Dear Ferdinand,

I just built and launched 5592/MinGW/QtCreator/compiled-as-downloaded on
Win7-64/i7/NVidia GTX580M (OpenGL4.2.0).

Performance here may be even slightly better than the pre-merge trunk
(running both in parallel, I have about 55fps vs. 51 fps for similar
settings, but both numbers are not stable, so I would say they perform
approximately equal).

But at least in perspective projection, with a "spherical" landscape, the
image corners in wide-angle mode are worse than before. See attached
screenshots. The triangles on the corners are extremely blurred. Is there
a bug in the texture mapping for clipped triangles?

Also, in stereographic mode, the tesselation appears to be much coarser,
so there are visible straight edges where there were none previously.
Compare screenshots:

The metal bars along the horizon are actually an artificial horizon, and
should follow the horizon markers. It's a square seen from the inside, so
there should be no edges at 90/180°. Here, also the illumination seems to
be too bright, the gray concrete is overexposed in the lower left.

So much for my first impressions. I will try to make a "release" build for
my netbook soon. Do I have to set this in CMakeLists.txt or is there a
setting in QtCreator for this? Also, where do I set a 64bit compile? (Is
this possible with MinGW?) I guess failing to load star catalog 8 is
caused by the 32bit addressing limit.

TNX, G.
