I am curious about whether there are certain games or for that matter hardware (probably early proprietary stuff) which FORBID 60hz gaming and thus may be a challenge to capture with the most common video capture hardware.
This includes everything from the dawn of the PC to about the XP era after which everything allowed freedom of resolution that I know of.
For instance the Hercules graphics adapter was apparently 50hz - no matter what. Not many games used it (though one used it as a secondary monitor, Back to Baghdad i just found out) though perhaps it would capture with PAL type settings.
All CGA and EGA are 60hz. VGA I always thought was 60hz but apparently 640x400 and 320x200 are 70hz - so i'd imagine capturing this might be a problem afterall. I'd always thought typical games were 320x240 though...
SVGA and the early 3d accelerators is where things get tricky. Were there any games that, as programmed in software and menus who at any higher resolution REQUIRED a higher refresh like 70hz or 75hz? (no option for 60hz)
The Rendition 3d accelerators apparently played certain games at 75hz only possibly all games. Worse they would switch frequencies while playing between menus and 3d gameplay! 😜 (i've no clue what that will do to a capture card)
The S3 Virge 3d decelerators apparently wanted to play at 70hz, possibly all? Ie I cant find out if even normal VGA-ish modes like 640x480 were then at 70hz as well.
Mostly i'm trying to find if there's ever been something outside of the seeming standards of 50, 60, 70, and 75hz that might require an oddball or custom capture solution since i'm hoping to start doing some retrogame playthrough stuff on youtube sometime soon focusing on rare and obscure titles. Although it's technically off topic for the board, if anyone just knows offhand of any other arcade, retrocomputer or retroconsole which actually used frequencies outside of this they could comment as well. (for instance some japanese shooters apparently run 56hz refresh in the arcade - i've no clue why or what alleged advantage that would have)
