yes thats it.
the first line of writing, i forgotten what it says.
but chnge the 0 or 1 to a 1 or 0. (oppsosite number)
then save and exit, then go into game and enjoy,
if it is too much and still to slow, then go back out of game, open f1graphics.cfg and change back t the standard number (1 or 0)
then open game, reduce some of the settings, and then save and exit and go back into the graphics file and change the number again.
keep doing this until you have reached a good level of performance.
ps: i would leave fps at about 30.
