Hi guys. Bumping an old thread again. Sorry.
I played WC1 and 2 in KS without issue, got to 3 and had no issue until after I talked to Vaquero for the first time. Then it locked, and had been unplayable ever since.
Then I discovered and applied the Win2K patch, but still no luck. I tried all the compatibility modes, and still nothing. I tried VDMS to no avail. Nothing worked.
I was getting ready to mess with sound card acceleration just for giggles, and noticed in this thread that hardware and OS and SP and DX had all basically been ruled out. Including various combos, even mine.
I decided to do a little maintenance and hit Windows update (still on SP1 and plan to stay there, at least for a bit), got everything they had except for DX9c and SP2. Then I went to Creative and got a new driver for my Audigy.
Then I decided to try the alt-tab priority change method. With compat mode on, it's in normal to start with, but would still lock up between movies. And previously I was unable to alt-tab at all, only the 3 finger slaute worked. But, for some reason it started working, and w/o compat mode on, it's in high priority again, and changing it to normal really does do the trick. But I can't run for too long. I have to follow the old Sierra game motto - save early, save often. It still never locks during a scene or combat, only in between.
40.72 is a very early driver. I'm glad I didn't have to try that. I'm on 61.77 (GF4Ti4200), and also just got the most recent Audigy driver available.
Since hardware basically been ruled out, it looks like it's down to driver combos. (that would be my guess at least)
