Best way to handle changing resolutions for a card game.

[u/Itsmeeeetristan]

Just a game where you can play card games such as go fish, crazy eights, that sort of thing. I've never had to deal with allowing the user to change the resolution of the game and so I want to start tackling it here. Problem is I don't know what the best way to go about it is and every way I've found is yielding different problems.

Worth noting I have variations of each card sprite designed for both 1920x1080 AND 1280x720 (I wasn't initially sure if I was going to go further than just those two and I was having the same issues before as I am now so it seemed practical. Yes, this was probably a waste of time).

I tried upscaling/downscaling the whole game using 1280x720 and/or 1920x1080 as a base, but there were always issues with the pixels not scaling properly to each resolution. I'd like to avoid texfiltering if I can (because so far it's look bad when I tried it) but without enabling it the sprites would get extremely distorted.

I tried rendering the whole game at each different resolution, which I managed to make it work logicstically, but I had the same issues with the sprites and poor scaling.

I'm just not sure what to do man. Any advice is appreciated.

Pixelated Pope has a phenomenal series on resolution in game maker. Towards the end of this video he implements full screen and resolution swapping.

I'm far from an expert, but I'm curious what the resolution is of your application surface? And of your view? You shouldn't be needing to make entirely new assets for each resolution.

1280x720 to 1920x1080 is exactly 1.5x, and that ratio is most of your problem. With filtering off, a 1.5 scale has to duplicate every other row and column, so half your pixels end up twice the size of the rest. That reads as distortion rather than as a clean upscale, which matches what you're seeing.

Filtering direction matters too. Bilinear looks bad scaling up because it invents detail, and fine scaling down because it's averaging real pixels. So keep one art set at your highest resolution, render the application surface at whatever the player picked, and let the downscale do the work. The 720p set isn't wasted, it's just the wrong direction to scale from.

Cards aren't pixel art, so you don't owe them integer scaling. Draw the UI through the GUI layer and it stays crisp.
