You said a sub 720p compressed image laggy game looked and played amazing.
And no, those images aren't compressed. GOW was and you thought it looked great.
If you can't see a difference in those screens you absolutely can not on a TV in motion
1) It wasn't laggy when I played (andI expected it to be). It was VERY playable. I had more issues with gameshare with Dboy than PSNow
2) Yes the image is compressed, the image itself describes the resolution of it.

3) Of course you can tell the difference on a larger viewing surfare. That's where you REALLY tell!
