Have noticed significant performance issues during the stress tests marked by constant and significant frame drops and subsequent stuttering of frames while looking into Zelenogorsk (stress test town) or by moving character left to right or right to left in a sweeping motion.
Thoughts. Possibly caused by both the number of players and the sounds of the gunshots all concentrated into small area.
This issue has been present during the last couple of stress tests. If I move my character away from the stress test area frames generally improve until stable.
I have tested this at various in game video settings from poor to extreme which have not affected the issue. Frames can suddenly drop 30-40 fps at a time and then recover with other sudden drops of 10-15 FPS at times which produces an overall jagged performance. I have also tested this with both V-sync on an off.
Away from the stress test area with extreme settings i generally get 115fps and in the stress test area it is jumping all over from 30-60fps.

This issue is not present in offline mode other than the occasional FPS drops here and there.
