New Lossless Scaling update can reduce GPU load by 2x — Version 3.1 could be the most potent FSR/DLSS alternative yet
Dev also touts image quality improvements after ‘significant architectural improvements.’

Another killer update has been unleashed by the developer of the Lossless Scaling utility. For those on the lookout for an alternative game upscaling solution, the new LSFG 3.1 update comes with image quality and performance gains, potentially delivering “up to 2x GPU load reduction,” according to the developer.
The headlining 2x GPU load reduction comes courtesy of this tool’s new Performance Mode. According to the release notes, the new mode delivers this boost, depending on hardware config and settings, “with a slight reduction in image quality.” So, as is often the case with these kinds of tools, there can be a trade-off.
In some cases, it is noted that the new Performance Mode can, conversely, “improve image quality by allowing the game to achieve a higher base frame rate.” So, this is yet another graphical tweak that gamers will need to explore on a per-hardware-config, per-game, and per-preference basis.
Sticking to the topic of quality, the developer has announced that the following improvements have been introduced with the new LSFG 3.1 update:
- Enhanced overall image quality within a specific timestamp range, with the most noticeable impact in Adaptive Mode and high-multiplier Fixed Mode
- Improved quality at lower flow scales
- Reduced ghosting of moving objects
- Reduced object flickering
- Improved border handling
- Refined UI detection
Lossless Scaling utility refresher
Developed by a one-man band, the Lossless Scaling utility is a GPU-agnostic tool that provides an alternative graphics upscaling technology at the one-off bargain price of $6.99.
If your GPU doesn’t support technologies like DLSS, FSR, or XeSS, you may be attracted to Lossless Scaling to fill the gap with admirable performance and configurability. The tool has found a lot of fans within the PC gaming community, especially among those who sometimes find the best GPU they have at hand is an older discrete card or integrated graphics. But it has other use cases.
As well as offering up its own built-in upscaling options (like LS1, Nearest Neighbor, xBR, Bicubic CAS, and Anime 4K), Lossless Scaling can work its magic via AMD FidelityFX Super Resolution or Nvidia Image Scaling.

Like other upscalers, Lossless Scaling isn’t without its issues, particularly apparent when pixel peeping, or in games where frame gen latency is a no-no.
What’s next?
Though flagged as a “major update” and containing “significant architectural improvements” the Lossless Scaling tool version is only incremented by 0.1, to 3.1. Our inner marketeer would have perhaps suggested that LSFG move to version 4 to look more competitive against DLSS4 and FSR4. It already features machine learning enhanced upscaling. But for all we know, there may be even more significant updates and feature introductions in line to push the version up a whole number.

heffeque For those who have a dGPU paired to a half-decent iGPU, you can tell "Lossless Scaling" to use the iGPU for scaling+framegen, leaving the 3D part to the dGPU. Just set the "Preferred GPU" to your iGPU, and leave the "Display" as "Auto", and you're set!Reply
I have an Intel UHD 620 iGPU doing scaling, and an nVidia MX150 doing the 3D part. It's less than ideal because the Intel UHD 620 is cr*p, and the nVidia MX150 is also cr*p, but after some tweaking, it gets better frames than native without major visual difference.
In my case I can't enable framegen because my iGPU is not powerful enough to do scaling + framegen at the same time, but even an old Vega 8 iGPU can do a pretty decent job at scaling + framegen (when paired to a dGPU), so anyone that has an iGPU that's not terrible, do give it a try.
Personally I can't wait to receive my Framework Desktop to be able to retire this old laptop. Meanwhile... "Lossless Scaling" is helping me cope :sweatsmile:
