When you have frame rate problems, the first thing is to find out WHY you have those problems. Press F11 and check the render time display: that will tell you what the problem is.
After that the next step is making a plan how to fix that.
1000 particles are nothing for A7, they wont have noticeable impact on the frame rate. But 1000 physics entities are certainly a different matter.
There are only at max 20 physics entities! Not 1000!
It seems i cant get past 1000 (particles) without very significant slowdown though.
