-
- you're now arguing about the market thingy. Let me just again stress,
- the chipset won't make it expensive to port.
- I got the impression that ID didn't want a Amiga port, even if they
- were given one for free. Obviously it would jerk on a base A1200.
- No reason to keep someone from playing it on a base A1200 if he
- wants to.
- Anyway the funny phobia of id against an Amiga version (speculation)
- was hidden by doing wrong technical statements about Amiga (fact).
-
-
- THE DOOM TEST: technical facts
-
- I tested doom on a 386SX-25. Yes, it jerks, that's not my point.
- The 386 is about same speed like my 020-14 with mem-axpansion
- (see specs).
-
- My point is that doom runs on the 386 quicker than Textdemo57
- on my 020-14 + fast.
- TD57 is the best clone I know, and seems the newer ones are
- also wasting some cycles somewhere (if I interpret reports
- right).
-
- SECS of this 386:
-
- copy mem->mem: 5.5mb/sec vs. 8.5 mb/sec on 020-14
-
- non-shaded-linear-map: 0.88mb/sec vs. 0.8mb/sec on 020-14
-
- it is also likely that the bsp code is of that kind (little
- mem acess, lot reg,reg operation) that is up to 20% faster
- than 020-14.
-
- copy fast->VGA-ram: 1.75mb/sec, i.e. 0.036sec for copying a
- 320x200 screen.
-
- vs. 4.4mb/sec blitterscreen (real chunky) on 020-14+AGA.
-
- CONCLUSION:
-
- - a port of original doom (including 4.4bm/sec c2p) would be
- fastest tmap game on Amiga, so there is still room for lot
- improvement softwarewise.
-
- - slow clones are not AGAs fault even on higher speed cpus,
- I showed calculation examples often enough. up to now too
- slow clones were result of non ideal code.
-
- : to require Pentiums. Even if the Amiga DID have a chunky mode they are
- : no match at all for a Pentium when it comes to power.
-
- Even if my Amiga did have a chunky mode, it still would copy
- 4.4mb/sec to vram, no difference.
-
- So most important thing is a fast cpu & some mem.
- The new Amiga "walker" looks like a good machine for
- tmap gaming (that's my point), but Amiga just lacks the game!
-
- : And if the did port stuff - imagine all the flames here because they
- : didn`t spend time optimising it all for the Amiga etc.
-
- It's almost all in C. A good port includes the various routines
- available. Many freaks would help if you port doom. A ideal
- port will do c2p+copy to vram at 4.4 mb/sec even on 020-14
- (and it'd support gfx-cards!).
- chunky 4ever :)
