Ok, just heard from @jonshiring. His words are 'Let's break it', so the plan is to make the beta fully open and have you max stress it!

In its current form, it's difficult to understand Titanfall's resolution choice considering the variable performance. As it renders at 792p, The game relies on the Xbox One's scaler to output at 1080p. Now, we've just updated our Xbox One to the latest system software and the good news is that the harsh edge-enhancement has completely gone. We'll be looking at the improved scaler in a little more depth very soon, but while the situation is clearly an improvement on the preview code we saw previously, there's still a good deal of aliasing to contend with. It appears that Respawn is caught between a rock and a hard place with regards image quality vs. performance.

Frame-rate hit or not, trundling forward in a Titan still kicks off the most spectacular moments possible in the game. The animation for loading into a cockpit is a show-stopper, and details like having each window pane rendered individually before meeting in the centre are complex touches that surprisingly don't stretch the frame-rate. Certainly, most alpha effects from missiles look plain in isolation, but in their numbers, and in concert with lengthy smoke trails and spark particles, you can convincingly create a maelstrom of elements that still looks impressive.
