Warren has finished on the losing side twice so far, his sole taste of victory coming against Zebre last month.
But the Wales centre is sure as the season goes on his decision to move will become justified.
"I am enjoying playing so much and when the results and performances turn I will enjoy it even more," Warren told the South Wales Argus.
"I am trying to create a good impression at the Dragons and sometimes when results aren't going your way you can feel that you aren't doing enough.
"But my aim was to move to a new environment and to push for a starting place, which I've done. I feel I am improving here and want to try and put as much input into the team as I can.
"Things will turn for us soon and then I can start putting myself into the game plan even more."
