BO1 Zombies: performance & optimization FAQ
How should I compare performance across Zombies maps?
Start with one map in the selector and repeat the same opening round. Let its assets finish loading before judging frame rate. A different map or a later, busier round changes the workload, so it is a poor comparison for a browser-setting change.
What browser checks should I try for BO1 Zombies?
Keep the game tab visible and pause other games or video. If Chrome Energy Saver is active, compare with it off while plugged in; restore it if there is no benefit. Change one thing at a time and repeat the same scene. Export any available save backup before clearing site data or switching browser profiles.
