Feex says

If someone says turn on NIS, that is NVIDIA App. LosslessScaling.exe is the Steam overlay they paid for. I do not mix those names.

What is Lossless Scaling?

LosslessScaling.exe is a Steam overlay you arm, then it captures a game window. NVIDIA Image Scaling lives in NVIDIA App or the driver. Different product, different toggle.

If you have never used it

If you bought Lossless Scaling on Steam, this is a paid overlay that scales a window and can add frame generation. It is not NVIDIA Image Scaling, not DLSS, and not the NVIDIA App. Install it from your Steam library.

What is it used for?

Integer and other scalers on a window

You pick the game window. NVIDIA NIS is a driver setting, not this exe.

LS frame generation

The paid overlay path people mean by LSFG. DLSS Frame Generation is NVIDIA's in-game feature.

Steam-bought extra

It lives in your Steam library. There is no official "Lossless Scaling.exe" on a random host.

Who is it for?

People who bought the Steam app
Users who want FG on a game that has none
Anyone who confused this with NVIDIA Image Scaling

Current status

Lossless Scaling (2018) is a current paid scaler and frame-gen overlay from THS. The vendor still points Windows users at https://store.steampowered.com/app/993090/Lossless_Scaling/.

How old is it?

The Steam app dates to 2018 and grew frame-generation features later. NVIDIA Image Scaling and AMD RSR are driver-side scalers. Those are free vendor features, not this paid overlay.

Common problems

Enabled NIS and thought this app armed

NVIDIA Image Scaling is the driver. Launch Lossless Scaling from Steam for this product.

Overlay fights RTSS or NVIDIA overlay

One capture overlay at a time is the usual test. Afterburner is a different OSD.

Getting unstuck

Install from your Steam library (app 993090)

The Steam Community hub is support. Skip "Lossless Scaling free exe" sites.

Arm the overlay, then tab to the game as the app documents

It is not an NVIDIA App checkbox. It is not DLSS in the game menu.

Turn off other overlays when the image tears or the game refuses exclusive mode

RTSS, Discord, and NVIDIA overlay are the usual stack.

Alternatives

NVIDIA Image Scaling, DLSS, and AMD RSR/FSR are vendor or in-game paths. Magpie is another community scaler. This article is the paid Steam app.
