a player name frogTheSecond showed up and had a bunch of exploits. thankfully he agreed to test them on the test server instead of the main one.

he was able to create multi-second lag, mesecons_debug didn't seem to throttle it much. probably these items should be mesemaker only.

QA

The GPU requires mesemaker now.

Still, the intial lag source is not be solved? And cannot be solved without disabling the functionality of the GPU?

What's the repro?
