Crash, crash and more crash

[C.A.D]

My pc is bad as it is, playing in Ra was no longer an option for me. However since CoR was officially launched, in the settings area there is no longer an option for OpenGL. Playing on D3D looks nice etc however I can no longer fort war. If I run into a group of more than 15 people (Ally, Enemy or both) I instantly crash. At Imperia the other day I crashed 7x in a row, eventually I rage quit.

Note: I plan on getting a better pc soon, but for now any solutions on what I can do? =/
