Hi there,
Since updating to 4.1 I’m getting really awful spikes when testing the game on my Galaxy S4. Each time a spell is fired (projectile/particles/sound/animation). There are really huge spikes. Prior to 4.1 there were none at all (at least nowhere near this level).
I tried to revert back to 4.0.2 but too many assets had been changed and would no longer open. I got the project to build by changing a few things but my map and general assets were not able to open anymore.
I know people have had FPS issues in the editor. Which I don’t seem to have. I did try the fix for the sake of it but it didn’t make a difference.
Really troubled now as my game is unplayable 
As always, any and all help is very much appreciated.
Thanks
Edit: Should also add. From my experience (and perhaps I’m doing it wrong!) but there’s sometimes a small spike when things are instantiated for the first time. Then (I assume) their cached/pooled so subsequent requests are faster. And so with that in mind, could it be something to do with the cache/pool?
Actually, how does object pooling work in UE4? I had to write my own in Unity.
