I have particles galore in my game. 16 emitters, 80 particles each, Physics rate of 60 FPS. It runs nicely at 45 FPS, constant.

Then the game ends. So I set the particle emissions to 0 on the emitters. This lets them fade out over the last few seconds. Then I freeze the emitters so there is no activity on them.
Now I'm back to the menu. No need to update Physics, so I don't. I start the second game of the session, unfreeze the emitters, set the rate back to 80 on each of them. In theory, I should be running at 45 FPS again. But I'm not, I'm now down to 23 FPS.

If I remove the emitters, I get a constant FPS every game, so it's definitely these that are the problem. I'm wondering if the Particle system is playing catch-up for the time it's being lying dormant.

I've used Set Physics Timer Bailout 1 to try and fix it, but it doesn't do anything. Anybosy have any ideas?

Are you talking about the "Cloth and Particles" expansion pack? If so, there are issues with it and we are to expect a new version coming out shortly (this week).

Yes, Cellbloc, that's the one. A bit sneaky, but I was helping Mike test some fixes, so I have the new version. Before you ask me to send it, the version I have is not compatible with U5.8 final.

I only got Cloth & Particles last Friday, so it's new to me. I wondered if I was using it incorrectly.

Since I posted, I implemented a new method, where I delete and recreate the emitters for every game. I get a slight improvement, i only drop about 8FPS now. So I obvioualy have some other "issues" to work out too.

Now that Enhancements is working, I get the FPS spoken to me using the voice commands - large!

Nah, I will wait for the "Final" version of the Packs. The last think I want to do is clutter my system with "beta/test" files.

Been playing again. I can now see that Particles are only a very small part of my issue. I have ramped the refresh rate up to 80 FPS. The second game drops to 38 FPS, whether I have particles active or not.

Can't find the damn cause though! I'm thinking it must be caused by the intermediate screens - hi-scores, Game Over screen, something!
