- This is all true: however, the lackluster box is not the real problem.
- Rather, its that the PC architecture is 10 years old, and is seriously
- out of balance with the power of the 486. For example, I use my 486
- primarily for games, and it (a 486-33) is only capable of running about
- 8 fps on Falcon 3.0 with all the options set to max detail. On Aces
- of the Pacific, it slows down and becomes jerkey on ground-attack
- missions when there are buildings on fire.
-
- Theoretically, is the 486-33 with a copy-back 256kb second level cache
- fast enough to do the job well? Probably. But, when constrained with
- the aging ISA bus, the PC memory problem, that power is spent battling
- the architecture (both h/w and s/w).
