The NVIDIA Control Panel allowed me to disable SLI completely and I even rebooted. I also upgraded to Java 8u72.
Sadly JavaFX still performs like a one-legged dog dragging a cannon ball on a chain. All other 3D apps, games etc. perform blindingly fast as I would expect. So, if it's not an SLI or driver problem, what is going on here (or not going on)? Felix > On 30 Oct 2015, at 19:47, Felix Bembrick <felix.bembr...@gmail.com> wrote: > > That's curious.
