is messing with the video buffer worth the speed?

Everything else that doesn't fall into one of the other PB categories.

Post by Dreglor »

i was thinking if there were any ways to speed up plot commands
and i read in the help about having access to the video memory directly
for "fast pixel manpulation" is it really any faster?

It's about 2 times faster when doing it correctly. Of course, it depends of your program, if the plot() only represent 10% of your computation, you will not gain a lot of speed.
