All hardware produced by NVidia from Geforce FX 5200 supports GLSL. That, of course, includes the series 6. Even if that, it's a whole different matter the performance you'll get. So, yes, your card is compatible. And I was busy, I can't be answering here all dayIS this playable on a geforce 6150le? 0_0 I googled it and got some weird statistics
EDIT: From what my eyes can gather from google. I'm guessing, no. XD ITsays it supportd shader model 3.0 but gah wheres Sash when you need him?
