Hmmm, interesting move!

But, just for the record, didn't you guys also crammed a d3d9 render path to the rendering interface?

Windows 7 64 bit FTW.

Though i would rather get the ps3 varsion.

That looks a lot like the code OpenCL generates for my kernels... :-P

I like this water demo a lot, its very smooth and realistic.

Could you please make it into a .scr or some sort of screensaver?

Hi,
will the new framework4 abstract OpenGL 3.x(2) and D3D11? If so, i would really like a look at your abstraction, because i am working on a similar project right now and i always get the "if i want to have this (very rare) feature, how can i abstract it for both" illness .

keep up the excellent work!

FMoreira: Yes, that's a Release build. Debug builds generate function calls building the StringHash class and everything. That 64bit is faster could very well be due to double the amount of registers available, so far fewer reads/writes to the stack. I did some SIMD optimizations at work which dramatically improved our performance, which mostly was about keeping things in registers and avoid the stack.

Arseny Kapoulkine: Yes, that's true. Although I would have expected that the compiler would do a final pass over the generated code and eliminate sequential writes to the same address.
Using a single local variable worked too, so I'll use that instead since it looks better (and is less prone to copy-paste errors).

Martin Vilcans: Yeah. It was just a coincidence that I noticed this, because the code was working. I was looking at other stuff when I suddenly saw that chunk of code above the code I was really looking at.

At least it doesn't generate invalid code, which has happened to me at least once in Visual C++ 2.0. (Way back.)
