Graphics: Modern Power Meets N64 Nostalgia
v4.0.1 moves beyond basic upscaling and introduces features that blend modern PC performance with classic N64 visuals:
- MSAA Anti-Aliasing & Anisotropic Filtering: Smooths jagged edges and sharpens floor textures
- N64 Blur Toggle: Replicates the original hardware's dithered horizontal blur, preserving nostalgia for purists
- Direct3D 11/12 Removed, OpenGL Exclusive: The port now uses OpenGL, which ensures better stability and consistent rendering across platforms
- Fullscreen & Resolution Enhancements: Easy internal resolution multiplier with OpenGL upscaling

Gameplay Quality-of-Life Improvements
v4.0.1 also improves overall player experience:

- Casual Mode: Halves damage and removes drowning timers, ideal for younger players or relaxed playthroughs
Note: These QoL tweaks are inspired by community feedback and historic SM64 Plus features.
