Make sure to run FText after FBlit. Run WBCTRL at the
end of your startup, right before the LOADWB line is
a good idea.
WBCTRL IMT=ICONFAST
and after that:
LoadWB SIMPLEGELS
Then go to your Workbench prefs in sys:prefs, and set
it up to store images in "fastram". That should speed
things up a bit, whilst not using much chipram for
on-screen icon display.
You may also want to try and run FBlit in "exclude"
mode...this will exclude from promotion only the tasks
which you specify in the FBlit prefs. That way you can
be sure that pretty much anything ran on your WB will
be promoted (IBrowse runs much better this way f.e).
--edit--
And as Rob72 pointed out, SystemPatch is a great
replacement for FText and BlazeWCP, among other
things.
