Comparison between GPU and CPU particle systems.Computer games have used particle systems for visualeffects such as weather, smoke, fog, etc and it’s relatively low costto implement. There are a mixture of different techniques usedto render particle systems, usually CPU heavy implementationsor a GPU based one.In this study we developed two rendering techniques for aparticle system, instancing and stream-out, and compare theirperformance. As almost as expected we saw that the stream-outtechnique that is GPU based outperformed instancing when wetested using none intractable particle systems. We have furthereddiscussed both advantages and disadvantages in other scenarios.
