One thing you must consider is that the Amiga has a lot less bandwidth
available on it's graphics bus, and to some extent on it's memory bus
compared to PCs. The PPC cards are (I hear) quite good for memory speed,
all things considered, but don't forget that they still use SIMMs at
60ns rather than the faster memory types used in modern PCs.
Try this, reduce the game window to the smallest possible setting. Even
though it will probably be (if it's anything like the Q1 engine) only a
few cm accross, you will see that it runs at a fair rate. There simply
isn't as much bus activity. Even at 320x240 there is a considerable
amount of data to move when copying the screen buffer alone.
Wait till we get G3s and PCI graphics cards, the difference will be
noticable in the same way as my friends Z2 system is noticably slower
than my Z3 one, especially for games.
