The higher the res and color depth the more memory bandwidth you use. RTG on Vampire and Warp has shared memory, which is worth mentioning. ATI Radeon 9200 cards with lots of VRAM can show higher screenmodes. Vampire V2 accelerator cards can do up to 1280x720x32, while Warp accelerators can do up to 1920x1080x32. There is also about how much RAM is available for the graphics. The limitation is really up to what the graphics card can do. You can do more! What type of screenmodes can the RTG Amiga support? RTG is a recommended thing to have for your Classic Amiga. You can start custom Amiga applications that need Chip RAM much more often directly from AmigaOS itself without having to boot without Startup-Sequence. You have all of the mem available once booted. Then when you load up Deluxe Paint, Protracker, Demoscene production, or a game. So, let’s say you’ve got an Amiga 1200 or Amiga 4000 with 2MB Chip RAM. When you boot up any Classic Amiga with RTG installed. In Picasso96 you can specify how much RAM of what you have can be used for graphics mem. AmigaOS will use the VRAM as memory or if you have a lot of RAM that can be used as VRAM too. This means that when you boot up any Classic Amiga with a graphics card installed. If you want to use multiple MUI screens on RTG Amiga, you need to have more than 64MB RAM to show several screens in 1920x1080x32. It is however recommended to have more than 32MB RAM to be able to use AmigaOS without issues using a graphics card that is supported by CyberGraphX and Picasso 96. This specifically includes the old V2.0 version, which is also the property of iComp GmbH.īoth CyberGraphX and Picasso 96 require at least 4 MB of Fast RAM or VRAM and a 68020 CPU to operate. The only source for legal registration of the P96 software package is the Individual Computers website. Re-distribution of this archive remains legal, as long as no money is charged and no claim about registration is made. There’s a shareware version of Picasso96 (v2.0) and that package does remain active. In the beginning this package had issues with CyberGraphX system, but these issues were solved. Today Individual Computers develops updates for registered users. Picasso96 was selected as the RTG standard for AmigaOS 4, at first released as a 68k binary in AmigaOS 4.0 pre-release. Including being a well-made API system for the Classic Amiga. You have to do more it seems to get applications such as TVPaint which is an RTG 24-bit paint program to see all of the screenmodes. It is not of the same quality as CyberGraphX but it does its job well enough when the drivers are developed enough. The development began its life back in 1996 by Village Tronic (biggest competitor to phase5) which is known for the Picasso II, Picasso II+, and Picasso IV RTG cards for Classic Amiga. But now it is Picasso 96 that’s been taking the lead as it is still in heavy development. Being available free of charge for users of supported cards, CyberGraphX became the de facto RTG standard for Amiga. EGS can only run software in its own environment. CyberGraphX V4 is all for Classic Amiga, but V5 was released for MorphOS only.ĬyberGraphX was the first RTG software to allow full true-color screens for Workbench and applications. It is developed by Thomas Sontowski and Frank Mariak. This one was introduced back in 1995 with the CyberVision64 from phase5. EGS was made in 1992 and it was developed by Viona Development and was made available for Piccolo and Spectrum graphics boards, supporting screen depths up to 24 bits. One other RTG standard system for Amiga that tried to establish itself was EGS, but it couldn’t run AmigaOS software as Picasso96 and CyberGraphX can. Their names are Picasso 96 and CyberGraphX. There are two common APIs for AmigaOS that is almost compatible with each other. It is a device driver API mainly used by third-party graphics hardware to interface with AmigaOS via a set of libraries. The name RTG stands for Retargetable graphics.
