In late 2021, Stardew Valley received the monumental 1.5.5 update. This patch migrated the PC version of the game from a 32-bit MonoGame framework to a 64-bit .NET 5 framework. SMAPI quickly followed suit, upgrading its core architecture to support the 64-bit version.
This 3 GB memory limit is the core of the entire discussion. For a heavily modded game, the combined memory footprint of the game itself, its assets, and dozens (or hundreds) of mods can easily exceed this limit. When that happens, your game will crash with an "".
Since the release of Stardew Valley 1.5.5, the game shifted its default framework from 32-bit XNA to 64-bit MonoGame. However, the developers maintain a for specific use cases:
This is the most reliable method if you are manually installing mods or using GOG Galaxy. smapi launcher 32 bit better
Using the 32-bit launcher prevents Stardew Valley from choking your system if you keep web browsers or music apps open in the background.
SMAPI is an indispensable tool that acts as a bridge between the game and its user-created modifications. It is required to run virtually any Stardew Valley mod, managing how mods load into the game and ensuring they work together. Without SMAPI, most of the thousands of available mods simply wouldn't function.

However, for anyone with a modern PC, the 64-bit launcher is objectively superior due to its ability to handle unlimited memory and its support for the latest modding features. Use the 32-bit version if you have to, but upgrade if you can. This 3 GB memory limit is the core of the entire discussion
If you only use a handful of lightweight mods (like basic UI tweaks), you might not need the extra "overhead" of a 64-bit environment. On very limited hardware, 32-bit code can sometimes be denser and more cache-friendly, leading to slightly faster performance in non-resource-intensive tasks.
Because memory is your tightest constraint, you must practice strict mod budgeting.

As of SMAPI version 3.18 and Stardew Valley 1.5.5, the game and modding platform transitioned to 64-bit .NET 5.0 (and later .NET 6.0). This change allowed the game to use more system RAM (crucial for heavy modpacks like Stardew Valley Expanded ) and improved stability on modern systems.
