Been playing for a few hours now and I haven't run into any problems. I disabled anything I could get my hands on ("r_skippostprocessing 1" will give you a huge boost in framerate, scratch that, won't work online D: ) and it's running well above 60 on a Geforce 275 with a AMD 720x3. No connection issues no nothing, ping seems alright but it really sucks that you can't view it in-game, bars tell me nothing, get that console shit out of here.
And this FOV bug is killing me, playing with 70 is unbearable but I can't sprint with anything else, seems like SD is working on it though.
That said the game seems to be alright from what I gather, I tried all the guns and found a few that stuck with me, but I don't wanna use SMGs until I get the light body. Revolver is frickin' sweet! I feel like going all out soldier but with no one actually doing objectives (and the maps being rather confusing starting out) its mostly just a glorified TDM at the moment, haven't had a single good team game yet. And the maps can feel a bit empty at times even on a full server. But this will change once people start getting good/I find a good server.
One thing that I really, really don't like is the sensitivity when using the sights, I try not to because the difference is so jarring. Even with the "adjusted sights" it feels like crap, I hope they'll let us tweak that in the future, unless there's a console command I'm missing?
Verdict so far, feels nice and smooth! A few minor fixes needed.
*Oh and with this "look at dude to buff him" shenanigans EVERYONE looks like a spy.
