Here's the scenario. I installed Ubuntu 64 bit on my sisters Quad (4) Intel computer with 4 gigs of ram. It runs 0 A.D. perfectly. When I look at System Monitor, all 4 of her processor chips are working together while the game is running. My computer at home has Ubuntu 32 bit installed on an Intel Core 2 Duo with 4 gigs of ram. When I run 0 A.D. on it, the mouse cursor is choppy, making the game unplayable to me. When I look at System Monitor, one of my two processors if working near 100% while the second processor is running at around 5% while 0 A.D. is running. Interesting enough, all other emulation games I play, both of my processor chips are sharing the work. I am considering upgrading to a 64 bit of Ubuntu Linux if those here think that would help me run 0 A.D. smoothly. There is debate in the Linux community on whether or not 64 bit installations really help at this point. Perhaps it would help with 0 A.D. ? Please reply and comment.
