Re: ANNOUNCE: DEMO version of E/D beta0 available



E/D 2.0beta0 also has a new command line switch:

executor -dangerousvideospeedup

If you have VBE 2.0 (type "executor -info" to find out), a linear
framebuffer on your card (true for almost any recent card), and you
run Executor under Windows 3.1, Windows '95, or OS/2 Warp, you may
find this switch interesting.  It isn't necessary under plain DOS
unless you are using QDPMI or some other DPMI server besides CWSDPMI
(which comes with Executor).

"-dangerousvideospeedup" allows programs that bypass QuickDraw
(e.g. games like Maelstrom, Swoop, Solarian, Apeiron, Space Madness)
to run without needing "-refresh"!  This will make them run *much*
faster, although problems with accurate timer emulation on such
systems may negate the speedup for some games.

The drawback to this switch is that it makes it more likely for a
misbehaving Executor to crash your machine.  "-dangerousvideospeedup"
bypasses some memory protection that would otherwise prevent an
Executor crash/malfunction from affecting other parts of your system.
If you use this switch, it's possible for data elsewhere in your
system to get corrupted, so USE WITH CAUTION!

I'm interested in any feedback on the behavior of this switch.  It
made a huge difference for me playing certain games on ARDI's 486 DX/2 66
running Windows 3.1.
