VSYNC needs to be improved, fps drops when it comes to custom objects, could've agreed if it's because of wooden pc but I feel the same when playing from my laptop which is having sufficient graphics to run battlefield at semi maxed settings but fail to run vcmp smoothly, whereas I remember playing this game smoothly even with my P4 machine back in 2011, but for now, it requires more than sufficient GPU usage and I guess you can do something about it.
Ping issues are there, F5 shows fake ping tbh, I've played 0.3 a few days back, my ping and rest pings were 200+ on F5 scoreboard, whereas when I joined 0.4 server, it shown somewhat 170-180 ping, dunno what is it, but 0.4 shows low ping than 0.3z used to show. If a guy is pinging 250 in 0.3z server, he pings 200 in 0.4, maybe update rate in 0.4 is decreased.
