    its for vsync. What it does is render the frames faster than how they display on screen.
    For example if you've got vsync on and a monitor refresh of 60hz it would render 3 more frames (63) for smoother transitions.
    The more you put it the bigger the performance drop so in the end its personal preference.
    Everyone will recommend 3 though because you wont really see much of a difference past that.

    Setting it too high may introduce mouse lag. I used to use 3, but with faster cards I ended up droping it to 2.

    BTW, it had no tie-in with vsynch. It will try to prerender even with vsynch off, which is how you end up with mouse lag if you set it too high.

    People often confuse this setting with triple buffering, which IS tied to vsynch, and which allow for smoother transitions by having more frames ready for display as each frame is drawn.

    P.S. To answer your zeroing out question; that will stop prerendering. It is probably not required unless you get serious mouse lag with it set to anything higher than 0.

    Here's your answer: triple buffering
    Originally, this was 2D only. The option you're asking about does the same thing, for 3D.

    this isn't true.

    uhh... it is vsync. I don't see where you got that logic from.

    doesn't even work for me. I set it to 50 did nothing with vsync on or off.

    dboniuk is right

    it doesnt have to do with vsync

    the lower you set it (ex 0) the more responive input you get...so you get less mouse lag but also lower FPS. a good normal setting between mouse lag and FPS is around 3..some games need lower for no mouse lag though such as Oblivion performs smoothest with this set to 0. once again you don't need vsync on for this. it doesnt matter.

    I always found 0 to be best with my 6800gt/7800gtx/7900gt, but 3 seems fine with the 8-series. In fact I don't think 0 even works with the 8-series, last time I tried it it was unable to run 3d apps.

    thanx anyway..but it lays under the VSYNC topic in the Rivatuner..i'm just playing with it to solve @ the NFS ProStreet's Stuttering problem..i do this,cuz i believe this game's lag problem is caused by a VSYNC problem,cuz when i close it,game stutters much more,when i open it,it stutters less but not stops,anyway..

    I thought the prerender limit cannot be set lower than 1 on NV cards for OpenGL programmes? Since 1 is the minimum for Nv cards.
