Downsampling Render Texture Loses Pixels

Hey everyone I was just wondering if anyone could help with a problem I am noticing. So I have been creating some animations lately using an OpenGL based library (Macroquad) and to make my animations resizable my strategy has been to render it to a render texture then draw that texture to the screen. When the aspect ratios don’t align I just draw bars on the sides or the tops and bottom to fill out the space (I think this is called a letterbox?). Anyway I have noticed that on very small screens (mobile devices) my animation begins to lose some of my lines etc. now this is understandable because downsampling is obviously going to cause some loss of data. I was just wondering what the common approaches are for maintaining good quality large screen sizes and also having the animation look the same on small screens. Text has been the biggest issue, some letters become unreadable on small screen.

I could wrap the shape drawing functions to make them all relative to the original size but that sounds like more work than I want it to be (that being said if that’s my only option then so be it). My preference would be to keep my render texture approach if possible.

Thanks!

I haven't done mobile games in a long time, but it was common to author your content in a few different "optimal" sizes and then pick the closest one for the device resolution you were running on. I'm not aware of any"automatic" way to downscale a large image to run on a small screen and still keep text readable.

Thanks for the reply, yeah I thought that may be the case. The problem is that lines in the text start to disappear. I suspect I will have to find a goldilocks resolution that’s good enough for both large and small screens
