I'm in the same boat with my Denon AVR-989 and VT-25. You can only pass through HDMI 1.3. For 3D, you need a receiver that is HDMI 1.4 compliant.

To play that game in 3D, the best way is to connect the ps3 to your TV directly and send the audio to your receiver via optical cable. It is stunning in 3D!
