Shaders will work perfectly if your computer can handle them. The gates are not the issue. Mevans has no idea what the hell he is talking about with respect to this and my screenshot here will prove it (taken with beta 30 obviously since Dol Amroth towns cannot spawn in the jungle). It is the extended time in Middle Earth that interferes with shaders. Jump into the overworld first then return to Middle Earth and they will work until the time between Middle Earth and the overworld gets out of sync at which point you can either use game rules to disable the day/night cycle (/gamerule doDaylightCycle false) or use command blocks to alter the time. Or you could do like I did and hack the time in Middle Earth so that it is back to working the same as normal vanilla time - then all shaders work perfectly without going into the overworld first.
