- The nice thing is that the Amiga DOES it while all programs I
- saw on VGA (linux/x) use the blitter.
-
- Even if the VGA blitter was fast enough, all current OS-based screens
- jerk just because the mouseupdate is not display synced. (timer, no
- vblank interrupt used).
- And the serial mice were reported to be not fast enough for sending
- coordinate data in 50Hz :D

-
- : Sorry, that's nonsense. SVGA cards can do fullscreen scrolling just
- Yes.
- : like the Amiga can, the only difference being that parallax is easier
- : on the Amiga due to the planar display. I'm using a Linux box here
- : right now with a 1280*1024 screen, and it scrolls beautifully.
-
- I bet below 50hz! (or is it linux on Amiga ? :)
-
- : Give it up, for goodness sake. The days of custom hardware are
-
- The Amiga mouse & virtual screen go 50Hz due to custom hardware.
- New consoles do fancy games due to custom hardware.
- custom hardwardware is made for its speed.
-
- : *over*. Today, the operating system is everything. You argue that
-
- yes, and the Amiga one allows use of custom hardware => 50Hz.
- I also vote for API driven special hardware.
-
- : standard hardware will stop people writing Amiga games. Look around
-
- sorry, this is blah. Those assumtptions about why amiga market
- is low are mostly just wrong. And nobody will stop people going
- on writing software for Amiga. look on aminet.
-
- : you! The Amiga games market has gone, dead, finished, and you know
- : why? It's because the custom chipset makes games expensive to port,
-
- NOT! Take ID's DOOM (it's written in C), rewrite the little
- asm parts (they say 2 asm routines).
- Then, for taking care of custom chipset, i.e. planar mode, add a
- c2p routine from the net. voila. (but those ba****** won't allow
- a port).
-
- well, game ported, without having done a single move to hardware.
-
- : and with a vastly smaller userbase it isn't practical. If the Amiga
- : used standard hardware, we'd get more games because porting them would
- : be very easy indeed.
-
- not. you could use this excuse some years ago, due to the c2p algorithm
- beeing not easy to do.
-
- but, today, name the PC game you want to port, and your mailbox
- will be flodded with freaks messages sending you c2p routines or
- references to them on the net. no problemo.
