Resolution limitations? Can I use higher resolution?

[somnambulik]

Hi, sorry in advance if someone already posted that question, but i couldn't find any answer reffering to current AGS version. Are there any resolution limitations? I'm planning to make a game, already have some material, but I need to know if my sprites, backgrounds etc. won't be too big. We wanted to go for 2240x1440 with graphics rather complex than simple, but I found some old posts saying that higher resolutions can affect the engine's performance and generally create some issues. Is it still true or something changed? Or is there max resolution that we should stay with? Thanks.

My desktop runs at 1920x1080. Many people still use laptops that have an even lower resolution.
If I wanted to make a highres game with AGS I'd pick 1280x720 or maybe 1920x1080.

Regarding the performance: there have been lots of optimizations in recent years but one thing should still be the case: the higher the resolution, the more moving assets you have, the bigger they are, the slower the game gets. On an older machine, the FPS might therefore dip below 40 or whatever the game happens to use.

So the only way to find out whether performance is an issue is to actually build a test game and let people run it.

From my experience with many AGS games, any resolution proposed by AGS in the General Settings works great, whatever your screen resolution is.
You'll also notice that the options give a screen resolution ratio.
If you have a 1920*1080 screen (like most of people have), you'll want to go with anything that's 16:9, but if your game is, let's say, 640*480 (thus 4:3 ratio), it will still look great on 1920*1080, just with black boxing on left and right.
Even if you go for 320*180 (16:9), it will still look great on a 1920*1080 screen.

AGS does a really great job to have those low res games look perfect on a high res screen.

That's why the first part of my game was at 1920*1080, and the second part is 1280*720. Because it looks just as great for half the Mb pricel
Which also means you don't need to go 2k

Besides performance, you need to be aware that scaling 2D games down works quite badly, so anyone who cannot run in 2240x1440 will see a lossy, distorted image. It's much safer to do 720p or 1080p and then let engine scale it up to your bigger display, but then it will also run well for most people.

EDIT:
In theory it may be possible to readjust game camera based on display resolution, and have it display less portion of a scene at once. I've never tried, but I believe it may be done. Whether it will be convenient or not for the player, I cannot tell.
