# OptiScaler Client Linux

Be cautious with manager-style tools. Verify software sources carefully and do not assume a third-party manager or client is part of the core OptiScaler project.

Searches for OptiScaler Manager or OptiScaler Client often come from users who want easier installation and update management. The important point is to separate the core OptiScaler project from third-party helper tools that may use similar names.

## Understand the Translation Stack

A Windows game may use DirectX while Proton translates it to Vulkan. Some OptiScaler outputs can depend on newer Wine or Proton features, so an older compatibility layer can be the real limitation.

## Core Project vs Helper Tools

The core project can be installed manually: extract the ZIP next to the main game executable. A separate manager or client may be created by another developer, so its behavior, update source, privacy, and safety are separate questions.

## Is OptiScaler Manager Official?

Treat any manager or client as a separate product until its source is verified. The core install needs no helper at all, so there is no reason to assume a manager-style tool belongs to the OptiScaler project.

## Do Not Trust a Name Alone

A familiar product name in a page title does not prove affiliation. Verify the developer, package contents, update mechanism, and whether the tool changes extra system settings.

## Avoid Credential Requests

A graphics mod installer normally should not need gaming account passwords. Treat unexpected login, payment, or credential prompts as a warning sign.

## Practical Checklist

- Verify who publishes any manager or client before running it.
- Keep original files backed up before changing the game folder.
- Test one setting or backend at a time.
- Avoid anti-cheat protected online sessions.
- Document the working configuration before updating.
