I ran Captain Zero in DB Pro today and asside from some understandible differences, it went uber slow! I can't figure out what's slowing it down from db1 to dbpro. What up with that? any ideas?

There are lots of reasons why this could be slow. When I compiled my DB1 project to DBPro it ran slower. DBPro uses DX8 so you have to have a compatible Gfx card (in other words one that runs DX8 fast), if you don't then it'll definately run faster

The response I've always got is that DBPro isn't DBV1 and you shouldn't expect the code to run the same

If it makes you feel any better I'm rewriting mine at the moment (structures make life much easier!)

When I have had crashes in DBPro its always been down to a specific command, sometimes when placed in a particular location (such as a function). I can only suggest 'REM'ing large sections of you code and seeing if you can pinpoint whats causing it (there was a note on a fix in release 3 for a bug where untyped arrays in functions causes a crash).

On the slowing down there are a few commands which are slower that DB (see http://www.darkbasicpro.com/apollo/view.php?t=1874&b=1)
I would recommend using the timer function to show you how long parts of your code are taking, then you should be able to narrow it down to a specific command and see if you can work around it.
