Frames Are A Budget. Spend Them Well
Start a performance investigation by finding the bottleneck, then measure the effect of one change. At 60fps the frame budget is about 16.6ms. These guides explain how to inspect that time and use asset checks to find work worth investigating.
Don't Optimise Blind
Never change code, settings, or content before confirming which thread and system is the actual bottleneck. Fixing the wrong subsystem wastes time and can make the real problem worse. Measure, change one thing, measure again.
