-

-
- You rely on _programming crap_ in combination with low cpu.
-
- 99% of all games are coded to crappy to see AGA bandwidth as
- real limit!
-
- : Agreed. AGA is *really* crap. Who cares if we can C2P a 2x2 screen

- : fully texturemapped/shaded games in two frames.
-
- In two frames ? You must rely on a P133 system, with very good
- board & mem! If you can afford an Amiga which got same power,
- you surely can afford a gfx card, too.
-
- BUT: you can't tell that AGA is the big prob for a 030-50.

- : >four times to get 2x2?
-
- Yes, if the VGA got no blitter, then AGA is faster on A1200
- doing 2x2.
- Quite lots of those cheap-PC-gfx-cards are 16bit, and 16bit fastmem
- is not lot faster than 32bit chipmem on 020-14, so even almost
- same speed on 1x1!
-
- I didn't claim more...
-
- : Which btw is bullshit.. On PC you can also set vertical line height,
-
- no. you didn't understand the claim.
-
- : and if you put it in tweak mode you get a free 4-pixels wide

-
- but then you got to copy _bytewise_, making use of the 8bit latches
- of the old EGA modi! Don't tell stories here ;) Writing bytewise is
- slower than the longword writes to AGA-chipmem!
-
- I'm not 100% mode-x expert, but imho this time you wrote bullshit...

-
- You don't believe me that 1mb fast is a lot better than 0mb ?

-

- 10bit is for example faster than 16bit, for your information.

-

-
- Well, 1024 palettet colors are not that bad imho...
- would overrule 16bit displays in good-looking and
- 24bit displays in speed when doing shaded textures.
- Of course a 16bit-to-planar unit would be needed.

- huh logic ? There is no clone because nobody programed it. A clone

-

- the C2P problem on 040 is a PCer myth! C2P doesn't make it worse.

-
- Well, as chipram is in the same box like the 060, it's radio
