01.Why does LoL crash on good PCs?
League of Legends is a game much more dependent on the single-core CPU than on the graphics card. This means that even with an RTX 4090, if Windows is occupying the main processor core with telemetry or Windows Update, LoL will suffer drops.
The Riot Client is known to consume excessive RAM in the background even when you are in a match. Monitoring and managing this process is essential to keep the match fluid during team fights.
Critical Setting: Timer Resolution
Windows 11 uses a 15.6ms timer to schedule processes. Reducing the Timer Resolution to 0.5ms ensures that the scheduler delivers CPU cycles to LoL much more frequently, reducing frametime spikes that cause visual stutter.
