yeah urt has now 27's new bumpy.exe included.
that bump effects u can turn on, u can turn on the special water like u might have seen in that video of Ramelle. but 4.2 will run on any machines where 4.0 ran onto (my pc supports 4.2! yeeha!)
but as u know for good results like fps (on slower pc's) u have to turn off that bumpmapping effects and teh new water. lowest settings will run teh game perfectly @ fps.
i hope i get a better pc before 4.2 comes out....
