Well you can give it a try with the low-quality renderer.
The OpenGL 2.0 thing is really just an analogue for "not too old video card". Since that was written, I added in the low-quality renderer, so I should probably update it on the website!
Unfotunatly, I just checked the code, and the low-q renderer is still doing the opengl 2.0 check

otherwise that would work. But you never know, your card may be 2.0 or later anyway (even some integrated ones, like the one on my laptop are).
If you want to give it a shot, take a look at this doc for changing settings:
