1. Fix the rendering issue. Players that pick up a weapon they've not picked up before, get lag and frame drop at the same time. This also happens if you, yourself switches between a bag that you haven't used in the match. Frame drops are also caused in just regular firefights, unsure why it occurs.
I'm not sure if the rendering issue causes the next round to glitch as well. This is a print screen showing how every round loads.: 
(Lock frames, such as 30fps, 60 fps etc... I'm not sure if this suggestions is necessary, and i'm not sure if this would help to solve the rendering issue. But if this lock frame option can remove or at least decrease the rendering issue, then it might be a solution. But the round loading isn't because of the frame drop, it's the servers fault there. Everyone experiences it.)
2. This needs a fix. We all are aware of the 20_0 error code. But i just wanna put it out there. The 20_0 error code seem to affect mostly the Global Risk team. I've so far not gotten any error codes on Black list, but as soon as i play on Global Risk. Most of the team gets errors, some of them are lucky enough to avoid it.
You can sorta predict whether a person is gonna get this error code. Because when ever the new round is loading, the characters are freely floating around with a weird body pose. And when that happens, at least 1 or more gets error.
3. Crouching at this spray i placed, kills you
.
4. Biohazard ADV mode on broken station, shooting jumping Super Disasters & spark moles makes them teleport to your location. Wait for them to land on the surface to avoid this bug.
The ping to the servers is fine. In rare moments you get a huge lag spikes, but it's mostly stable. There's still an issue with the server and net coding etc.... I hope you guys get this resolved soon or later. No pressure, but i really wanna play Crossfire and enjoy the experience.
