[2019] Thanks for Metal support!

My experience of the stuttering improvement over time was that it was permanent, so please let us know your experience as you play games during the course of PTR and especially if it gets better or worse with the official 48 patch when compared to PTR. I’m keeping a close eye on it and what we really need right now is data.

That the performance got better over time, even after restarting the client, actually made finding the core issue much more difficult as it would seem to go away after a few debugging sessions. I was ultimately able to find the root cause by performing clean installs of macOS every couple days to allow me to capture the worst stalls again.

The best way you can help us right now is to play games on PTR! If you can get 4 or 5 games in, I think you will see a dramatic improvement, and the data will help us a lot.

Thanks!

Got it, thanks for the report. This is very helpful.

I would expect the stalls to return for a time after changing graphics quality settings, with the same effect of it getting better over time. Depending on how macOS is managing its Metal cache, the stalls may or may not return after switching back to previous settings.
