- How do you define "the PC"? The current base level PC is a Pentium 90
- with at least 8MB RAM and a PCI graphics card that has mem-to-vmem
- transfer rates around 50MB/sec. When it comes to 3d graphics it would be
- a bit hard for a 030 machine to "blow" such a thing "away".

- A "pixel intensive" 3d game, where it takes 3..10 instructions to
- render a single pixel cannot expect to get a big performance boost
- only because a better SVGA card is used.

- PCI gfx boards are dirt cheap (around $150). At least they
- are way cheaper then Amiga gfx cards.

- First, lowcost 3d cards exist, I have a Creative Labs 3D Blaster in
- my pc. Ok, it's slow as hell and I would never have *bought* it, but
- that was only the first generation, but now they know what's up
- and push the 2nd generation to the market.
-
- The useability of such cards is not defined by the card itself,
- but by the (software) driver system that the games are using.
- If a function is not supported in hardware, it will be done
- in software by the driver. Another card may offer this particular
- function in hardware. The big question for the game companies
- at the moment is not, which 3d hardware to support, but which
- 3d Game API will rule the world in 2 years [it will be Direct3D
- for the Wintel world whether it sucks or not].
-
- Conclusion: The Amiga needs PCI, and a ***driver***system*** for
- 3d hardware accelerators. It does NOT need yet another obscure
- custom hardware. The big game companies WILL publish their games
- first for the PC, then probably for other machines, but only
- if the port will be cheap and easy.
