Polter was signed by QPR from Mainz in the summer transfer window, but he failed to make an immediate impact at Loftus Road.
The 24-year-old only played seven times for Chris Ramsey and Neil Warnock, during the two manager’s respective times in charge of the R’s.
Polter has, however, played a part in five of the six matches that Hasselbaink has taken charge of - and the target man says that things are getting better for him.
“It has been difficult for me, it’s a different league, a different country and I have to recognise everything for me; what is good; what is bad, and now with a new coach a new chance, and I have to get as many minutes as I can,” he said.
“I was not happy but now I have more minutes, so it’s better.”
Polter has scored in QPR’s last two fixtures, but his performances have not won over all the supporters of the London club just yet.
The German striker still has some work to do to convince R’s fans that he is ready for regular football in the Championship and he will be hoping to do just that in 2016.
With Charlie Austin currently out injured, Polter has big boots to fill in his first run of games in English football.
QPR are currently in 16th place in the Championship table, meaning they are under severe pressure to start collecting some victories.
