- Standard DOOM.WAD (4234124 bytes long), Falcon with FX-card installed

- You can see that the speed of new version of BM is nearly exactly half of
- speed of the original DSP version of BM132a. Furthermore you can see, that
- the FastRAM is fine but not neccessary. Hopefully I can't test the BM with
- DSP @ 32 MHz, someone other probably can (and please, do it).
- Interesting is, that 32 MHz is faster than 20 MHz, that means there's a lot
- of CPU computing in BadMood (in usual applications the 20 MHz is faster
- thanks to faster data bus).
- The sign `:-((' means that my FX-card is not running at full speed with
- FastRAM, so please if there is a happy man with running FX, fill out the
- missing numbers and tell me, which version of FX software you use, thanks.
-
- The best machine would be Falcon with FX-RAM running at 40 MHz, but it still
- won't be close to 10 fps.. Falcon is not very fast even with its overclocked
- DSP :-( Waiting for the Afterburner results ;-)
