I posted this in the 'Driver' section but didn't get anywhere. So, sorry if the double post bothers anyone, but I'm pulling my ****** hair with this - I just can't sort it...I recently upgraded my nVidia drivers and installed the new(ish) 'Inspector'.Having only an 8800GTS, the benefits were in the negative, so I removed the driver (properly), reverted back to 197.57 and reinstalled nHancer.HOWEVER... Since then, the external 'Frame Limiter' simply will not lock FSX frames.This is driving me nuts. Any idea what's going on?Here is the batch file:start D:\"! FS DATA\!4 MASTERS\FPS Limiter\"FPS_Limiter.exe /r:D3D9 /f:30 /x:OFF /l:OFF "F:\Flight Simulator X\fsx.exeIt does launch FSX, so SOMETHING is working.Using the built-in FSX limiter drags my system right down when I try to use it.Thanks

The "x:OFF switches off the FPS display Dougal, to show it hit F12, just in case you missed that setting.Apart from that the command line switches look OK to me.
