<pre>Hi,
I have compiled Cave effects demo of UE4 for Linux and as expected doesn't work
using Mesa open source drivers tested on both nouveau (GTX 470) and radeonsi
(HD 7970) drivers..
I uploaded the demo to Mediafire:
<a href="http://www.mediafire.com/download/0rav1j9033l784m/cave.rar">http://www.mediafire.com/download/0rav1j9033l784m/cave.rar</a>
Tried to run drivers using current drivers at
<a href="https://launchpad.net/~nzatkovich/+archive/bleediergraphics">https://launchpad.net/~nzatkovich/+archive/bleediergraphics</a> because they use
LLVM 3.5 daily so have support for GL 3.3 on radeonsi..
The demo runs by default using GL 3.2 profile and can be run in OGL 4.3 mode
via -opengl4 argument. This can be useful for testing Mesa against it when it
supports compute shaders, VAB and other features used by GL4 path..
Note demo runs on both Nvidia and AMD latest binary graphic drivers..
(See README inside file for more arguments and details on binary drivers used)</pre>
