Jericho Framerate Issues!

I got the demo, played it on my 1080p 50" but it got jaggy n startered to stutter, then i looked up its resolution on the internet, and it says its 720p, i set my ps3 to 720p and it worked fine.

Is this the same issue as R6V?

should i set every game to its original resolution instead of rendering it?

If a game sends a 1080p signal, that means that it does indeed support it, all games automatically set themself up accordingly to what resulotion you have chosen for your system aswell as what the game itself supports.

I ran it in both 1080p and 720p and it made no difference what so ever as far as framerate goes...
