Howdy,
I did this course last year. The hardware module was fairly tough and a lot of people only took in order to do the real-time rendering as that seemed like a really cool module, which it was =]. However, the hardware module was that tough that a few people avoided it at the expense of missing out on the later semester module (real-time rendering).
As the other poster said, be prepared to read a lot of technical papers on console/PC architecture. You also get giving a paper to review which you have to give a summarized version of the chosen paper. Very tough if you have little or no experience with computer architecture. Prepare to be bombarded with "Memory Latency" talk, I will take that word to my grave =/. ha.
I ended up doing that module and its paired real-time rendering module. Also done: AI, Autonmous Agents, real-time animation and real-time physics. It must be noted that when I did AI, the module seemed to be all over the place, we did like 6 weeks of "Natural Language Generation" and 6 weeks of AI algorithms. The NLG part seemed to be tacked on or something just seemed like they threw the thing together at the last minute cause a lecturer pulled out or something. In the end it was a bit of mess and we all ended up being giving assignments all the way through christmas. However, I hear that this module has been revised for this year, so you should be grand for next year.
The augmented reality module, looked really cool. Some of the games the lads created were class and it was a module that I kinda wished I did so keep that in mind.
