Superluminal

⚡ Superluminal

Superluminal boosts your frame rate by rendering the game at a lower internal resolution and cleanly upscaling it back to your native display with adjustable sharpening. By reducing the GPU workload per frame, your system runs smoother and faster.

In addition to spatial upscaling, Superluminal includes a suite of GPU/RAM optimization tools, dynamic resolution scaling, and experimental frame generation, all accessible within a single unified settings screen.

ℹ️ Client-Side Only: Superluminal is strictly a client-side mod. It is not required (and does nothing) on dedicated servers.

✨ Key Features

📐 Spatial Upscaling

• Preset Profiles: Select from Ultra Quality (77%), Quality (67%), Balanced (59%), Performance (50%), or Ultra Performance (33%).

• Custom Scale: Set any custom render scale percentage to match your hardware preferences.

• Sharpening Filter: Fine-tune sharpening strength to maintain crisp textures and sharp edges after upscaling.

• Note: Uses bicubic spatial reconstruction with sharpening. (Not AMD FSR or NVIDIA DLSS).

🔄 Dynamic Resolution

• Automatically lowers internal resolution during high-load scenes (drops in FPS) and restores it when performance stabilizes, keeping your gameplay smooth near your target frame rate.

🎞️ Frame Generation (Experimental)

• Generates an extra frame between rendered frames using Interpolation or Re-render modes.

• Requires VSync enabled. Off by default, test it to see if it suits your setup!

⚙️ Performance & Memory Tools

• Culling & Limits: Built-in entity/block entity culling, particle limits, and adaptive render distance adjustment.

• Memory Management: Releases unused GPU memory when idle, includes optional heap sweeps, and provides smart RAM allocation advice.

• Profile Management: Instant preset application with a single-step Undo feature.

🛠️ Diagnostics & Usability

• Unified UI: Access settings via Options > Video Settings, the Mods screen, or a customizable keybind.

• Live Side Panel: Displays real-time metrics and explains the impact of currently active settings.

• One-Click Diagnostic Report: Copy system diagnostics directly to your clipboard for easy troubleshooting and bug reporting.

💡 Good to Know

• Graphics Settings: Upscaling automatically pauses when Fabulous graphics are enabled. Switch to Fancy to activate upscaling.

• Hardware Bottlenecks: Superluminal delivers maximum performance gains when your GPU is the primary bottleneck (e.g., high resolution, shaders, or high render distance). CPU-bound scenarios will see more modest gains.

• Troubleshooting: Enable Debug Bypass (under the Image tab) to view raw rendering output if visual anomalies occur.
