Hi,
have the same problem right now.
Using Windows 10 on a Laptop with Intel HD Graphic 4000.

The 3D view is laging as hell and i installed Java 3D after this it seem to befixed for around 15 Minutes. The 3D View worked nice but than lags again.

If i load a saved project i can see that the models on the 2D view take much more time to load as before...

I dont know what to do now. Have tried Puybaret tip with the legacy igpu thing but without any effect.
