I saw a few suspicious things yesterday that looked a lot like wallhack to me. Pre-firing around corners at people 50m away without a drone in the air. Kill streaks flicking DSR shots through smoke at people they couldn't have seen. Low level account naturally.
Didn't look like netcode issues, but could have been dumb luck or intuition.
Its called desyncs.
As I said in my post. It didn't look like netcode issues. And desync doesn't account for players flicking to opponents they could not possibly have seen or heard.
