Locked 120 FPS
Zero Touch Latency
Hardware Throttle Bypass
Apple's ProMotion display is capable of refreshing at 120Hz (8.33 milliseconds per frame). However, default iOS power governor profiles often throttle demanding games down to 60 FPS or 90 FPS after just 10 minutes of intense combat. Here is how iOSRED unlocks true 120 FPS.
1. The Science of the iOSRED 120 FPS Unlocker
The iOSRED Performance module directly interfaces with the Apple Metal graphics pipeline and CADisplayLink:
- Frame Target Overriding: Forces
preferredFrameRateRangeminimum and maximum values to a strict 120.0 Hz. - Thermal Governor Masking: Prevents iOS thermal dispatch daemons from dropping screen refresh rates during high-temperature sessions.
- Touch Sampling Synchronization: Synchronizes the 240Hz digitizer touch polling loop with display refresh intervals, cutting input latency in half.
2. Supported 120Hz Apple Devices
- iPhone Models: iPhone Duo, iPhone 17 Pro / Pro Max, iPhone 16 Pro / Pro Max, iPhone 15 Pro / Pro Max, iPhone 14 Pro / Pro Max, iPhone 13 Pro / Pro Max.
- iPad Models: iPad Pro M4 (all sizes), iPad Pro M2 / M1 (11" & 12.9"), iPad Pro 2020 / 2018 (120Hz ProMotion).
3. Recommended In-Game Settings for Locked 120 FPS
- Set In-Game Graphics Quality to Low or Medium (preserves GPU headroom for frame stability).
- Set Frame Rate to Ultra / 120 FPS in the game settings menu.
- Open the iOSRED floating HUD and toggle Native 120 FPS Unlocker: ON.
- Ensure iOS Low Power Mode is turned OFF in Settings > Battery.
