Lossless Scaling is a game-changing tool that allows players to scale windowed games to full screen using sacling algorithms. This program keeps visual quality but also gives a huge boost to performance, making it particularly useful for modded Minecraft. Whether you’re running the game with or without shaders, Lossless Scaling can help you achieve smoother gameplay and higher frame rates without sacrificing graphics.
What is it?
At its core, Lossless Scaling is about boosting your FPS without sacrificing quality. This powerful program use scaling algorithms and machine learning-based techniques to improve performance. By allowing you to run games in windowed mode and then scaling them up.
Where to Get Lossless Scaling?
Unfortunately, this solution is not cheap it comes at the price of a whole 7$! (3.50 if you grab it at a sale :D). Probably now most of you have left but I just want to remind you it’s a one-time payment to use not only for Minecraft but for any game you want so it’s totally worth it in the long run.

Key Features of Lossless Scaling
Frame Generation:
The most important feature of Lossless Scaling is its ability to generate additional frames. This is particularly useful for games that don’t natively support frame generation, including normal or modded Minecraft versions.
Diverse Scaling Options
This program offers a wide array of scaling options to suit different needs such as LS1 (proprietary algorithm), AMD FidelityFX Super Resolution, and NVIDIA Image Scaling.
How to use Lossless Scaling with Minecraft
Now to the main topic how to use Lossless Scaling? It is quite simple actually, you download it open it then hit scale, and voila free fps! But let’s go into details for the sake of it:
1- After downloading the program through Steam you will find an executable on the desktop start it off:

2- You will be greeted by a window, a lot of options I know but we won’t need most of them
3- I recommend creating a new profile just for Minecraft since as I mentioned before you can use this program for other games. you can do that by clicking + Add.

4- Now to the important part: The Settings (I won’t go into details about what each option does, I will just show what is optimal for Minecraft):
-Scaling Mode: Set the scaling mode to Custom. The recommended value is 1.33, and it’s important to enable “Resize before scaling”. The scaling mode affects the balance between quality and FPS. A higher value results in lower quality but increased FPS. 1.33 offers an optimal balance between visual quality and performance.
-Scaling Type: After testing all options, I found that the game feels off with any scaling type enabled. However, if you need an additional FPS boost, try LS1 for the best results.
-Frame Generation: This is the most critical setting. Choose LSFG 2.2.1 (the latest version) and set the mode to x2 (x3 can be overkill).
-Performance Option: I personally don’t use this as it degrades graphics quality. However, you may want to experiment with it if you need more performance boost.
-Adjust Cursor Speed: Enable this if you notice a lack of synchronization between your cursor movements and on-screen actions. This becomes particularly noticeable when scaling is applied.
Fine-Tuning
Remember, these settings are general recommendations for Minecraft. The optimal configuration can vary based on personal preferences and your GPU capabilities. For maximum FPS boost, refer to the screenshot below:

here is a small video showcasing the Lossless Scaling effect, the fps counter is only showing 50 fps because I locked it at that value and OBS could not detect the fps counter provided by the program, but the actual fps is over 100 !! and trust me it does feel like it.
That’s all for this guide! I know it sounds too good to just download FPS but I can assure you it’s worth it and the cost is relatively cheap for what you are getting!
