So I realize this is a problem for anyone developing a windows 8 app and expecting it to work on the RT line. The performance is terrible. I get about 65 FPS when I test a native app on my win 8 computer and about 55 on android devices with crosswalk. On my surface rt it runs around 25fps and drops to a craw around 15 sometimes. Anyone have any ideas on how to improve Performance on the Surface line?

My app uses Physics and Text objects and Ill probably switch to using sprite font but I want to keep using the physics engine.

Thanks

I get a similar error now. It says Assertion Failure: Physics polygon separation resulted in no polys. I have no idea what it is. I have narrowed it down to one object on the screen that does this.

It seems the file is too large to upload over 2mb. I think the version I worked on it was 163. The 2 files of the game that feature and ajax request to a php file are the only ones that give me the error. They were fine not that long ago when I was working on them.

I'm using windows 8 have been for all my development.

Edit: I got one of the capx files to work by loading up the backup of that file. Its not the newest one but it does have a lot of the latest changes to my game. Im still confused about what would cause this problem.

I should add that all my files are kept on skydrive(onedrive).

It is my file. I moved it to a new computer.

I keep getting "encountered an improper argument" when trying to open a capx file. Any help?
