Hello, I have started playing today, and have just been getting incredibly bad lag patches.
They occur whenever I'm not looking at the ground, and are horribly shaky and what-not.
I am running Version 7 of Unvanquished.
Mac OS X 10.7.1 Lion.
iMac 2011, AMD Radeon HD 6750M 512 MB Card installed, all drivers and updates are up-to-date.
It's 64-Bit, though some games have registered it as 32-Bit, though it runs like a 64-Bit anyways. (If that makes sense...)
Renderer is GL3.
Cheers, Amazonian1515
