Request for examples of player issues with netcode.

Hello,

My PC is too weak for me to record videos while playing, but I can precisely describe what happened once.

My internet connection never had any issue, in FPS games or in any other usages, so the network smoothing factor was set to 0.

What happened:

  1/ Waiting behind a corner where this was enemy-crowded behind, I fragged a first enemy poping out

  2/ For the 3 others I fragged in a row, the hit marker was blinking fast for about 0.5 seconds, before they poped out the corner

  3/ Consequently, this was usable as a wallhack: as soon as I was seeing the hit marker blinking (I was not shooting at all at this moment), I was very aware of the enemy about to come in, so I could start shooting in a predictive way

  4/ Indeed, all those 3 enemies came out exactly a few milliseconds after the strange hit marker was blinking for no reason: the behavior was consistent

Regarding the main issue of the thread, I never met an "untouchable" enemy. Very often (every 2 minutes), I get like 0.5-2 seconds hangs (with sound loops meanwhile), that I didn't meet in BF3. This is probably due to 64b playing on Dual Core (CPU lag or so), but it may also be a network-retaining-data reason. When this occurs, I get hands off keyboard and mouse, to help spike recovery (not stacking more movement or any action on the overflown CPU). My PC resources are clean when launching the game: antivirus or any other listener process is closed, all useless apps or Windows services too: just origin (the hanging lady), 1 firefox window/tab for battlelog, and bf4.exe.

In the end, I'm not sure those issues are related to the netcode, but maybe of intense CPU usage spikes on the "untouchable" player side, making him network-underflowed or something alike, for he spike-recovery period on his PC.
