So if the box is low on ram, the HL2 core will memory it's not actively using right that moment? I think I now understand what the issue is, although I'm confused by the use of scope locking for something like this.
In any case I've added MDLCACHE_CRITICAL_SECTION per Jay's instruction, and the result is several dozen fixes, added to the KI list: http://developer.valvesoftware.com/wiki/SDK_Known_Issues_List#IsFrameLocking_assert Confirmation from Valve would be appreciated that this is correct with respect to the way the closed-source core works. -bk At 2006/08/30 09:02 PM, Jay Stelly wrote: >Since there are no explicit unlock operations on the studio headers we >use a concept we call "frame locking" where they are guaranteed to >remain in memory (i.e. not get flushed for some other memory allocation >request) as long as the frame is in scope.
