Current Features

Anti-Aliasing And Image Modes

• Added Off as a clean vanilla baseline mode.
• Added FXAA as a lightweight post-process anti-aliasing option.
• Added MSAA with 2x, 4x, 8x, and 16x sample options.
• Added SSAA with 125%, 150%, 175%, and 200% render-scale options.
• Added SMAA as a higher-quality spatial anti-aliasing option.
• Added TAA as a temporal anti-aliasing option with history-based smoothing.
• Added NIS Sharpen with adjustable sharpness strength.
• Added NIS Upscale with Quality, Balanced, Performance, and Ultra Performance presets.
• Added FSR1 Upscale with Quality, Balanced, Performance, and Ultra Performance presets.
• Added FSR1 + RCAS with the same preset options plus sharpening control.

Video Settings Integration

• Added an in-game anti-aliasing mode selector to the Video Settings screen.
• Added always-visible AA control bars that gray out when the selected mode does not use them.
• Added a Sharpness slider for sharpen-capable modes.
• Added an MSAA Samples slider for MSAA.
• Added an SSAA Scale slider for SSAA.
• Added an Upscale Quality slider for NIS and FSR1 upscale modes.
• Added live tooltips that explain what each option does and what each AA mode is best used for.
• Added automatic disabling of the AA selector while Improved Transparency is enabled.
• Updated the AA settings layout to fit the native two-column Video Settings style.

Rendering Rules And Compatibility

• Kept all AA, sharpening, supersampling, and upscaling effects limited to the 3D scene.
• Kept HUD, menus, and other UI elements out of the AA and upscale passes so they stay crisp.
• Added scene-only render-target control for post-process and internal-resolution paths.
• Added OpenGL-side handling for multisample resolve, supersample resolve, spatial upscale resolve, and temporal history flow.
• Added backend-neutral render structure so the mod is organized for a future Vulkan port later.

Debug Tools

• Added an edge-debug display that can be toggled with F3 + K.
• Added a black-and-white edge preview for checking edge detection coverage.
• Added on-screen edge-debug statistics for quick quality inspection.

Config And Persistence

• Added a JSON config file for the mod's settings.
• Added persistence for AA mode, sharpness, sample level, upscale quality, SSAA scale, and debug toggles.
• Added recordMetrics to the config, disabled by default.

Performance Metrics

• Added optional performance recording to JSON reports when recordMetrics is enabled.
• Added session-wide metrics such as average FPS, median FPS, 1% low FPS, 5% low FPS, frame-time stats, lag spikes, severe spikes, FPS drops, and low-FPS time.
• Added per-mode metrics so each AA mode records its own totals and per-minute rates.
• Added live metrics output to logs/salts_anti_aliasing_metrics_latest.json.
• Added archived per-session metrics files in the game logs folder on shutdown.

General Polish

• Added scroll-position preservation when changing AA modes in Video Settings.
• Added mode-aware settings behavior so controls update live without restarting the game.
• Added multiple rounds of visual and performance tuning for FXAA, TAA, MSAA, SSAA, NIS, and FSR1 paths.
