Checking a New Gaming Setup
Seven checks that confirm you are actually getting the performance you paid for, rather than assuming it.
Gaming hardware is unusually easy to buy and then silently under-use. A high-refresh monitor left at the operating system default runs at 60Hz. A high-polling mouse connected through the wrong port reports at a fraction of its rate. A keyboard advertised for gaming may still drop keys in exactly the combinations games use. Each of these is invisible — the equipment works, it simply is not delivering what you paid for, and nothing warns you.
The theme running through this checklist is the difference between capability and configuration. Almost every step below distinguishes what your hardware can do from what it is currently doing. That distinction is where most of the disappointment in new gaming setups comes from, and it is nearly always fixable in software once you know to look.
The controller steps matter for a different reason. Analog sticks are the only component in the chain with a continuously moving electrical contact, so they wear faster than anything else you own, and a brand-new controller can occasionally arrive with measurable drift. Testing on day one both catches a genuine defect while it is trivially returnable and gives you a baseline reading to compare against in a year.
