Please ¡¡PLEASE!! make Lossless Scaling compatible for Linux, Steam Deck need a program like THIS, i'm begging you.
I don't care if you release another program for scratch that cost the double, i'll buy it twice.

This tool brought us frame gen x4 back in 2024, when Nvidia kept DLSS4 still a secret. Then they said that the 5070 is better than a 4090, thaks to frame generation of course, not actual render performance. Well this tool right here, balances the playfield just do 4x frame gen to stand there and be proud that now you can say "No, the 4090 is actually better than the 5070, I used frame gen x4 to show you the pErFoRmanCe comparison of both cards running 1080p with an upscaler and 4x frame generation, because benchmarking 1080p would have shown you the same"

This is hands down the most valuable app I currently have. It’s the main reason I still run Windows on some of my PCs. The team behind this app is both exceptional and approachable.

The app delivers on two major features, and you can activate either one or both at the same time.

1. Double or Triple Your Frame Rates.

Ideal for users who struggle to hit their target frame rates.

Also, great for those who want more efficiency — reducing noise, heat, and power consumption.

I personally use it to cap my frames at 70 FPS and then double them to 140 FPS. On my older PC, which I stream to my Steam Deck, I cap at 45 FPS and double it to 90 FPS.

2. Upscale Your Graphics for Better Performance.

When compared to DLSS, FSR, and XESS, the LS1 upscaler used by this app stands out as the best to save you time. If you don't want to waste time testing each upscaler, just use LS1.

On my 1440p monitor: I run it natively without any upscaling. I just use Frame Gen to double my FPS from 70 to 140. Not 144 to factor in GSync/FreeSync.

For my Steam Deck, using Moonlight, I upscale from 1080p to 1200p. Since 1080p is already an upgrade over the Deck's native 800p, this provides a noticeable improvement.

On my 3k and 5k screens, I upscale from 1080p and 1440p. After pixel-peeping across various resolutions (1080p, 1440p, 1600p, etc.), I can confidently say that it’s difficult to spot a difference. So, starting with 1080p or 1440p works perfectly fine. Note it depends on your screen size because that affects pixels-per-inch.

Edit: I removed the suggestion to turn on performance mode. As of LSFG 3.0, there isn't a need for performance mode as they've improve efficiency by as much as 50%! Turn on only if you need it, and/or set resolution scale to 90.
