Do not bind same texture again, it will drastically change render performance
F.e. on an average Map (Cube 256x256) when full map is shown in viewport
there are only ~1250 new texture binds, when all other ~64k binds can be skipped.
Measured performance on my PC:
for ~40k tiles DoTiles was executed in ~41ms.
After optimisation - downto ~11ms.
from 12fps upto 20fps
for ~65k tiles in viewport
from 69ms downto 22ms
from ~7.5fps upto 12
