When Open Fancy Render with Carpenters Mod so... laggy and delay.

I use
Client #1
Carpenter Mod 1.9.3
MC 1.5.2
Forge 7.8.1.738
Options Render "Fancy"

and
Client #2
Carpenter Mod 1.9.3
Optifine 1.5.2 HD U D5 via Fancy Render
MC 1.5.2
Forge 7.8.1.738
Option Render "Fancy"

Laggy :v

But... Use Fast Render okay fine :)

I develop in MC 1.5.2 with Optifine and I haven't experienced the lag you speak of. Perhaps the Forge log is showing a stream of errors?

I'm going to assume this has been resolved.
