vSync "on" forces the graphics card to display the screen image at the same rate (fps) as your monitor's refresh rate (typically 60-75Hz). As your monitor cannot display individual frames any faster than it can refresh, there really isn't any point in having vSync "off" except to massage the ego! :DL I normally run at about 150-200 fps in external views and 400-600 fps inside the boat, but as my monitor has a 60Hz refresh rate, it's all but meaningless in terms of image quality. If you really want to improve fps rates under extreme conditions (the massive explosions that sometimes occur when a ship is sinking is a good example) lower the particle density setting to about ⅔ (60 in the SH3 options). It has almost no affect on the look of SH3, but stops the pretty severe fps drop from happening (on my machine at least). The plus side of having vSync enabled is that it stops the horizontal "tearing" that is sometimes evident. Stand on the bridge when in port (lots of stuff happening in-game, ships moving around, aircraft flying over etc etc) then pan round to the left or right fairly quickly. You may notice that the screen image appears to "tear" at places across the screen as one part of the monitor is still displaying one "frame" while the other part of the monitor is still displaying the previous "frame". If this is severe enough to be distracting or annoying, then enable vSync and that should stop happening. My installation of SH3 doesn't have that problem to any great extent, so I've left vSync "off", but in my Morrowind installation it was pretty bad, so I've forced vSync on through nHancer and it now runs at an almost constant 50-60 fps regardless of what is happening onscreen - with no tearing. Apologies in advance to all the computer gurus out there for my over-simplification, my level of expertise is about as low as my years of age are high! :DL
