For people who get that big green onscreen FPS display or who want to change the frame rate.

I am not sure what J. M. Pescado  has taken out of the FPSLimiter.
But as it was when posted originally on this thread;
 (http://www.moreawesomethanyou.com/smf/index.php/topic,15092.0.html )
You were able to control the Max limit and on screen display.

I suspect that these keys may still work and maybe worth a try.
"keys to change the desired fps (F10 decrease / F11 increase)
 ingame fps display, show or hide with F12."
Hope this helps.

If I was getting  67°C with vsync on I wouldn't bother with this limiter Viviane.

My old computers graphics card (nVidia 6800) was getting core temperatures up to 127°C.
I am surprised it hasn't died on me yet like my older ATI9800 pro.

The one I use now (nVidia 8800) is just a little above 90°C while gaming, with its fan duty cycle at 100%.
I like to keep things quite, fan 60-70% and temperatures under 80°C.  The limiter helps me do this.

Sounds like you don't have any overheating problem.
Your card is running cooler while gaming than mine is when just idle at the desktop, which it does at  76°C
