With the games that enjoy vibrant communities still being updated with some frequency - unlucky DoD:S - the actual Source Engine itself is also receiving some spit and polish at the same time.

The latest update will see players in all the above games enjoy some optimisations for multi-core support and will see a potential crash - in the form of the heapsize error - removed altogether.

Also, following reports that some hackers were able to make it appear as if people had been VAC banned, that exploit has now been fixed putting an end to their "fun" and preventing any temporarily worrying moments for competitive players.

The changelog read:

Source Engine Changes (CS:S, DoD:S, TF2)

Optimizations to multi-core rendering

Removed -heapsize command line argument. Some detail: This command made sense in Half-Life 1’s memory manager. The current engine manages memory in a way that doesn’t need it specified. Under some circumstances, specifying a non-optimal heapsize causes crashes and/or reduced performance

Fixed an exploit that allowed people to send fake VAC messages to clients
