First I’ll say the conversion’s fantastic. You folks really understand what made the original great, and even how to improve on what hindered it.
But, my game starts stuttering at random. Sometimes I play for 15 minutes before it happens, sometimes an hour. Then, soon, any keystroke gets a “beep.” Then before long it crashes to desktop.
As requested, I’ve attached the minidump. I couldn’t get a proper screenshot of the showbudget panel, but there were clearly spikes in SOUND and SWAP CACHE whenever it started stuttering.
I tried the suggested fix for multi-core processors. It didn’t fix the problem, though loading screens are dramatically quicker now 
System: i7, Mobility Radeon 5800 series, 8G RAM. Graphics are at the recommended settings (no AA, no vsync - even though my rig usually has no trouble with either).
Any ideas would be great. Cheers.
