Ashley Do you know if the settings in WebKit can affect our cordova ios applications?
There are some new experimental GPU settings in ios15 which many people claim to brake their HTML5 games. These are on by default in ios15, while they were off by default earlier.
Mainly GPU Process: Canvas Rendering and GPU Process: WebGL .
Also I've read that the new rendering better supports small textures than large ones, so setting small texture size might be better?
Since you are more technical mayve you have some insights, even though this of course is a Apple iOS issue and not C3. But still, I know you have some deep knowledge in the area
