If Amiga had spread RTG it would have been more successful, AGA belongs to the past, RTG is the future.
RTG is comfort, space, more open windows, speed, and above all quality. |

IDK how RTG-like the 1280x1024 mode is, again you need power to drive the higher resolution (just as on any hardware platform today) but with the space available in the A1200 case it's a really good, maybe only option and leaves room for accel power. |

I used indivisions high-res modes. yeah they kinda work. but you for sure notices how slow AGA in at those resolutions. it is not fun to use at all.
4 color text for editing. sure yeah. works. anything else. not really |

In all seriousness, is there any AGA compatibility with demos, whatever in the Picasso 2 board? I've asked this elsewhere with no reply yet. |

AGA doesn't work on Shermi RTG, but if you have the right Monitor AGA and RTG can coexist.
On my A4000/060 that now sleeps in the garage, I had the Picasso Video Card, the AGA demos worked perfectly because I had a Commodore Dual Frequency Monitor that worked in both PAL and RTG, the switch between RTG and PAL was automatic and everything worked perfectly. Also on WinUAE it works like this, you can activate two Monitors and have AGA and RTG, always operating from RTG |

But do you really want to get rid of the flicker, I mean ultimately it's a part of what makes the Amiga what it is?

How much quicker in games was the RTG cards?

Although many (not all) commercial RTG games were sold on CD, many non RTG games were also sold on CD, and there are games earlier than 1995 that work well with RTG. Quote:

Just the commercial games are about twice what you estimated though (unless you have very different hands than me ), and there are at least a few PD/shareware games that should also be counted IMHO. |

No, although many late-era demos support both AGA/RTG. The Retina ZII boasts some fabled AGA compatibility, albeit very minimal/broken IIRC. Quote:
Depends: could be massively quicker if the game took advantage of PPC and/or 3D hardware. For software rendered stuff, and the (more typical) scenario of a Zorro RTG card and 680x0, practically no difference from what I recall. (Quake 1 timedemo was ~1 FPS difference between AGA and PIV/CV64 here--the Zorro bus and CPU were limiting factors.) However, the Workbench environment, and things like Mac emulation, are significantly improved even with a "lowly" Picasso 2 or Spectrum. |

What the Retina Z2 offers is most likely a software emulation that converts data by the CPU. I am not aware of a RAMDAC that offers something like HAM, or a VGA chip that supports more (or something different) than 4 planes. Otherwise, the Retina Z2 is a quite useless card as the NCR chip it is based on only supports segmented memory (no linear/flat framebuffer) and only EGS and some very old versions of P96 supported that.
Games and software can profit massively from the chunky mode RTG hardware offers as there is no chunky to planar conversion needed. However, it requires programs to use the Os interface to the hardware, there is no universal "hardware register set" as for AGA. Hardware-banging bye-bye. |

Yes, with RTG you can have big screenmode, you can play or work with high resolution, but softwares are developed for OCS and AGA (also ECS is very few in comparison). Myst is AGA and RTG, Quake is AGA and RTG, Napalm is AGA and RTG and also 202x games are AGA, OCS and compatibile with RTG, but you never find a RTG only softwares. You/we continue to find AGA software now and in the future because RTG is something little alien from Amiga philosofy that have enchated players, developer and fans thanks to his custom chipset (OCS, ECS and AGA), RTG is good for only high resolution, some little extras in games, but if you notice, you can use Amiga forever also without RTG. Exclusive 111 RTG games? It is that the question. Every RTG software you can run also with AGA, ECS or OCS. |

Productivity software (Pagestream, Wordworth, the workbench, Multiview, Opus...) all runs on RTG, and takes advantage of it. Ever tried to lay out a page on the rather poor AGA resolutions with poor chip mem speed? Quote:

Errr... With painful limitations. Pagestream with 640x512 PAL Hires Interlace on ECS as highest possible resolution? No, thank you, but no. |

For games that support it, RTG versus AGA is a pretty huge difference. And there are a few games that are graphics card-only. Wipeout 2097, Descent: Freespace and Earth 2140 are three that come to mind. Games like Napalm, Payback and Foundation are borderline unplayable at AGA speeds and resolutions, and are developed with RTG in mind. Being system-friendly games means, like the productivity software mentioned above, they can often also use an AGA screen. This is more a side-effect of the abstraction of RTG meaning any system screenmode can be used, than AGA hardware being deliberately targeted.
