Fun thread. Shift, PGR 4 or GT5. What has better graphics.

[haxxiy]

PGR4: 30 frames per second, 1280x720 (it may be actually 1024x600 like PGR3) and 2xFSAA
GT5P: 60 frames per second, 1280x1080, 2xMSAA gameplay, 4xMSAA on replays, 1920x1080 and no AA on menus.
Forza 2: 1280x720, 60 frames per second (30 on replay due to additional screen effects)
Thus,
GT5P > Forza 2 > PGR4
In my opinion.
