Infinity Evolved crashes when using shaders.

[Sir Lags A Lot]

So I've been wanting to use shaders when playing. But everytime I try to use them on a multiplayer server, the official one btw, my game freezes, white screens me, then crashes. Although when I switch the chunk loading multi core, it's fine, but I get flashing chunks . When using Default or Smooth, i run into a crash. But using a render distance of 2 fixes it, but well 2 chunks is pretty unplayable. I play the modpack off of twitch. The shaders mod isnt being used as well.

This is the cut down error report.
