I spent almost a month chasing weird micro-stutters in CS2 matches, wiping display drivers and tweaking graphics settings without fixing the core problem. It turned out my aging power supply was struggling to deliver clean voltage during sharp load leaps when my hardware boosted. I cleared out a chunk of my unused inventory on DMarket to fund a new PSU, following the recommendations on https://textually.org/building-the-ultimate-counter-strike-gaming-rig/. Swapping to a quality unit with stable voltage regulation eliminated those annoying frame hitches instantly.
