Hi,
I'm making an interactive grided background:

it runs smoothly for about 10 seconds, then fps start to drop,

the debug overlay shows the draw event is taking quite long time,
in the draw event, draw_line() is called about 2100 times per frame, I wonder how can I increase the performance?
(I'm using YYC compiler)
Also, I curious why everytime I run it, the first 10~15 secs is always very smooth ,fps_real can upto 300~500, but then fps start to drop dramaticlly?

Looks to me like something that might be better performed using shaders?

I actually tried create a shader to make similar effect, but image 'wiggles' a lot, probably due to the supported texture's limited floating point percision.


Also, although I'm not tried yet, I've been told shaders don't work well on androids, is that true?
