First of all thanks for the support and sorry for my bad english.
I'm porting the WP game Cosmorphosis to Android using Monogame and Farseer Physics and everything was fine until I test the game on the telephone
In this phone the game is running with lags from 10 to 30 FPS, so... you can't play on it.
Searching for a solution I found the application
Farseer Physics Android
I downloaded it and I realized that "Texture to vertices" for example is running at 5 FPS if I move the texture.
So, maybe this phone does not supports Farseer Physics for Monogame. My question is, what would be the minimun requeriments to have at least 30 FPS with monogame and Farseer?
Thanks and regards.
