Hi everyone ,
My setup is PI5 8gb, Hifiberry digi2 pro, cooler, Waveshare 9.3HDMI, and Carplay CarlinKit CPC200-CCPA,
A problem is that ewerythin fly good (sound not tested yet)
But carplay is lagging and feels slowish I guess ,(HUDIY soft runs supper well no delay I'd say) is there any fix for it or it's as good as it can be TX

Hello, could you please send the output of the wlr-randr command? We’ll check the refresh rate, since it affects rendering.

Thanks for the output. Some displays report a refresh rate slightly lower than 60 Hz (by very small fractional values), but in practice they do support 60 Hz. In the new version, we’ve added some improvements to FPS negotiation with CarPlay/Android Auto based on the reported refresh rate. There will also be an option to manually set the FPS. This should make the projection smoother.
Currently, Hudiy is also running in the X11 compatibility layer. In the new version, it will be possible to run Hudiy fully on Wayland.
The new version will be released on September 15.
