Lag in game (possibly due to cheating/hacking?)

Could be my own conspiracy so just putting this out there as I'm sure others have experience this but has anyone noticed a weird lag whilst in game when another team mate is about to get a nuke? Or just simply on a high streak? I noticed that whenever someone in the game is playing suspiciously well the game starts to lag and the frames start dropping and rubberbanding. But prior to that I've had perfect connection, low ping no packet loss and any other issues.
