iOS 11 Simulator slow

Hello! I've been running my iOS 11 simulator on a fairly powerful machine. A 2010 Mac Pro with 64GB of RAM, GTX770 with 2GB of VRAM, and 2x2.66 6-core CPUs. No slouch. The iOS 11 simulator was noticably choppier than iOS 10's simulator. I tested on a lesser machine, a 2011 MacBook with 16GB of RAM, Radeon HD 6750M with 1GB of VRAM, and a 2.2GHz i7. Not a terrible machine, but a far cry from my mac pro. The simulator there works splendidly. The only thing I can think of is that the simulator is designed for AMD gpus, but that doesn't make much sense. The 6750M in the MBP cannot take advantage of Metal, but by GTX770 can. Not sure what to think of here

Really....nothing else comes to mind, like...it's a beta? What happens if you restart the MP and just run the Xcode 9 simulator?

Not sure your point - the simulator doesn't support metal, so...

Does that mean using Xcode 9 for both tests, or Xcode 9 (11) vs. Xcode 8 (10)?


Any change if you use the sim's Debug menu to deselect 'Optimize Rendering for Window Scale'?
