We are developing a game for Android and iOS using SDL. Everything’s ready, but the iOS version is giving us some headaches due to image quality. We are currently having two problems: the background, which is a gradient, is shown using fewer colors, and the fonts are pixelated.
I think both issues are clearly visible in this screenshot from the simulator:
You can probably appreciate the font issue better if you open the image in a separate tab with right click on it.
The simulator is running an iPhone Xs with Graphics Quality Override set to High Quality.
I have disabled “Compressing PNG files”, but the result is the same. This issue is not always so visible, or, at least, not on all devices. I have tried the game on an iPhone 7 and I do not notice any image quality issues (backgrounds are smooth there).
Do you have any hints?
Thanks!
