But those do absolutely nothing other than screw up your gameplay. I mean like reflecting water, clouds, swaying trees/grass, shadows, better rain, stuff like that.
Make sure you have a decent computer, I drop from 900 odd fps down to 120 with seus on. (w/ 128X TP though)
mc without mods, 30fps at spawn, mc with forge, liteloader, optifine and seus, 40 fps. The preview version of SEUS is improved in terms of lag.
You'll most likely be good. I get about that without mods, and with shaders I get about 40 fps outside of spawn, and about 15-20 at spawn. matthew_gruber http://www.minecraftforum.net/topic...rs-unbelievable-shaders-and-glsl-shaders-mod/
