Yes alm ost all homebrew apps has this option and its wonderful but it was never possible on retail games until now. The dev should be giving a huge award of some sort for this cause this one the most useful apps Ive seen come out for the xbox IMO. I mean I never turn on the flicker filter in anyting, just try and play doom with the flciker filter on 5 and then put it on 0 and you'll see the difference.
I used it and it works on every game I throw at it. Although DOA 3 seem to look ugly and tons jaggies with it. This is greatly appreciated. Thank you sir!
Now if some one can only code this into xbmc so I can do it on the fly.....
