--- Comment #6 from Paul Gofman gofmanp@gmail.com --- FWIW I tried that on demo d3d8 version (without community tool), and it fixes the similar issue. I tested the very start only. The demo version was spamming FIXME messages from process_vertices() previously (was unable to lock the buffer) and was not drawing fire around the crashed helicopter, now it is fixed.
