The game still has a lot of issues with the game flagging innocent users for "invalid data" (aka cheating), often turning up with a ban. I had it flag for me for the first time a few days after launch, and just yesterday (with a new character, playing it since the flag was revoked about 1.5 weeks ago) it triggered the flag again despite still never cheating. On inquiring on how it could've triggered a second time (and offered to even send them my back-ups), I just received a pre-made message I got word-for-word a month ago.
Considering these flaggings can eventually lead to your online interactions being restricted and how rare it is off of PCs, you might be better off on console. They're getting better with handling it (lots of banned players were getting unbanned yesterday), but the system is still broken and it ultimately leaves the customer helpless for weeks without any instruction or indication of what happened (or when. It only scans twice a week) until things get done. They don't tell you what could pop up as a false positive besides telling you to disable all mods and programs interacting with the game, create back-ups, and to never pick up items from people you don't know (which doesn't help since some cheaters will change your stats on contact).
Regarding performance, it does chug a little, but I can get it running well with my GTX 660 Ti on low/medium settings. I had a 5 hour session without even a texture flicker. Still looks good, all things considered. It's not well optimized, but likely one of the more stable of their PC ports. Hard for me to judge as I'm playing with a RAM stick on it's last legs and I THINK the 660 Ti is just below minimum requirements.
