The mesh grass in my last post didn't really look very good IMO, so I tried
to make it denser and to add another light source, and I think it really
helped. However, it also increased the render time quite a bit, so that my
faked grass texture is faster now after all. I guess one can draw any
conclusions by now, but as many have said, each method will have its own
use.

Faked texture grass:
~~~~~~~~~~~~~~~~~~~~
Time for parse: 0 min.  0 sec.
Time for trace: 6 min.  3 sec.
Time total:     6 min.  3 sec.
Peak memory used:  0.36 MB


Real mesh grass:
~~~~~~~~~~~~~~~~
Time for parse:  0 min. 15 sec.
Time for trace: 14 min. 39 sec.
Time total:     14 min. 54 sec.
Peak memory used: 23.30 MB

Grass blades: 75^2*25^2 = 3515625


The grass texture looks a bit more boring with the second light source
added, because there's less contrast, but such things will always vary from
scene to scene.
