm looking at my options for upgrading soon)

Sorry there, Forgot to mention that the sync also co-ordinates the video/display ram updates. Usually sync'ing only allows updating during video 'blanking' periods (the part of the video you don't see). Whereas going the other way you get streaking when your display (vram) picture is being updated while it's being outputed to your monitor.

This all depends on your graphics card configuration.
Dual-ported Vram, Double/Tri buffering, Bi/Trilinear buffering, elliminates these wobblies.

So you might find you have to tweak you GCard settings. It's a while since I've dabbled with this, so might need a little updating!

Another point to consider is all this hype about FPS.
A game might tell you that it has 120 FPS, but if your monitor is sitting at 60hz refresh rate (FPS) it makes no difference - You are only getting 60 FPS. Another problem here is that if the FPS is not an exact integer multiple (1,2,3,4...) of the monitor refresh rate, you will get wobblies like blurring and streakies, or picture speed variations. This not being so pronounced as below, but noticable.

You must only worry when your game tells you that the FPS is less than the monitor refresh rate - this is when you get screen stutters, pronounced streaking etc.

So the best setup is to go 'synchronised' for smooth animations.

Well this I can understand http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif The other tech stuff slightly went over my head, but I get the jist of it.
I'm not sure what tweaking I can do with the video cards though, but do I really need to? Checking the sync option seemed to cure all my graphical anomolies (sp?) Which so far I have only experienced with SHIII.

@vikinggrandad............ This is probably my last build for a very long time, so I went all out. Spared no expense.
I'm running an X24800+ and dual 7800GTX's. So far it's coming along fairly OK.
If you read the sound card thread here, I seem to be having trouble with my X-FI fatal1ty and SHIII.
I can't get Battlefield 1942 to play at all, with the X-fi or onboard sound.
I got to test out Halo and Half Life 2 today using the onboard sound and they played great.
I have a lot of other games to get installed and test out and probably work some bugs out, then I can determine if this set up is worth it or not.
I'm more interested in newer games playing flawlessly on this system, so I need to get Call of duty 2 and Fear installed soon and do some testing with them.

All it does is make the game flip the framebuffer right after a screen refresh. Otherwise, the game would flip the buffers when the screen is still rendering, producing a 'tear'. Where the top half or so of the screen is still showing the old image, while the bottom half is the new image. It's personal preference whether you want it on or not. I, personally, don't like the fps hit (if it can't match your refresh rate it will divide your fps in half (unless your using triple buffering)). Some people just can't live with a little tear here and there, I don't even notice them that often, especially in slow-paced games SHIII.
