A case study from Intel shows the power behind their Graphics Performance Analyzer (GPA) as used in optimizing the Neoqb game “Rise of Flight”. The study has several interesting examples of how they used GPA to locate bottlenecks and reorganize code for some fairly impressive performance improvements.
Two scenes were the target for my optimization efforts. After analyzing a frame from the first scene with Intel® GPA, performance was increased nearly 70% for that frame, from 41 frames per second (fps) to 69fps. Similarly, the second scene improved 55%, from 40fps to 62fps. After completion of Neoqb’s game optimization using Intel® GPA, Rise of Flight now runs about 15% faster across the board, with some components running nearly 50% faster.
