Demo updates

The water demo has been updated to use fixed point render targets instead. This means it runs quite a bit faster.
Thanks to Basic for spending the time to do fixed point versions of the shaders for me.

I also recompiled the earlier crop of demos based on the latest framework to these also include some new features in the framework, such as the console and ability to snap screenshot.

Works on Radeon 9600 Pro now...did you lose any precision when you decided to use fixed point instead of floating point?

Lose or win? Both!
The phyics filter is different, I think it's slightly better.

The normals are calculated in a different way, but it's mathematically equivalent.

Winning or loosing precision depends on the waves. For a "big" wave (as when you just made a splash), the integer version has 16 times higher precision than FP. This precision is maintained for smaller waves.
But FP precision increases as the waves gets smaller.

I got a little problem with that demo.
I got an ATI mobility radeon 9600.
So i can launch the demo and so i do

The demo starts and i can see the effect
but after few seconds it totaly freeze
my computer. I am up to date with graphics
drivers (note this is not the normal catalyst
driver) 7.91.4-030724a-010417C

So if some one got an idea.

My own opinion is that it is a dx9 prob as
dx9 freeze also with other application who
use it. And this was not happening with dx8.

Would love to see this one, however, gets as far as turning on AA, (still in Windows), beeps and gets no further. Hit escape, AA turns off.

I have GeForce FX5950 Ultra. Done all the registry stuff, all other demos fine, but not this one.
