Don't have any problems with it.

What IS recource hungry? Would you please specify that?
What is more recource hungry than image processing and rendering large scenes?

Got it.

That's image processing again.

Well, for me, not. Win95 uses much ram and drive space and even cannot force 
the 16bit apps to multitask smoothly.

Just your opinion.
