120 Hz ProMotion Display Benefits
The 6.9-inch LTPO Super Retina XDR display isn't just bigger—it's smarter. ProMotion dynamically adjusts between 1Hz-120Hz, hitting 2,500 nits peak brightness with 10-bit HDR support. That 240Hz touch sampling rate? You'll feel the difference when you're trying to nail those quick-scope headshots.
But here's something Apple doesn't advertise: there's a persistent bug affecting iPhone 13-15 Pro models where selecting 120 FPS actually results in performance worse than 90 FPS settings. The game feels choppy because ProMotion isn't being correctly instructed to run at maximum refresh rate. Frustrating? Absolutely. Fixable? Keep reading.
Thermal Design for Gaming
This is where the iPhone 17 Pro Max really shines. The Dual Vapour Chamber Cooling System is 50% larger than the iPhone 16 Pro Max—and trust me, you'll appreciate this during those intense final circles. Graphene-based Thermal Interface Material improves heat conduction, while iOS 18's AI-controlled thermal throttling intelligently adjusts performance instead of just slamming the brakes.
Real-world result? 92% peak performance maintained after two hours of gaming, with surface temperatures staying under 40°C. That's impressive for any mobile device, let alone one pushing 120 FPS.
Essential PUBG Mobile Settings Configuration
Graphics Quality Settings
Forget the preset quality levels—they're not optimized for competitive play. Here's what actually works:
Render Scale: 100%
FPP Field of View: 103
Overall Graphics Quality: Custom (always)
Anti-aliasing: Ultra
Post-processing: High
Shadows: Low (this improves enemy visibility significantly)
Textures: Ultra
View Distance: High
Why shadows on low? Because competitive advantage trumps pretty graphics every time. You'll spot enemies hiding behind cover much easier.
Frame Rate Selection and Bug Workarounds
Remember that ProMotion bug I mentioned? Here are two community-discovered workarounds that actually work:
Screen Recording Method: Set graphics to 120 FPS, activate iPhone's screen recording, and keep it active throughout your match. This forces the display to render at maximum refresh rate.
Accessibility Setting Method: This one's a bit more involved, but it's more reliable. Set frame rate to 120 FPS, then navigate to Settings > Accessibility > Motion and activate 'LIMIT FRAME RATE'. Enter the game briefly, exit, disable 'LIMIT FRAME RATE', then relaunch. Sounds weird, but it works.
iOS System Optimization for Gaming
Pro Gaming Mode Activation
iOS 18's 'Pro Gaming Mode' is a hidden gem that dedicates 90% of CPU/GPU resources to your active game. It mutes notifications, pauses background tasks—basically turns your iPhone into a dedicated gaming machine.
Here's how to activate it: Settings > Game Center > Enable 'Pro Gaming Mode' > Configure automatic activation for PUBG Mobile > Set maximum performance resource allocation. The system supports Metal 3 API for ray tracing, mesh shading, and variable-rate rendering.
Background App Management
This might seem obvious, but you'd be surprised how many players skip this step. Force close unnecessary apps before launching PUBG Mobile. Disable Background App Refresh for non-essential applications. Turn off automatic downloads and updates during gaming sessions. Disable location services for apps that don't need real-time data.
Every bit of system resources matters when you're pushing 120 FPS.
Advanced Performance Tweaks
Memory Management Optimization
The enhanced memory architecture requires specific optimization. Restart your device before extended gaming sessions—seriously, this makes a difference. Clear Safari cache and cookies, remove recently deleted photos and videos, and temporarily offload unused apps.
