Best shader packs for older computers?

Hi there! I've been getting back into Minecraft lately and I really want to make it look a little easier on the eyes, but I don't have a very efficient computer. Does anyone have any favorite shaders that don't take up too much space or slow things down too much? Thanks in advance.

Depending on your computer specs (maybe you can share them with us so we know how to better help you), you might want to look into some of the most efficient shaders according to hp:
1.Sonic Ether's Unbelievable Shaders Mod
2.Sildur's Shaders Mod.
3.Lagless Shaders Mod
4.KUDA Shaders Mod
5.CrankerMan's TME Shaders Mod
