@mintnatteron Not too smart of me having - NOTEXTURESTREAMING in the launch command, but even finding that and removing it didn't solve the problem. Even did a clean reinstall and smoked the configs, still no joy.
What was the problem?
Windows 10 seems to fragment memory in a bad way. From a clean reboot, straight into Steam, launch Sandstorm, works like a charm. So the lesson from this hair-tearing excursion is do not try to use your computer as a normal desktop, then attempt to frag some bots, no workie. I should have remembered this from days of old, but I got so used to being able to run anything I wanted on this machine at any time.
Anyway, problem solved. Fun game. Glad I snagged a copy. Kudos to all the developers that made this one possible.
