I play on a 2012 MacBook Air, and I get this error message pop up every 5-10 minutes when I play Bullet on chess.com. I get it in both Safari and Chrome. It also shows up on Lichess when using the analysis tool after 20+ moves in depth.
1) Is this issue affecting my performance? It’s hard to know if I’m actually playing slower that it feels or if it’s a graphics issue because my laptop is old and doesn’t have enough processing power.
2) What’s a good MacBook with enough power (CPU/GPU cores, RAM, etc.) to handle all the energy and memory Chess.com & Lichess require for performance.
