Low FPS

Recommended Posts

@PhilT welcome to the forum from me. The Gamelets are starting points for ideas using Babylon.js and as such were written as explorations and are about potential rather than efficiency and effectiveness. As Jerome said the PG is CPU intensive and time is of the order(N*N) where N is the number of balls, so for time of order 4 000 000 perhaps 10fps is not too bad for a start.

In my old Athlon x2 with the GTX 650, it runs at 4fps (with 2000 particles, which are a lot :)). With less than 200 particles I can get 60fps, and with 400, 30fps.

 

But as you have already been told, the trigonometric calculations of the intersections consume a lot of CPU time. It seems totally normal to me.

Thanks for the welcome, John :)

And thanks very much for the responses. Yeah, those are some big numbers! Good to know others are seeing similar performance. I'm still experimenting with BJS and trying to get a sense of what could be achieved and what the limits are.
