I noticed that when I am in fullscreen mode and have VSync enabled I got very low fps. In window mode with VSync there is no problem. If I disable VSync for both (fullscreen and window mode) it runs normal too. It is just the combination of fullscreen and vsync causing a huge fps drop down to ~20 FPS or fewer.
I am not sure if this is hardware related or has anything to do with JME ?! I use 3.1 xbuf snapshot.
Maybe someone can comment on that.
My hardware is:
AMD Phenom II 840 3.2 GHZ quad core
NVIDIA Geforce GTX 760
8 GB RAM
No, not really, I tried to set the frame rate to value of 1000, just to see if it has an impact, but no it hasn’t.
EDIT:
I restarded my computer, ran the application again and now it is fine again. I have no idea but maybe there was something interfering with something (if you can say so). When I know where exactly that problem came from, I will tell you.
