Lag is the most common problem users face. It can make games slow, stuttery, or unplayable.

Top Ways to Fix Lag

1. Use Recommended Graphics Backend

3. Enable Fast Memory

   • Settings → System → Fast Memory (unstable) → ON

4. Enable Multithreading

   • Settings → System → Enable Multithreaded Rendering → ON

5. Use Frameskip

   • Settings → System → Frameskip = 1 (helps older devices)

✅ These steps often increase FPS dramatically on all games including GTA 5, Tekken 6, and God of War.
