Found hints to solve in https://bbs.archlinux.org/viewtopic.php?id=121001, glxinfo prints other lines with "rendering" for nvidia driver, and that confuses playonlinux check.

Another solution could be to check exactly for "direct rendering: Yes" with grep
by editing (as root) the file: /usr/share/playonlinux/lib/check_depend
and then inside macro "acceleration_check" (in line 60) change line

 if [ ! "$(glxinfo | grep rendering | tail -n 1)" = "direct rendering: Yes" ] && [ "$(which glxinfo)" ] 

by this:

 if [ ! $(glxinfo | grep -q 'direct rendering: Yes') ] && [ "$(which glxinfo)" ]
