If I understand correctly, Android devices have something called a "maximum heap size", the maximum amount of RAM available for an app. So for a 3GB Android tablet, the max heap size would be about 512MB, depending on what the manufactorer sets it at. If you wanted to target a lot of devices, you might set a 128MB or so heap size though.
My question is, will the Max Heap Size set by the device manufactorer affect the performance of Construct 3 or the Chrome web browser while using Construct 3 on the Android device? If you have the time, a sentence or two explanation might be good too, so I understand.
