I tired running my system with one CPU, which the problem still occurred. Then still with one CPU I reniced the steam.exe and hf2.exe processes to -10, this still would freeze. A renice to -15 appeared to be stable and ran for several hours without a problem. I'm about to test with two CPUs and renice -15.
2 CPUs is okay, although I forgot to add that I run with -dxlevel=80 and with the renice.
