Thank for the replay [:)]

I tried the jar executable version, i have the same performance.

And if i install previous java on my system the furniture icons using top view will start to appear wrong again.

So, i have no other choice.

I am going to use the last 6.6 edition.

Slow 2D view, slow visitor view, but fast 3D view.

I believe this is because i use the open source drivers of my nvidia graphic card. I don't want to install the proprietary drivers from nvidia.
