Do you have a 64-bit operating system? AFAIK the latest (or in fact all) version(s) of Fraps have a bug where they simply won't work on some WinXP 64-bit systems.
hmmm, i have a 64-Bit CPU (an overclocked 4000 Sandy), but am using the "normal" 32-bit version of XP, could this be why fraps refuses to record anything (i press the button and get nowt!)
I installed fraps 2.8 b6345 full oveer the 1.9 demo without any problems. Records fine however sometimes my fps is good and other times bad, haven;t worked it out yet. Still need tio find a way to run fraps on one core and LFS on the other core, so far no joy.
