Mesa 1.2 for AmigaOS 4 - Performance improvements and shader caching
According to benchmarks performed by the developer on an AmigaOne X1000 with a Radeon RX 570, the changes more than doubled performance in one of the Irrlicht Engine tests. Quake III performance increased from 160 to 190 FPS. The library also includes selected fixes backported from Mesa 26.1.6, 26.1.7 and 26.1.8.
