Nirth_90: With an nvidia card and one of the later drivers along with nvidia inspector you can add a frame limit to specific game profiles between 1 and 120+ I think. It works great especially if you're annoyed by VSync's input lag or if the game doesn't support either VSync or a frame limit.
I don't know if this exist for ATI/AMD cards but maybe.
tiv: Thank you - the frame late limiter does help with the input lag! What FPS target gives you the least tearing?
I don't think a frame limiter helps with that, you need a second buffer like VSync and its function is what causes the input lag (if I remember correctly, could always good the term or read at wikipedia). I'm not sure how annoying input lag is in this particular game, haven't had the pleasure to test it yet but it differs from engine and type of games. If tearing is annoying try running with VSync (and preferably triple buffering to avoid performance issues). To force triple buffering you need a specific tool for that, a famously used one is D3DOverrider, a separate program that comes with RivaTuner. It's available att Guru3D, they have fast download servers as well.

http://bit.ly/IHGopG Just remember to update it. Glad it worked out for you with your current application, always nice when you don't need an application for every little option.
About specific FPS, it's very optional so in case you run a high-end GPU but isn't bothered by some lag you could always lower the limit to avoid addiational heating although it shouldn't be an issue as long as you have a working fan and great airflow in the case.
I can't wait to play this myself but I'm hooked in Planescape Torment at the moment and I have hard time focusing on two single player games simultanously. *hmphf*..
