[Patch] Default video timing

Postby leilei » Sun 05 Nov, 2017 9:41 am

This is a pretty quick patch that gives rough estimates of loosely based on results on vgamuseum.info (after basing the timings off the preset timing speeds applied appropriately first while running DIAG/PCPBench/Quake to keep polishing timings sort of closer). These default timings are accessed with a new menu choice after Fast VLB/PCI (ideally i'd want it to be a -1 before 8-bit...)

In this initial patch, a lot of the timing on the older cards are going to be off (I didn't do much time on research on the non-VGA hardware), and to tweak the timing on the faster cards I had to test with fictional 1000mhz PMMXes to get the cpu bottleneck out of the way for Quake and PCP...
