Core timing mode? #74

Closed reignerdeustcher closed 2 years ago

reignerdeustcher commented 3 years ago

It says that internal introduces lag and judder then what is the point of using it?

It's for running 70Hz DOS games (there's many of them) on 60Hz displays without tearing. It's not only 70Hz games though. Sometimes, games use weird VGA modes that use oddball refresh rates. Normally the best way to run dosbox is on a VRR display (g-sync/freesync) at the highest refresh rate your display supports. But if you can't do that, then internal mode can be useful to get rid of tearing.

Don't use internal mode then. Use external mode and configure RetroArch to use VRR (https://www.libretro.com/index.php/category/g-sync/)
