i run warcraft2 with vdmsound... the sound is great but the game run choppy because the lack of resources... when i open task manager i can see that ntvdm.exe is using 100% of the cpu..
any ideas?
This is a "known" problem with NTVDM in general (NT4, Win2k, XP), and as far as I can tell it's by design.
You can reduce the % CPU usage by going for "reduce CPU usage" in the Performance properties for LaunchPad (equivalent to the idle sensitivity in .pif files), but since this messes with the DOS timer emulation (which is what accounts for the 100% CPU usage) the sound might break up.
NTVDM will go 100% always no matter how slow or fast the machine is, and apps will perform the same be it a 120MHz machine @ 100% CPU usage or a 1GHz machine @ 100% CPU usage. Take it "as is".
