Well, I've finally finished downloading 3.0 and it actually runs better than I would have thought after reading all the posts from closed PTU players. The main problem for my system seems to be twofold, one problem is that the system can't stream data fast enough, due to me having installed the game on my 2 TB Storage HDD, a Samsung HD204UI, instead of a SSD, so I get small freezes when the game has to wait for the datastream to catch up and two beeing that my vidcard simply doesn't have enough Vram. My current system looks like this: i7 2600 on a H67 mainboard with 16 Gigs of ram, a GTX 670 with 2 Gig of VRam, running win10 on my 120 Gig SSD and everything else from the mentioned Samsung HD204UI HDD. It runs actually quite acceptable in arenacomander but then it also doesn't have to stream that much data in that mode. I'm getting a constant 30-35 FPS in Arenacomander even with lots going on and, if I leav my toon standing around for a bit so that the game can cache enough data, I get around 15-20 fps on crusader. That is until the game runs out of data and has to stream new stuff from my disk wich sends performance down the crapper. So having a fast SSD, preferably a PCI-E SSD, should help imensly to reduce stuttering caused by caching and also vidcard with 4 gig or more VRam seems to be absolutely the lowest one should use.
Edit: Also one thing that I foun d to be kinda anoying is the two speeds that the chararcter can move in. You can basically either walk around insanely slow or run around like an idiot. It would be really nice if there was some sort of fast walking speed avaliable.
