Date: Tue, 13 Jan 2004 19:25:37 +0300 From: Dmitry Yakimov Subject: [SDL] [PATCH] SDL bug patch Let me introduce 2 fixes to SDL. 1. Preventing great slowdown on fast machines while hardware flipping (it's obviously bug). 2. Setting up 85 Hz of monitor if supported. The reason is that Win98 by default sets lowest frequency 60 Hz. And we can't set up maximum frequency because some users can have wrong monitor drivers. This is important for shareware and commercial programs.
