Frequently Asked Questions (FAQs)
1. Can I get 60 FPS on a 2GB RAM phone in PUBG Mobile?
No, 2GB RAM phones are limited to 30 FPS maximum in PUBG Mobile version 4.1. However, you can achieve stable 25-30 FPS using Smooth graphics, clearing cache weekly, and maintaining 20GB free storage. For 60 FPS, you need minimum 4GB RAM and Snapdragon 665 or better processor.
2. Does PUBG Mobile lag fix work without root?
Yes! All 10 settings in this guide work without root access. Developer Options are built into Android (unlock by tapping Build Number 7 times) and don’t require root. Avoid root-only lag fixes as they void warranty and risk account bans.
3. Why does PUBG Mobile lag in the final circle only?
Final circle lag occurs due to: (1) Multiple players rendering simultaneously, (2) Explosions and effects overloading GPU, (3) Device overheating after 20+ minutes of gameplay. Fix by playing in cool room, using external fan, and ensuring 20GB+ free storage.
4. What’s the best graphics setting for Snapdragon 665 devices?
Snapdragon 665 with 4GB RAM should use: Smooth + Extreme (60 FPS), Shadows OFF, Anti-Aliasing OFF. This achieves stable 40-60 FPS. For 3GB RAM, use Smooth + High (40 FPS) for consistent performance.
5. How to fix PUBG Mobile packet loss and high ping?
Fix packet loss by: (1) Using 5GHz WiFi band, (2) Playing during off-peak hours, (3) Disabling background data sync, (4) Selecting nearest server with <80ms ping, (5) Closing Netflix/YouTube on other devices. Wired connection via USB-C to Ethernet adapter provides best stability.
6. Should I use PUBG Mobile Lite or regular PUBG Mobile for low-end phones?
Use PUBG Mobile Lite if your device has 1-2GB RAM or if regular PUBG Mobile runs below 20 FPS after optimization. PUBG Mobile Lite runs at 40 FPS on 2GB RAM devices with only 600MB download size and maintains full gameplay experience with 60 players.
