Redditor mertbaris01 successfully ran Grand Theft Auto V on an iPhone 17 Pro Max using the XeniOS Xbox 360 emulator.
The emulation operated at a resolution of 1280 x 720. During testing, the iPhone 17 Pro Max experienced overheating.
Average framerate achieved during GTA 5 emulation
While the game achieved an average of 19-20 FPS, the framerate dipped to 12 FPS during helicopter exploration within the city. Omar Sohail stated that the experience on the iPhone 17 Pro Max was not enjoyable.
Hardware and optimization factors
The performance issues in the GTA 5 emulation are attributed to the optimization level of the XeniOS emulator rather than shortcomings of the A19 Pro chip. The iPhone 17 Pro and iPhone 17 Pro Max are equipped with the A19 Pro chip and a vapor chamber cooling system.
Maximum performance increase of A19 Pro over A18 Pro and A17 Pro
The A19 Pro chip used in the iPhone 17 Pro and iPhone 17 Pro Max can achieve up to a 69 percent performance improvement over the A18 Pro and A17 Pro. Looking forward, the upcoming iPhone 18 Pro and iPhone 18 Pro Max are expected to feature the A20 Pro chip.
