Well said :-) The MSVM is utter crap.
But one thing that it outperforms the Sun JVM at is using old ImageProducer stuff for rendering (often used in 1.1 applets).

> sound JVM some time ago, dunno if things are still like that.

The IBM VM kicks ass. I don't know if they made an 1.4 JDK for windows in the meantime though (they do have one for linux), but in the 1.3 days it was well faster than Sun's VM in most cases. It is a more memory hungry though.

So much for nVidia's 'Unified Driver Architecture'... -sigh-
The quality of their drivers seem to be degrading over time anyway (for some games I have to install ancient drivers as well), so my next video board will probably be an ATI.

Ah, good. Well, good for me that is :-)

Well, I'm getting the scaling and filtering 'for free'. Other than that I suppose not.

I'm using the standard javax.sound (JavaSound) library, but I'm thinking about converting the code to openAL.

Thanks for your comments!
