-
- It depends on what`s currently eating Chip RAM. For instance,
- before I added the gfx card to my setup, I used to go through
- a well rehearsed routine when I wanted to run a Chip RAM
- hungry bit of software from Workbench:
-
- Close all the windows
- Remove the backdrop images
- Reduce the screen to 1 bitplane
- Reduce the resolution (only in extreme cases)
- Run the software
-
- Now I just:
-
- Run the software
-
- because whereas originally my Workbench screen was sitting in
- Chip RAM, now it`s sitting on the gfx card, and therefore
- consumes approximately zero Chip RAM (after WB has finished
- loading, I have 1.9MB free Chip RAM, compared to approximately
- 1.2MB free without the gfx card).
-
-
- But note that I still only have 2MB of Chip RAM in total,
- the gfx card does nothing to alter that limit. All it does
- is let certain well behaved bits of software run on the
- card instead of the AGA hardware, which frees up Chip RAM for
- those programs that absolutely MUST have it. But it doesn`t
- extend the Chip RAM limit beyond that imposed by the
- custom chipset, so a 1MB Chip RAM Amiga will still be a 1MB
- Chip RAM Amiga, gfx card or no gfx card.
