15:13 < kagami_> TD-Linux: do you know how much tile-columns impacts on quality? I.e. is it worth it.
15:14 < TD-Linux> very rough estimate is 2% per tlie
15:14 < TD-Linux> of course can be tested on awcy

< BBB> wiak: tiles degrade quality/bitrate ratio by about 0.5-1% for 2 tile columns vs. 1 tile column, and 
       incrementally more as you increase the number of tile cols
