Hi,

I'm compiling a natural landscape scene (mountainious region) and I tried
the following set-ups:

1. 720x576 and antialiasing switched on (Sampling_Method=2)
   rendering time: 5:15

2. 2160x1728 and antialiasing switched off
   rendering time: 2:57
   2.a downscaling to 720x576 with external software (irfanview)

The results look in my eys quite compareable but are are there some general
reccomendations what is the better way to render the images? Especially
when rendering animations the advantage in speed is appreciated.

Thanks for suggestions
Wolfgang

The results are likely to be very similar between your two approaches,
except in some rare situations (for instance, very thin objects might not
anti-alias well even though they would appear in the second method.)

In almost all situations, I'd recommend you use the first method, since it
basically does the same thing as the second method except that it avoids
doing extra work in areas that don't need anti-aliasing (it's faster).
