  • Problem Description

    Frame rate drops when playing the game with node webkit. It will drop to around 30-40 FPS then go back up to 60.

    It only happens in node webkit. I have tried disabling the code and enabling to find the problem to see if it was the code's problem but

    the game runs in chrome fine and ran fine before the new node webkit v0.13.0 beta 4 (Chromium 48).

    A link to more people having the same problem.

    Attach a Capx

    My capx is large and almost done and I am having problems recreating the problem with a smaller capx.

    I have been trying to replicate the problem with no results. I did try using the other NWJS versions and by using v0.13.0 beta 2 (Chromium 47) the game will have 1 lag spike or none most of the time.

    Is there anything that effects running NWJS the most? I am happy that older one runs the game good but I want to be sure that I could update NWJS eventually and have no problems if I'm the only one with the problem and it doesn't get fixed.

  • NW.js is based on the same browser engine as Chrome, so I find it difficult to explain why there would ever be a performance difference between the two.
