Font Loading - memory difference between SDK 3 and 4

Did anything change between SDK 3.2 and 4.0?

E.g. I tried to load approx. 20 fonts in my watchface on the Fenix 7X simulator and the watchface shows 81kB but when I switch to the Fenix 6X it crashes with a OOM exception when approx. 10 fonts are loaded.

Is this a sim bug? I wonder how the Fenix 7X simulator can load so many fonts and if this will be the same on a real device?

No, it's a difference between CIQ 3 and CIQ 4 devices. With devices like the fenix 7, there is a graphics pool, where things like custom fonts are loaded there and not in the app's memory. See

Using the original Venu and the Venu2, the Venu allows 500k for a watch face, while the Venu2. 124k. The reason being the graphics pool on the Venu2.

Thanks for those details. This means I can rely on that I can cache my loaded fonts on devices with CIQ 4 if the sim shows that their memory impact is accectable?

You can trust the sim with this.
