Three Windows utilities for gaming setups, plus practical guides and articles about PC gaming.
Windows utilities for gaming setups
Jitsumi makes three Windows tools. Game Booster brings system readings, background-app controls, and maintenance tools together. Gaming Overlay opens app shortcuts and picture references over the desktop. Blue-Light Filter offers three tint strengths, a same-day schedule, and a temporary notes area.
