My Amiga 3000 desktop still in use today and why #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's using the 640x480 "productivity mode" at 58 Hz, but 640x512 PAL interlaced with the A3000'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'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
Ah, yes, he just said he's using a video card at 1024x768 x 24-bit color. That's a pretty nice video card if it can do that resolution at that color depth. Some of them won't let you do the maximum resolution at the maximum depth because the RAMDAC or video RAM isn't fast enough.
Oh, lol, I *own* the same video card he's using. It's the CyberVision 64/3D. http://amiga.resource.cx/exp/cybervision643d
1024x768x24 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'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's standards: https://forum.amiga.org/index.php?topic=61667.0
I 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).
