As said, I believe -crf 0 is lossless (or at least high quality).
You can test the following command line that is visually lossless:
$ ffmpeg -f x11grab -r 30 -s 1920x1080 -i :0.0 -qscale 2 out.avi
I still suspect you don't like the conversion from rgb to yuv,
none of the "typical" encoders support rgb.
You can try the following to test if you prefer the output:
$ ffmpeg -i x11grab -r 30 -s 1920x1080 -i :0.0 -pix_fmt png out.mov
x264 does support encoding rgb (-vcodec libx264rgb) but
please remember that neither WMP nor QT will play the result.
Please read http://ffmpeg.org/contact.html and understand that
thread-highjacking should be avoided.
