Forza Horizon 6 stutter, share your Apple Feedback numbers here

[gauthierpiarrette]

Forza Horizon 6's hitch about once a second comes from Rosetta. It handles the CPU exceptions the game's copy protection triggers about ten times slower than native code, and only Apple can change that. We filed FB25100017 with test programs and measurements, which are public here: https://github.com/gauthierpiarrette/highball/tree/main/spike/rosetta-trap-cost

If you see the hitch, send Apple a short report that names FB25100017. The guide has the steps and the text to paste, and it takes about five minutes.

Then post your FB number here with your Mac and macOS version. We add the numbers to FB25100017 as they come in, so the engineer who has our report sees every player behind it.

Questions about the guide are welcome here too.
