The top shots are a level from UT3 I'm sure (and the others look like UT maps also).
Are these tests showing the same maps on both builds of the engine? I'm sure Gears 3 will be a jump over Gears 2 but I'm not we can judge much from shots of UT MP levels designed for FPS play vs levels build for Gears TPS play.
Try to be reasonable... its easier than you think...
