A file compiled with version 0.17b on Win XP is larger (of all non-cmd line examples I've tried so far) than the same file compiled with 0.16b (e.g. 98kB versus 83kB for a small file). I'm wondering if this is because the default libraries for 0.17 are larger? For pixel plotting, I've found a 0.17-c...

Yes, damn - might have a decent job if I could program like that.

Nice colour palette. Yes it is quite slow for a 320 x 240 window with screenlock (using a P4 3.2) (and it maxes the processor between plots). I tried it with 8bpp to see how much faster it might be... screenres sw, sh, 8 ...didn't make much difference, but did produce psychedelic colours. groovy!

Amazing - great concept and execution.
Very good for scenarios such as not being permitted to install FB on the PC used at the time.

Thanks anonymous1337 - that's really helpful.

On a PII 300:
(and keeping the fractal form (almost) constant with j=95 and k=45)

your ptr technique is almost twice as fast as pset (averages of 0.58 secs versus 0.99 secs).

I'm wondering about the better ways to plot a large-ish number of pixels (i.e. 200,000+) to the screen. I've noticed that some FB programmers first fill an array with the pixel information and then dump this to the screen in a second loop. (When I tried this technique on a 200,000-pixel fractal on a...

Nice and concise algorithm.
Thanks for sharing this.

Thanks - I had seen MichaelW's fast ASM randomiser - I'll search for some more and try to improve this aspect of the program. Well, since the probability of getting the jackpot in the UK Lottery is just a little better than 1 in 14 million, you have a way to go. - I was just surprised that a daft se...

Thanks to a posting by yetifoot I saw earlier today - this enabled me to bring my 'Lottery Wait' program (UK Lotto type) up to a decent speed. I expect this program has all been done before (and a lot better by someone else) - this one merely started from trying to convince my wife that she will not...

Thanks for your responses, and thanks MichaelW for your sort example. Think I'll stick wherever possible to the excellent balance of speed vs programming ease that FreeBASIC offers, and not get into knots with C. (From those shootout links: hope that mandelbrots in Python have only ever been develop...

I expect it's been asked several times, but from a cursory search, I can't find much about FB's speed in the forums. Speed must be difficult to quantify - depending on the task/PC spec/coding style used. With a simple fractal program (using a PII 300, so I could still see the plotting) my LCC-compil...

Looks good and comprehensive. Will definitely try out to get around some resource file problems.

Thanks. Your code amendment sorts the text alignment.

(I thought the gray text colour might be a problem - I noticed a considerable difference between an expensive 2-year-old TFT and a cheap new TFT screen [the cheap one was much brighter]. White text is a bit distracting for my eyes though.)

I did the following as a quick help for QB codes to color text in Screen modes 13+. Choosing RGB numbers just for text seemed hard work when I just needed a limited range of colors to compare and choose from. Perhaps it might be of use to someone else? (using a different gray number (18) in the draw...
