I would like to add this info but no I am not including a movie.
I had been playing on an older PC, quad core with GTX8800, XP with 3 gigs of ram. Game ran fine, got up to 28 fps in normal areas, WZ would become a problem when everyone kinda piled into a big fight and it would drop to only a few fps but I was able to play though it most of the time. I finally started fighting on lium and when their would great big fights the fps dropped to pretty much nothing but I would just spam tracer and hope for the best. Since I was playing Imps I would survive the fight most of the time and get points so whatever I thought.
However I got bonus from work could of weeks ago, so I bought myself a really nice PC, 6 core 4.3 processors, dual 580 vid cards, 16gigs of ram and thinking ok reps look out I can fight you now.
And it is true in a fight when lium is full, when all the aoes are flashing I get about 20fps give or take. Its enough for me to fight very well but still seems pretty lame imo
Another thing I noticed is that anytime I join an ops group there, the lag is really bad specially when a base is captured, even when not in an ops group their is a lag spike for a second during the announcement. So I don't join ops groups for that reason.
In wz now I do not have any problems but still the fps is about 30 at best. However, everyday at least twice, the game just locks up the pc and I have to hard boot it. I set it to run as XP and that seems to have helped a little but I am not sure.
I have played a lot of mmo's and my feelings is this engine is not to good for mass pvp.
