I am beginning game development and using texture atlases. I've created textures based on the resolution 1920x1080, so I created a 1024x1024 size Texture Atlas for storing multiple graphics.
If the game is played on a 800x480 size device, the atlas will be very big to load in memory. An atlas of 512x512 would be enough and on devices with 480x320 resolution the game might not even work due to the different texture size.
How can I resize the atlas to save memory? Can I use different texture atlases for different screen sizes?
I just want to know how other game devs do it?
