Lagless Shaders Mod1.17/1.17.1 is the largest of Minecraft Shaders Mod because of its optimization. It’s perfect if you are tired of your computer stopping at each shaderpack you download and install! I recommend this Shaders Mod everyone who has an old or inexpensive computer.
The GPU recommended for Lagless Shaders Mod to have no lag are: *Minimum: Intel G41 Express Chipset Family and 2GB of RAM or higher *Maximum: Nvidia Geforce graphics card and 2GB of RAM or higher.
Thus your Minecraft should run this beautiful Shaders properly without a lot of work for your computer, if even with this mod you still can not have a good performance in minecraft, consider buying another computer focusing on the above requirements.
