@texre2@rkiefn You’re right to question that, but correct me if I’m wrong. He seems to play on laptop before this? If so then I recommend he checks for any defect cables and hardwares before jumping into niche topic like EMI.
@rkiefn This is entirely not true. If the electricity is really bad (bad wiring, grounding problems, big voltage drops, faulty PSU), it can affect performance.
