Cap your in-game frame rate to 30 FPS or 45 FPS using an external limiter (like Rivatuner). Use LSFG to boost the output to a smooth 60 FPS or 90 FPS while saving battery power.

Lossless Scaling v3001 Portable is a lightweight, portable build of the Lossless Scaling application, which upscales game and video output in real time using GPU-accelerated image scaling and sharpening techniques. The portable variant requires no installation and is intended for users who want a quick, non-invasive way to enable upscaling on Windows systems.
While the portable version is fantastic, it has two minor limitations compared to the installed version:
Negative or cautionary feedback includes: While there is no native "portable executable" (it
The primary benefit is the elimination of a formal setup process. Users can simply download the archive, extract its contents, and run the executable. This is especially useful for those who want to test the software before committing to the purchase on Steam or for users who frequently reinstall their operating system.
Even on powerful systems, Lossless Scaling offers value. It can push frame rates beyond what the hardware would normally deliver, smoothing out demanding titles and improving experiences on high-refresh-rate monitors (e.g., turning 120 FPS into 240 FPS on a 240 Hz display). Some publications have framed Lossless Scaling as a serious competitor to DLSS 4, particularly praising the LSFG 3.0 update for bringing multi-frame generation to all GPUs, not just NVIDIA’s latest RTX 50-series.

LS1 is the proprietary spatial upscaling algorithm developed specifically for this tool. It offers sharp edge detection and minimizes the "shimmering" effect common in traditional upscalers. It is ideal for 3D AAA titles. 2. AMD FSR (FidelityFX Super Resolution)
