None of these tweaks are working. 🙁 I've improved the stability, but its still pretty much a certainty that the game is going to crash every 20 to 30 minutes.
I'm debating if I shouldn't put some effort into refreshing one of my Inspiron 531 test machines with some decent hardware. X2 5600, Radeon 5750, and a better PSU aren't terribly expansive, would work in the Dell motherboard and prevent the purchase of an OS license, and I logged 33 hours of OT this pay period. Work case, I suppose I could install my old copy of XP on it if Vista 32 becomes just as problematic.
Suppose, I could also go though the effort of setting up a dual boot between Win7 64 bit and XP on this machine, though I'm running short of hard drive space and I'd lose more than half my 8GB of RAM while running in XP. Also, hose my uptime having to reboot to XP. A VM is probably out, as the GPU support isn't up to that level.
