32-bit systems are limited to roughly 4GB of RAM. Large mods like Stardew Valley Expanded often exceed this, leading to "Out of Memory" errors. 64-bit systems can handle much larger mod lists and high-resolution assets. smapi launcher 32 bit better
Stardew Valley was originally built as a 32-bit application. While ConcernedApe and later Eric Barone updated the game to support 64-bit executables, many of the underlying assets, shaders, and legacy framework mods were coded with 32-bit pointers in mind. When you force a 64-bit environment on a mod that expects 32-bit precision, you introduce and stack overflow risks . (the Stardew Valley Modding API) primarily support 64-bit

The launcher matches the bitness of the game’s underlying native libraries, allowing those unmanaged DLLs to link without friction.
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:
On very old machines, 64-bit architecture does not always guarantee better performance for lightweight applications. If a user is playing vanilla or with very few mods on a legacy laptop, the 32-bit version may actually run slightly smoother. It often has a smaller memory footprint for the game logic itself, provided the game does not exceed the 2GB to 4GB RAM limit of 32-bit applications.
