So, I updated my GIT repository today from b22 to b27 after a couple months of being side-tracked with other tasks. I haven’t kept up with the goings-on here for several months so I’m hoping something very obvious has changed that I missed, but I’m experiencing a big performance hit using Primitives after upgrading to b27. To verify, I went out and tried the Sandcastle demos and I have the same problem with any demo that has Primitives. When those demos load, my entire desktop gets laggy, and the Cesium framerate drops from 60fps to ~10 fps with just one primitive in the scene. Performance picks up as I shrink the browser window.
Have the minimum hardware requirements changed? Have there been significant changes to primitives? I’m assuming this is a problem with my machine, but if I use my same application with the b22 build instead of b27, everything works smoothly, and I’m not sure why. I’ve looked through the last few months of discussions but nothing jumped out at me…
