Annoying Green Smoke

[Bikerjack]

I know this subject has been discussed before but I wondered if anyone has a definitive fix for this annoying problem?

The only way I can stop it occuring in Multiplayer is by starting a Single player mission first and then exiting after a few minutes and then going into Multiplayer and connecting to a server. If I go in direct the green smoke is always there - sometimes I forget to do this, especially when clearing the cache at the end of one mission before rejoining the server for a new mission.

This happens regardless of the AA settings - Multi sample or Super sample in ATI Catalyst.

Is this unique to AMD cards or does it also occur with Nvidia GPUs?

Why?
