On the subjsect of input lag i found this on gamasutra http://www.gamasutra.com/view/feature/3725/measuring_responsiveness_in_video_.php?print=1
Just a snippit from article
Theres also a good article linked http://www.gamasutra.com/view/feature/1942/programming_responsiveness.php about game input lag.

I tested various other games, with various results. I'll list the results in 60ths of a second, and the results have been adjusted -2 to account for the plasma lag. All games are on the PS3 unless noted otherwise, and I've included the PS3 system menus and GTAIV for reference.
Games that run at 60 fps:
* PS3 System menus: 3/60ths
* Guitar Hero III (Xbox 360): 3/60th
* Ridge Racer 7: 4/60ths
* Virtua Tennis 3: 4/60ths
* Ninja Gaiden Sigma: 4/60ths
* PixelJunk Racers: 4/60ths
Games that run at 30 fps:
* Genji: Days of the Blade: 6/60ths
* Tony Hawk's Proving Ground: 8/60ths
* BlackSite: Area 51: 8/60ths
* Halo 3 (Xbox 360) : 8-10/60ths
* Skate: 10/60ths
* GTAIV: 10/60ths
* Harry Potter and the Order of the Phoenix: 10-14/60ths
* Heavenly Sword: 7-18/60ths
The first question that arises is: why are there no PS3 games with a response time of 3/60ths? The PS3 UI runs at 3/60ths response time, so it's quite possible. Why do all the 60fps games run at 4/60ths?
Still, that's still pretty good, and those games all feel quite responsive. Guitar Hero III on the Xbox 360 manages a very impressive 3/60ths - very important for that type of game, especially when it's actually 5/60ths on many TVs.
Next, why so much variance between the 30fps games - ranging from 6/60ths to 18/60ths?
It's worth noting that while EA's Skate seems like it would be a bit sluggish at 10/60ths, it actually feels quite responsive, in large part due to its use of stick gestures for input, as the movement starts before the gesture is complete, yet the player mentally synchronizes it with the end of the gesture, and so it actually seems very responsive.
