V-Sync Question.

I have a little issue with Vertical Sync capping my FPS.

I know V-Sync caps it to the refresh rate but for some reason, my FPS is being limited to exactly half the refresh rate. I normally play with 75hz which is giving a 37.5 fps. I tested with 60hz and it's 30 fps.

Because the values are exactly half of what they should be, have i missed something?

I'll be posting up the CoH helper and hijack this stuff shortly.

nope, not missing anything.

Vsync will do this when your FPS drops below the refresh rate just so that it remains in synch with the monitor.

VERY HANDY GUIDE ABOUT GRAPHICS AND STUFF (direct linked to Vsync section, but other stuff is handy)

Quote:
When VSync is enabled, what happens is that your graphics card is told to wait for your monitor to signal when it's ready for a new frame before supplying a single whole frame, each and every time. It can't race ahead, it can't just pump out lots of partially completed frames over old ones whenever it's ready - it has to provide a single whole frame to the monitor whenever the monitor says it's ready to refresh itself during VBI. The first noticeable impact is that your FPS becomes capped at a maximum equal to your current refresh rate. So if your refresh rate is 60Hz for example, your framerate can now only reach a maximum of 60FPS. By itself this isn't really a problem, since every monitor can do at least a 60Hz refresh rate at any resolution, and as we've discussed under the Frames Per Second section, if your system can produce 60FPS consistently in a game this should be more than enough FPS to provide smooth natural motion for virtually any type of game.


There is however a more fundamental problem with enabling VSync, and that is it can significantly reduce your overall framerate, often dropping your FPS to exactly 50% of the refresh rate. This is a difficult concept to explain, but it just has to do with timing. When VSync is enabled, your graphics card becomes a slave to your monitor. If at any time your FPS falls just below your refresh rate, each frame starts taking your graphics card longer to draw than the time it takes for your monitor to refresh itself. So every 2nd refresh, your graphics card just misses completing a new whole frame in time. This means that both its primary and secondary frame buffers are filled, it has nowhere to put any new information, so it has to sit idle and wait for the next refresh to come around before it can unload its recently completed frame, and start work on a new one in the newly cleared secondary buffer. This results in exactly half the framerate of the refresh rate whenever your FPS falls below the refresh rate.


As long as your graphics card can always render a frame faster than your monitor can refresh itself, enabling VSync will not reduce your average framerate. All that will happen is that your FPS will be capped to a maximum equivalent to the refresh rate. But since most recent monitors refresh at 60Hz, and in many recent games it is difficult to achieve 60FPS consistently at your desired resolution and settings, enabling VSync usually ends up reducing your overall FPS. Fortunately, because this problem is pretty much caused by the frame buffers becoming filled up, there is a solution: enable a third frame buffer to allow more headroom. However this is not a straightforward solution, and to read more about it see the Triple Buffering section of this guide.

Enabling triple-buffering in the Nvidia Control panel will boost your fps with v-sync on.

Cheers Gangrel. Wasn't aware of any of that.

And thanks Cynical_Gamer.
