Note:didn’t tested this myself i have no idea if it works and if it is worth it.
Dual GPU lossless scaling is a technique that utilizes two graphics cards in a single system to enhance frame generation and scaling without compromising image quality. This method allows a secondary GPU (or a APU, iGPU) to assist in rendering frames, improving performance in games and applications that support it.
Lossless Scaling, a tool available on Steam, enables this setup by leveraging a second GPU to generate additional frames, effectively increasing FPS while maintaining visual fidelity. Users have reported that this approach works best in modern titles, where the secondary GPU can handle frame generation without affecting the primary GPU’s rendering performance.
Setting up dual-GPU lossless scaling requires configuring your system to use a secondary GPU for frame generation while the primary GPU handles rendering. Here’s a general guide to get you started:
Steps to Set Up Dual-GPU Lossless Scaling (very simple basic explanation)
- Ensure Compatibility
- Check that your system supports multiple GPUs and that your secondary GPU is capable of assisting with frame generation.
- Lossless Scaling software (available on Steam) is commonly used for this setup.
- Install Lossless Scaling
- Purchase and install the Lossless Scaling tool from Steam.
- Open the application and configure it to recognize both GPUs.
- Configure Windows Graphics Settings
- Go to Windows Settings > System > Display > Graphics Settings.
- Select the game or application you want to optimize.
- Assign the primary GPU for rendering and the secondary GPU for frame generation.
- Adjust Lossless Scaling Settings
- Open Lossless Scaling and navigate to the Frame Generation section.
- Choose the secondary GPU as the preferred GPU for scaling.
- Enable LSFG (Lossless Scaling Frame Generation) mode.
- Test Performance
- Run a game or application and monitor FPS improvements.
- Adjust settings based on performance results.
