You probably know there is a griefers tool known as a graphics crasher. What you may not know is there is a defense. The blog The Green Lanterns has an article on how to defend against these crashers. See: Debug settings to make graphics crashers obsolete.
I have yet to try these settings. I have not been running into crash problems. So, you are on your own.
The The Green Lanterns site is mostly interested in griefers/anti-grifers and what they and the Lab is doing related to griefing. I have yet to decide if this is another vigilantly group or a responsible activist group. I tend to avoid griefer and anti-griefer discussions considering both sides mentally unhealthy. But, The Green Lanters blog seems oriented towards helping people, at least that’s my first take.
