Rainbow Six: Vegas: A Performance Analysis
 

Rainbow Six: Vegas (RSV). We'll be talking a little about the game and how it performs, and we're especially interested in it because it's one of the first games out now based on Unreal Engine 3.

Thankfully with Rainbow Six: Vegas, we found we didn't run into nearly as many of the problems and annoyances we did with Double Agent, and for the most part the game seems like a much more solid port of the Xbox 360 version, if this is in fact the case. It isn't perfect, however, and there are some issues that still should have been fixed before the game's release, but we'll talk about these later on.
