Performance Questions? in Pixi.js Posted July 18, 2016 · Report reply Hi, sorry for the delay and not clarifying. We ended up figuring it out on our own! Essentially, we were trying to figure out what the FPS would be while rendering extremely large data sets. We wanted to compare Pixi to native WebGL to see what performance losses we would have while doing doing so. Note, this is using WebGL as a novice, ergo unoptimized and what basic tutorials can do (as we could expect an expert or advanced programmer or software engineer just learning WebGL to be capable of doing). Both are also only using 2D vertex sets. It may be interesting to you to know that we found that Pixi seems to be better optimized and corrected some intentional novice mistakes. Thus, we found that Pixi actually runs either very slightly slower (magnitude of .1 FPS) or actually a few FPS higher.
