What is Lossless Scaling: What It Is: A $7 Steam app that adds AI upscaling & frame generation (FG) to any game/GPU, bypassing hardware locks like DLSS/FSR. Perfect for older PCs, handhelds (ROG Ally/Legion Go), or games without native upscaling. Core Features Deep Dive 1. Frame Generation (LSFG) Purpose: Inserts AI frames to boost FPS (e.g., 30 FPS → 60 FPS). Key Settings: Type: LSFG 3.0 (lowest artifacts). Mode: Fixed: Strictly doubles FPS (40 → 80) – requires FPS cap at half refresh rate. Adaptive: Dynamically hits target FPS (no FPS cap needed). Target FPS: Match monitor refresh rate (60/120/144/165/240 Hz). Flow Scale: 1080p: 4–6 | 1440p: 6–8 | 4K: 8–10 (↑ = smoother motion, ↑ GPU load). Limitations: Input lag (avoid competitive games). Ghosting if native FPS < 30. 2. Upscaling Algorithms LS1/LS1+: Default for modern 3D games (best IQ/performance). FSR 1.0: AMD GPUs (RX 500+). NIS: NVIDIA GTX 10-series or older. Integer/xBR: Retro/pixel-art (sharp pixels). Anime4K: Anime/cartoons (reduces blur). Critical Setup & Settings 1. Capture API (WGC vs DXGI) DXGI (Windows 10): Default API. Dynamically adjusts output framerate for better frame pacing. Windows 11 Warning: May cause dark screens – switch to 8-bit color depth in NVIDIA Control Panel or use WGC. WGC (Windows 11 24H2+): Newly optimized for Win11. Lower latency than DXGI but requires stable FPS lock. Fixes cursor/overlay issues. Disables GPU scaling in drivers if black screens occur. GDI: Legacy option for ancient games. - if available. 2. Optimization Essentials In Fullscreen settings: Borderless Windowed ONLY (fullscreen unsupported). FPS Stability: Cap native FPS at half target using RivaTuner (e.g., 45 for 90 FPS). Exception: Adaptive mode works uncapped 7. VSync: Disable in-game -> Enable in Lossless Scaling’s Rendering tab. Max Frame Latency: 2–4 (+lag, -stutter) . Queue Target: 0 = High-end GPUs (smoothest) 1 = Balanced (most systems) 2 = Low-end GPUs (reduces stutter, if the GPU is overloaded). NVIDIA vs. AMD Optimization NVIDIA (GTX 10-series+): Default to dedicated GPU. Offload scaling to iGPU (e.g., Intel Iris Xe - integrated graphics) to -latency. Enable Bit-to-digest + S-Sign in Scaling tab. (in older version of Lossless Scaling) Driver Fix: Set Vulkan/OpenGL present method → Prefer layer on DXGI Swapchain. (in older version of Lossless Scaling) AMD (RX 500-series+): Same GPU rules as NVIDIA. Combine Max Frame Latency 3-4 + AMD Anti-Lag. Handheld Tip: Map F7 to a back button (ROG Ally/Legion Go) for instant FG toggle. Step-by-Step Setup Prep Game: Launch in Borderless Windowed. Lower resolution (e.g., 1600×900) if GPU-bound. Cap native FPS at half target (unless using Adaptive). Configure App: Select game process (Search). Capture API: Use WGC for Win11, DXGI for Win10. Scaling: Pick algorithm (e.g., LS1 for AAA games). Frame Gen: LSFG 3.0 + Fixed/Adaptive. Advanced: Set Queue Target (0/1/2) + Max Frame Latency (2–4). Activate: Click Scale or configure a shortcut → Alt+Tab back to game. Troubleshooting Black Screen? Win11: Switch to WGC or set color depth to 8-bit (NVIDIA). Disable Discord/GeForce Experience overlays. Input Lag: Use RTSS (NVIDIA) or AMD Anti-Lag + strict FPS cap. Set Queue Target=1 + Max Latency=2. Artifacts: Avoid 3× FG multiplier (use 2× max). Native FPS (lower settings/resolution). Missing Cursor: Enable Alpha Cursor Upload. Performance Drops: Disable second monitor and GPU overlays. Pro Wisdom "WGC + Queue Target 1 = Lowest latency on Win11 DXGI + Fixed Mode = Best frame pacing on Win10 iGPU Offload = Lifesaver for laptops" LSFG 3.0 cuts artifacts by 40% vs older versions. Critical: Native FPS must stay >30 for clean FG. Guide language lol: -stutter = minimal stutter or not at all. + lag = more lag. Informative app screenshot about the best settings for RX 7800 XT
