Download the new 2.63a (http://www.blender.org/download/get-blender/). It fixes the rotation errors. If you are currently using that, then I don’t know why the mouse is going crazy.
I should mention known issues and bugs so far.
- OpenGL clipping not working or some GPUs (nvidia I guess), so it looks like in skycooler’s screenshot
- Moselook goes crazy on some Blender versions, but works fine in others. In latest svn version it works fine.
- some has reported that sun grabbing is not working, but it is a logic brick setup… so it is a Blender bug or something.
- and for some it does not open the file at all…
Confirmed that I do have an nVidia card.
Very cool. I was thinking about making some surf game. Could I use that for a start? Any licence restrictions? How could I make huge waves for surfing?
Thanks, seems I need to learn Blender game engine…altough I know Blender already.
wow you never cease to amaze awesome work martinsh, anyone else having trouble downloading from the dropbox links? 
Fantastic !
I can’t seem to get the “tweakables” to give big waves. Foam would be nice too !
Great work. I have the latest version 2.63a. Crashed on opening attempt. Started new project, imported your scene. Default camera comes out dark w just a few blue wave reflections visible. Switched to watercam, and i can see ground, sun, and underwater. Cant see thru water or get reflection/refraction.
That is some delicious water mate!
Really, with stuff like that and some performance- and usability improvements, BGE could be something big.
Btw. I got only black water. But when I dive into the ocean it works, just without the caustics.
Guess my Nvidia 9400m is simply too old for that fancy shader 
This is by far the coolest game graphics demo in blender ever.
I used the demo and it worked outstandingly fast for such a nice-looking shader. Blender game engine will now be one of the most awesome open source engines! (or the most awesome probably) Keep it up!
what causes that dark effect around the edges? all I know is it does it for anything submerged under the water.

I’m pretty sure I was using 2.63, but oh well. I did use it on another computer and it worked fine. Maybe it’s just my computer, or I need the new svn.
First of all, thank you Martinsh this is really outstanding and inspiring work! I would really like to use this in a VR demo I’ll be doing at the end of the month, but unfortunately I cannot get the last demo (ie. the one with submersion) to run. When blender opens all I see is a wireframe (even though the viewport is on textured mode) and nothing shows up when I run the game. I’ve attached a screenshot. Any ideas? Do I need a special build for this?
Thanks!
Resolved the issue by installing the latest build (2.64 from http://download.blender.org/release/) - was using the 2.63a (May 10th) release before.
Amazing work. I have a question about the underwater fog. Is it your own interpretation or is it based on any ‘empirical’ study?
Can the water effect be seen through a camera that I add to the demo. Dosen’t seem to work for me. If the effect only works through the watercam how would you change point of view to another player in a game?
I am rendered speechless.
Would using gl_ClipDistance help solving the clipping problem?
http://projects.blender.org/tracker/index.php?func=detail&aid=30262&group_id=9&atid=306
The clipping plane is not working on Nvidia, Blender 2.64.
Is this still about the bug in GLSL 1.20: http://projects.blender.org/tracker/index.php?func=detail&aid=30262&group_id=9&atid=306
Or has GLSL 1.30 been implemented in 2.64? In that case you would have to redo the clipping using gl_clipdistance, correct?
Moguri has committed the ClipPlane patch (NVIDIA) as r52523.
