-
- What do you do with 50MB/sec of "transfer rate"? Just *transfer* animations?
- Maybe from your 600K/sec CD? Or you render gfx on screen? Making with the
- CPU most of the job that a video device should do.
-
- Personally, I never said "we'll blow PC away using PC routines", I said that
- making things differently and having the right (programmable) video hardware
- it will be just another story than today, and yes: I meant to set the standard
- in computer games. 3DO-M2 is not a computer, PC is.

-
- Agreed, as I repeat since years back.
- A lot of people are convinced that stealing the SVGA board from a PC and
- putting it into their 50Mhz Amiga will make it fly. Actually, it will make
- it *much* slower for everything that is not Doom, where the improvements
- will be ridicolous (but remember it's 100% a PC game as programming methods).
- Not talking about nice (but static) WorkBench screens here.

-
- Amiga GfxCards have nothing to do with Amiga, you know. They're again SVGA.
- Of course a PCI SVGA board is better than a ZorroII SVGA board, but what's
- the matter?

- Yeah, untill P6 comes out and we're back again.

-
- Yesterday I heard the latest thing Direct3D cannot make and thus is not being
- used for the coolest games. Developers are masochist to want to make 20
- different versions for any gfx chip, or the whole API/realtime_games topic
- is naive?
