[Gear VR] GPU particles and horrible performance
I was learning / working with particles for my project and it turned out that GPU particles are horribly slow (and probably bugged/broken) in Gear VR. Here is the video with CPU particles (performa...
Exactly, I spent my last 3 weeks only doing trial and error, nothing i could find about limitations or bugs.

well, I got no time to revisit my posts into a single one. This issue should have never been an issue to begin with, or Oculus should have clearly outline what works and what doesn't in mobile VR.
If only UE4 was their #1 engine for mobile VR.. But, it's not..
HDR on with multiview--> one eye black
HDR off --> game crash
particle enable -- > game crash due material have either having "time, panner or MicroUV" which lead to crash probably not supported on GPU or a bug.
Distance node ---> game crash.
Pixel depth ---> game crash
And the list goes on etc... And every single crash I had to spend a few hours or even days to find out the reason behind it. I'm sure I'm not alone with this and all of us facing the same issue and you already beat us here and probably you spent more time than me since you were one of the first who faced these issues and I'm sure most of these issues are bugs and not limitation.
I spent more time fixing crashes and finding our limitation than the time I spent on my own game. I thought one of the good things about such Engine is you don't care about such thing and you invest your time on your game but I was wrong. the good thing is we can find each other's posts which confirm to us that it's not our project problem and its engine limitation/bugs. but the bad thing seems there aren't many devs using UE4 for GearVR as there are very few posts regarding GearVR and UE4.
