The most immediate benefit of switching to the decompilation is the noticeable boost in performance. The developers went beyond simply replicating the engine; they aggressively optimized it.
The official version of Sonic Mania runs on the Retro Engine (RSDKv5), which relies on specific platform wrappers to function on PC, consoles, and mobile devices. While it performs well on modern hardware, it carries background overhead, DRM constraints, and platform-specific bottlenecks.
The original PC release caps the frame rate at 60Hz. If you own a 144Hz, 240Hz, or OLED gaming monitor, the official game cannot take advantage of your hardware's smooth motion clarity. sonic mania plus decomp better
To understand the magnitude of this project, one must understand what a "decompilation" actually is. Unlike a typical mod, which alters content within the game, a decompilation takes the compiled machine code (the ones and zeros that the computer reads) and reverse-engineers it back into human-readable source code.
The decompiled community build comes with optional engine tweaks that feel like cheating (in the best way): The most immediate benefit of switching to the

The official version of Sonic Mania Plus relies on the original Retro Engine (RSDKv5) compiled for specific commercial platforms. While it runs well on modern consoles, the official PC version suffers from optimization quirks, heavy background overhead, and legacy DRM (Digital Rights Management) dependencies that can introduce micro-stuttering.
