OnePlus 12 officially supports PUBG Mobile's 120 FPS Ultra Extreme mode (version 3.2+), requiring Smooth graphics settings. Snapdragon 8 Gen 3 delivers stable performance with thermal control below 37.8°C.
OnePlus 12 Gaming Specs and PUBG Mobile Compatibility
Here's the thing about the OnePlus 12 – it's basically built for this exact scenario. The Snapdragon 8 Gen 3 chipset doesn't just support PUBG Mobile's 120 FPS mode; it absolutely crushes it with a 30% CPU performance boost and 25% GPU improvement over the previous Gen 2.
That Adreno 750 GPU? It handles 120 FPS rendering like it's barely breaking a sweat. I've been testing Call of Duty Mobile benchmarks, and we're seeing a consistent median 120 FPS over 30-minute sessions while using only 12% CPU and 65% GPU capacity. That's impressive headroom.
You'll want to dig into your battery settings and enable High Performance Mode – this removes those annoying software limitations that manufacturers love to slap on for battery optimization. Trust me, you want maximum CPU/GPU capacity unlocked.
The LPDDR5X RAM prevents those frustrating frame drops right when you're in the middle of a firefight, while UFS 4.0 storage means your assets actually load when they're supposed to. And here's a neat touch – Aqua Touch keeps your screen responsive even with wet fingers, which is clutch if you're one of those intense claw grip players who gets sweaty palms during ranked matches.

Enabling 120 FPS in PUBG Mobile: Step-by-Step Guide
PUBG Mobile version 3.2+ finally brought us what we've been waiting for – proper 120 FPS support. The device compatibility list is still pretty exclusive: OnePlus 12, OnePlus 11, Samsung Galaxy S24 Ultra, iPhone 15 Pro Max, and ASUS ROG Phone 8 Ultimate.
Here's how to actually get it working:
Update PUBG Mobile to version 3.2+ (seriously, check this first)
Navigate to Settings > Graphics & Audio
Set Frame Rate to Ultra Extreme – that's your 120 FPS setting
Max out that FPS slider
Double-check that graphics quality is set to Smooth
The Ultra Extreme tier sits above the traditional Extreme (60 FPS) and 90 FPS options. Don't forget to activate OnePlus Gaming Mode – it prioritizes system resources and blocks those annoying notifications that always seem to pop up at the worst possible moment.
Smooth+Ultra Extreme Settings Breakdown
Let's be real about what you're getting here. The 120 FPS Ultra Extreme mode only works with Smooth graphics settings. You're trading visual fidelity for pure performance – and honestly? That's exactly what competitive players want.
My testing shows 120 FPS with Smooth graphics actually uses 65% GPU compared to 61% for 60 FPS with Max graphics. Counterintuitive, right? But that's the reality of pushing double the frames.
Here's the performance hierarchy that actually matters:
Smooth + Ultra Extreme (120 FPS): Maximum responsiveness, minimal eye candy
Balanced + Extreme (60 FPS): Decent visuals, standard competitive performance
HD + High (30-60 FPS): Enhanced visuals for casual gaming
Ultra HD + Medium (30 FPS): Maximum visual quality, basically cinematic mode
Pro players consistently choose 120 FPS for smoother target tracking, reduced input lag, and those split-second advantages that win matches.
Thermal Management and Performance Optimization
OnePlus 12's thermal management is genuinely impressive. External temperatures stay below 37.8°C during 120 FPS gaming sessions – I've verified this across multiple extended tests. During a brutal 70-minute Genshin Impact session at maximum graphics, the phone sustained 35°C external temperature without any throttling.
The vapor chamber cooling system and thermal algorithms distribute heat efficiently across the internal structure. But here's what you need to know for real-world gaming:
Critical thermal practices:
Never game while charging (seriously, don't do this)
Remove thick cases during extended sessions
Only enable High Performance Mode when you actually need it
Keep an eye on those built-in thermal indicators
External USB-C cooling accessories with semiconductor cooling and active fans provide additional thermal management. The advanced models even integrate L1R1/L2R2 triggers for six-finger operation while keeping things cool.

Real-World Performance Benchmarks
Call of Duty Mobile achieves 83% frame stability over 30-minute 120 FPS sessions. PUBG Mobile maintains similar consistency under Smooth+Ultra Extreme settings. Those lower stability percentages you might see? They're usually reflecting 30 FPS menu caps rather than actual gameplay performance issues.
Here's what the numbers actually look like:
120 FPS Mode: 83% stability, 12% max CPU, 65% max GPU
60 FPS Mode: 84% stability, 9% max CPU, 61% max GPU
That 5400mAh battery gives you 4-5 hours of continuous 120 FPS gaming versus 6-7 hours at 60 FPS. Extended sessions maintain consistent thermal performance without throttling – I've tested back-to-back gaming periods and the performance stays rock solid.
Advanced OnePlus 12 Gaming Features
Hyper HDR actually improves contrast and visibility in challenging lighting situations, while Hyper Resolution provides sharpening filters for enhanced clarity. Game Space offers centralized optimization including performance monitoring, notification blocking, and network prioritization with automatic PUBG Mobile detection.
The built-in network optimization reduces latency and packet loss by prioritizing game traffic while limiting background app bandwidth usage. There's also Frame Interpolation that attempts 60-to-120 FPS upscaling through artificial frame generation – though I'll be honest, its effectiveness remains questionable based on standard FPS measurement tools.
Troubleshooting Common Performance Issues
Frame drops driving you crazy? Close background apps that are hogging resources, let the phone cool between sessions, verify your internet connection is stable, and make sure you're running current software versions.
Overheating becoming an issue? Game in air-conditioned environments when possible, remove cases during extended play, avoid direct sunlight, and take cooling breaks. Your phone (and your performance) will thank you.
Optimize performance by clearing cache data regularly, restarting your device before serious gaming sessions, and ensuring you have adequate storage for those temporary files that accumulate during gameplay.
Competitive Gaming Setup and Accessories
Professional competition demands the right gear. USB-C powered cooling fans with trigger attachments, anti-glare screen protectors, ergonomic gaming grips for comfort, and high-quality headphones for audio advantage. OnePlus 12's 5G capabilities and Wi-Fi 7 support provide optimal network performance for reduced lag.
Bluetooth controller support is available, though competitive players consistently prefer optimized touch controls with external triggers for maximum responsiveness.
Maintenance and Long-term Performance
Weekly maintenance should include cache clearing, storage optimization, and software updates. Monthly deep cleaning might require a factory reset if performance has degraded significantly, though this is rarely necessary with proper care.
Monitor OxygenOS update release notes for gaming-specific optimizations that enhance PUBG Mobile's 120 FPS experience. These updates often include thermal management improvements and performance tweaks.
Protect your gaming longevity through careful thermal management, avoiding extreme temperatures, and using quality charging accessories that prevent electrical stress on components.
