And then get a few of us to run that updated program and > post results. I've added sphere with 10, 64 (default) and 200 divisions. Note that this number is approximate because the sphere mesh corrects the division number with `newDivisions = ((oldDivisions + 3) / 4) * 4`. [attenTest.zip](https://github.com/openjdk/jfx/files/4855989/attenTest.zip) Using AMD RX 470 4GB on Win 10, all 3 spheres averaged 120 fps both before and after the patch. (It takes a couple of measurements to hit the consistent fps, so I discarded them.) ------------- PR: https://git.openjdk.java.net/jfx/pull/43
