Getting And A Mermaid Tale 2 Running on Modern Systems
I spent a week last month trying to get And A Mermaid Tale 2 to run properly on my machine. It's one of those mid-tier indie titles that doesn't age well out of the box, especially if you're on Windows 11 with a newer GPU. The issue isn't the game itself really, it's the engine it runs on and how it handles modern hardware. Here's what I learned the hard way.
Where to actually get And A Mermaid Tale 2
The official distribution goes through Steam or the developer's own storefront at mermaid-tale-dev.com/downloads. I'd avoid third-party reupload sites because the patched version they distribute tends to strip the anti-piracy stub which then breaks the config editor. Once installed, the default setup directory sits at Program Files/AndAMermaidTale2/. You're going to need access to that folder regardless of how you acquired the game.
The resolution bug nobody talks about
The game ships with hardcoded resolution options that cap out at 1920x1080 in the menu, even though the engine supports higher. If you're running a 1440p or 4K display you'll see stretched textures and UI elements that look like they were rendered at half scale. The workaround is simple but not obvious. Navigate to Documents/AndAMermaidTale2/Config/ and open display.cfg in Notepad. Change the line that reads ResolutionX = 1920 to your actual width, and ResolutionY = 1080 to your actual height. Save the file. Lock it with right-click properties if you want to prevent the game from overwriting it on launch. I learned this after spending three days thinking my GPU drivers were the problem. They weren't.

CPU stuttering on multiplayer sessions
And A Mermaid Tale 2 uses a single-threaded server loop for its co-op mode. If you're playing with someone over LAN or the built-in matchmaking and you have more than four background processes consuming CPU time, the game will drop frames in predictable bursts. It's not a graphics bottleneck, it's a threading issue baked into the netcode. The fix is closing everything except the game and running it in fullscreen exclusive mode. Borderless windowed makes it worse because Windows compositing adds overhead the game wasn't designed to handle. I cut my average frame time from about 45ms down to 18ms just by doing that and killing Discord's overlay.
Save file corruption edge case
There's a known issue where save files corrupt if the game crashes during the underwater checkpoint trigger. I hit this myself after a driver update caused my GPU to time out mid-session. The next time I launched And A Mermaid Tale 2, it loaded the save but the mermaid transformation ability was permanently disabled in that playthrough. The recovery process is:
- Navigate to Documents/AndAMermaidTale2/Saves/
- Find the most recent .sav file before the crash
- Copy it to a backup folder so you don't overwrite anything
- Delete the corrupted current save
- Launch the game and load the previous file
You'll lose any progress made during that session but the ability data is stored separately in a different file, so restoring from an earlier checkpoint usually brings the mermaid upgrade back. The modding scene for And A Mermaid Tale 2 is small but functional. The main repository is on NexusMods under the developer's verified account. The most useful mod I've found is the universal resolution patch which removes the hardcoded display cap entirely. Installation is just dropping the .dll into the root folder alongside the executable. Be careful with graphics mods. Because of how the engine handles texture streaming, throwing high-res assets at it can cause the same stuttering issues mentioned above. Stick to mods that target gameplay or UI unless you know your storage subsystem well enough to handle async loading bottlenecks.
System requirements reality check
The official minimum specs say you need a GTX 1060 or equivalent. In practice I've seen the game run acceptably on a GTX 1650 at 1080p low settings, but if you're on integrated graphics you're looking at unplayable frame rates regardless of what you turn down. The game's rendering pipeline has a base overhead that integrated GPUs can't absorb. Recommended is a RTX 2070 or Ryzen 7 3700X. Those are accurate. The game benefits from having at least 16GB of RAM because it streams texture data in chunks rather than loading everything upfront, and 8GB causes visible pop-in during fast movement sequences.
Anti-cheat considerations
If you're planning to play the multiplayer component and use any background monitoring tools like MSI Afterburner or RTSS, you may get flagged. The anti-cheat system in And A Mermaid Tale 2 treats hardware overlay APIs as suspicious hooks. I had to disable RTSS entirely and use the built-in framerate counter instead. It's annoying but it prevents false positives that get you kicked from lobbies. The developers are aware of this and have a ticket open but there's no ETA on a fix as of last month. If you're patient with the current state of things, the core experience holds up. If you need perfect background tool compatibility, you're probably going to be frustrated.
