StephenDev0, a Vapor developer, published the full benchmark on 27 September 2026. The benchmark confirmed that the PC version of GTA V operates at up to 80 frames per second on an iPhone 18 Pro Max using Vapor.
Specifically, the game averaged 66 frames per second during the city-driving segment. Other scenes recorded an average of around 80 frames per second.
The testing environment used 1080p resolution with DirectX 11. For the test, texture quality was set to High, and FXAA alongside 16x anisotropic filtering were enabled.
Furthermore, the settings included a population density of 75% and a distance scaling of 50%. The benchmark also enabled sharp shadows while turning off MSAA.
The iPhone 18 Pro Max incorporates Apple’s A20 Pro chip. Overall, the benchmark indicates that the PC version of GTA V can currently run above 60 frames per second on the iPhone 18 Pro Max at 1080p via Vapor.
