Overall the frame rate is fairly consistent on x1. I would be lying if I said it never dipped, I'm sure I've caught a moment of dipping at least once. But overall very playable.
Yes I experienced a significant dip at least once Like you say it's fine though.
I'm addicted all over again pretty much.
From what I can vaguely remember of the alpha, the upgrade to 1080P isn't all that big an improvement. But still nice I'm sure.
It took me maybe 4-5 hours to download the 18GB on a 15mbps connection. I used to have 30 mbps and well, that obviously woulda been faster. Anyways, even 18 GB takes a long time. And there's no playing while downloading, it made me wait til 100%.
I did have an odd glitch though, the audio was completely missing a few times after initial download. Only on Destiny, the dashboard still had sounds. And it sometimes happened again after going to dash. I did a hard restart though, that seemed to help a lot, although it still did it once more since then.
I did the buy 360 get X1 thing though, and it went flawless and immediate. The first time I switched to X1 and tried to DL that version it said "unavailable", but within like 10 seconds it had switched to "free". I understand PS3 people who digitally pre-ordered have problems.
