Curious.. any ideas on the little green box in the top right? It's static and unchanging. 

Damnit, just realised that. :)

ReDiLab works fine on the iPad Air - what's the fundamental difference between the two codebases? Just the shared memory technique?

I've made some progress. It seems to be related to number of thread groups you're dispatching: Relevant code: ``` let threadExecutionWidth = pipelineState.threadExecutionWidth let threadExecutionMax = pipelineState.maxTotalThreadsPerThreadgroup particle_threadGroups = MTLSize(width:(particleCount...

Reading the [Apple Metal Programming Guide](https://developer.apple.com/library/ios/documentation/Miscellaneous/Conceptual/MetalProgrammingGuide/Compute-Ctx/Compute-Ctx.html#//apple_ref/doc/uid/TP40014221-CH6-SW1) > Executing a Compute Command, it seems to me that the second param to dispatchThreadgroups should be a multiple of the threadExecutionWidth, up to...

Intuitively, I feel like the A7 and A8 are acting very differently with respect to the dispatchThreadgroups call (based on our having to dial it down so much to even...

To save whoever picks this up some time, I tracked down the ioq3 Vita (aka psp2) touch screen code in this commit: [https://github.com/Rinnegatamante/vitaQuakeIII/commit/4f978095105895a42127d0173f01a740b2ed66df](url) Looks simple enough!
