I will say that the initial feeling loading in felt pretty good, especially in Social (like 120-144FPS) then again it could be because of only 5 people in the district. I personally found the new colors/textures and lighting (when it worked properly) made San Paro become more lively and actually feel like a city. Coupled with the view distance, my opinion is that APB 2.1 is visually a lot more appealing than APB 1.2. On that same note, perhaps because it's not completely finished, the difference visually between Ultra and High/Medium seemed negligible.
EDIT: was able to play about an hour worth of 2v2/3v3 missions, and I'll be honest it felt pretty nice; It didn't feel much different than live and things were pretty enjoyable. The lighting on where buildings connected to the ground was super janky and looked really off.
The performance however, on anything beside Low/Minimal is, in the nicest way possible...a big yikes as the cool kids would say. Driving around Waterfront on Ultra yielded about ~40fps average. Now I know we were asked to leave the fps out of it but it's a bit difficult to measure the feel of a game when it's a slideshow. The inventory UI results in huge FPS drops and stutters when trying to do just about...anything. Suffice to say the laggy and stuttery UI does not help the feel of APB 2.1. Aside from all the negative issues above, the mid-tier FPS that most players are used to (70-100) felt smoother than live, I assume this is from the engine itself.
EDIT: Played about an hour in a 4/4 Financial district so I was able to play a few missions, settings were default medium and changed view and foliage distance to far: I would average my FPS around ~130. Waterfront still ran like poo.
Also not sure if it's been addressed but perhaps really dark symbols don't get copied over correctly? Example of my go-to symbol on both live and 2.1 in the same spot. Turning up the brightness on 2.1 didn't seem to affect the symbol.
LO's work is not going unnoticed, you guys were left with ground zero of a nuclear blast and only given a couple plastic bags to clean it all up. Your hard work is appreciated and I am hopeful for APB's future. Like many other people have said: The performance is a necessity in order for this grand engine upgrade to be successful for APB, otherwise we've got a huge problem on our hands.
