Talk:Vertical blank interrupt

VBI and modern protected mode operating systems
The article says:
 * ''Modern protected mode operating systems generally do not support VBIs as access to hardware interrupts for unprivileged user programs could compromise the system stability. Instead, various APIs like DirectX provide efficient and safe ways to present graphics free of tear and flicker.

'' But don't these operating systems have to use this hardware function themselves and then simply offer the userspace software an API interface? 84.158.114.152 (talk) 17:07, 7 July 2024 (UTC)
