My Amiga 3000 desktop still in use today and why https://youtu.be/JXrM97yhbM8 ">https://youtu.be/JXrM97yhb... #RetroComputing
The tyranny of 60 Hz video refresh is oppressing these Amiga fans in the PAL regions and their CRT monitors. A lot of the demo scene rips to YouTube (C64, Amiga, etc.) are uploading directly in 50 Hz now. You can see the screen roll when you point a camcorder at a 50 Hz CRT.
Possibly he& #39;s using the 640x480 "productivity mode" at 58 Hz, but 640x512 PAL interlaced with the A3000& #39;s built-in flicker fixer is also a possibility here.
Productivity mode + 8 or 16 colors starts to bog down the chip memory access speed; unsuitable for unexpanded Amigas.

Never mind, that screen looks more like 1024x768, or 800x600 at the least. He must have a graphics card installed to get that resolution. You& #39;d think that Amiga graphics cards would use 60 Hz, but no, this was years before standardized mode timings. https://en.wikipedia.org/wiki/Coordinated_Video_Timings">https://en.wikipedia.org/wiki/Coor...
Ah, yes, he just said he& #39;s using a video card at 1024x768 x 24-bit color. That& #39;s a pretty nice video card if it can do that resolution at that color depth. Some of them won& #39;t let you do the maximum resolution at the maximum depth because the RAMDAC or video RAM isn& #39;t fast enough.
Oh, lol, I *own* the same video card he& #39;s using. It& #39;s the CyberVision 64/3D. http://amiga.resource.cx/exp/cybervision643d
1024x768x24">https://amiga.resource.cx/exp/cyber... is at the limit of both the CyberVision 64 and the 64/3D. It says the dot clock is "50 MHz @ 24 bit".

Oh, I see now why I was confused. The last time I had the Amiga 3000 and 4000 set up with the CyberVision cards, I was using my 1280x1024 resolution LCD monitor, and you& #39;re limited to 16-bit color at 1280x1024.
As this thread covers, all of the mid-1990s Amiga video cards are pretty slow by today& #39;s standards: https://forum.amiga.org/index.php?topic=61667.0
I">https://forum.amiga.org/index.php... was curious if anyone had done anything with the 3D in the S3 ViRGE/DX, but it seems no one has. The Amiga barely has 2D "retargetable graphics" (RTG).
