14 High Fidelity Mobile Gaming requirements Sustained high-fidelity mobile gaming puts extreme requirements on GPU: High vertex counts High number of draw calls Complex vertex and fragment shaders Advanced graphics effects 14

15 Mali-G72 built for High Fidelity Mobile Gaming Digital Legends has a long history of designing visually stunning games on mobile Afterpulse is their latest first person shooter I had refused to believe a game like this could succeed on mobile, but Afterpulse has proved me wrong. Tom Christiansen, GameZebo Utilizing Mali optimization tools to reduce bandwidth and enhance gameplay Using advanced rendering techniques to maximize efficiency on mobile GPUs Digital Legends: Afterpulse 15

16 Afterpulse using efficient deferred shading on Mali A common rendering technique in High Fidelity games Decouples geometry from lighting Very bandwidth intensive Pixel Local Storage developed at ARM to enable deferred shading on mobile Allows efficient deferred shading by reusing tile buffers in GPU Minimizing bandwidth by reusing tile buffers data between several rendering passes G-Buffer Lighting Geometry Final 16

17 Afterpulse: GPU Write Bandwidth Mali-G72 built for High Fidelity Mobile Gaming Mobile gaming complexity is increasing Afterpulse is a High Fidelity Mobile Game by Digital Legends % saving 45% saving 68% Bandwidth saving Mali-G72 optimizations greatly reduce write bandwidth Mali-G71 Mali-G72 MRT G-Buffer PLS G-Buffer 17
