Fix: inZOI Stuttering and Lags Badly

Fixing in-game lags or frame drop issues can be complex, depending on multiple factors.

This can resolve several issues in no time.

If you experience lags or frame drops while playing a game, it could be due to screen resolution, in-game texture resolution, shadow resolution, maximum frame rate, or the number of characters displayed.
