Exciting news for PC gamers! AMD’s FidelityFX Super Resolution 4 (FSR 4) can now be used in nearly any game that runs on DirectX 11 or 12. This breakthrough comes courtesy of an update to OptiScaler, allowing users with Radeon RX 9000 series GPUs to unlock this advanced upscaling technology.
OptiScaler is an open-source tool designed for gamers who want to enhance their gaming experience. It enables you to replace an existing upscaling method, like FSR 2, with the latest FSR 4. This means that even if a game hasn’t officially supported FSR 4, you can still take advantage of its superior capabilities.
Essentially, you can enable FSR 4 in games that typically feature older technologies like FSR 2 or DLSS 2 without needing input from game developers.
Even though OptiScaler isn’t officially backed by AMD, it only tweaks local files. Following this method is low-risk if you ensure to back up your game files, especially for single-player titles.
Requirements and Limitations
Before diving into how to enable FSR 4 with OptiScaler, let’s discuss what you need to make this happen:
- GPU Compatibility: Make sure you have an AMD Radeon RX 9000 series GPU. FSR 4 is designed for these cards, which are equipped with the necessary AI hardware.
- Game Engine Support: The game must be running on DirectX 11 or 12. Currently, OptiScaler lacks support for Vulkan or other graphics APIs.
- Game Type: Avoid using OptiScaler with multiplayer games that include stringent anti-cheat systems like Easy Anti-Cheat or BattlEye to prevent any account suspensions.
- Per-Game Setup: You’ll need to configure OptiScaler individually for each game, as it doesn’t have a universal toggle.
How to Enable FSR 4 in Your Games
Getting FSR 4 up and running with OptiScaler involves some simple manual steps. Here’s how you do it:
- Download the latest version of OptiScaler from its official GitHub page. No installation is necessary; just extract it into a folder.
- Ensure that your AMD Radeon drivers are current. Go to your game’s main install directory and find the folder containing the game’s executable. Copy all extracted OptiScaler files here, replacing any existing files if prompted.
- Open the file named OptiScaler Setup or Windows Setup. If a security prompt appears, click Run Anyway.
- A setup window will open where you need to choose a filename for the new OptiScaler DLL and select your GPU type, as it supports Nvidia, AMD, and Intel.
- You can choose DLSS-based inputs as needed, although this isn’t essential if your game already supports FSR 3 or higher.
- Start your game, and open the OptiScaler in-game overlay by pressing the Insert key. Select FSR 3x from the dropdown menu and click Change Upscaler to enable FSR 4.
- Finally, you will have FSR 4 enabled within the tool, but remember, each game requires its own setup.
- If you encounter issues getting FSR 4 to work, more information can be found on the OptiScaler GitHub Wiki page.
Upon completing these steps and replacing the necessary files, your game should start rendering with FSR 4, offering enhanced image quality and improved frame rates compared to older versions. Despite this, be aware that it may not match NVIDIA’s DLSS in terms of visual fidelity or performance.
By using OptiScaler, you’re effectively unlocking FSR 4 for a vast array of DirectX 11 and 12 games, expanding its reach beyond the limited officially supported titles.
Bear in mind that your experience with performance and visual upgrades may vary based on compatibility and the quality of the original game assets.
