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.

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).

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 (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.

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.

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.

"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.

-stutter = minimal stutter or not at all.
+ lag = more lag.

If you got this far, thank you for investing your time into reading my guide! :D
Hope I helped you fix your stutters and frustration, while using Lossless Scaling. I was in your shoes before.
Best YouTube video for explaining everything you need, honestly.
