Problem in-game



I have a problem when playing in a low-grav server.

When i join the game i get about 2 mins of play time before the attached error occurs.

If anyone could help with this most annoying problem i would greatly appreciate it.

Note: as yet, i have not tested to see if this error occurs on regular gravity maps.

May be the map. Try playing in other maps and see if you get the problem. It says DX8, so maybe if you forced a dx9 via console on it, it might not happen (although expect a huge fps loss)


Thanks for the help guys.

Found out what was wrong.

Quote for Steam website:

Recently there have been some issues with Source engine games and certain Anti-Virus applications. These issues can cause game crashes and prevent the Steam Community overlay from functioning.

- AVG 7.5 and NOD32 have both been confirmed to cause crashes with Source engine games. Here are some examples of the symptoms you will see as a result of this issue:

1) A warning message telling you to reduce your screen resolution
2) A error message about failing to lock the vertex buffer
3) The game hanging with steam.exe at 100% utilization (or 50% utilization on a dual core, or 25% utilization on a quad core).
4) A hang while connecting to servers

If you are running either of these Anti-Virus programs then they need to be fully uninstalled.

- Kaspersky anti-virus can prevent the in-game overlay from working correctly. Kaspersky has provided a work-around that can be found here:
