[Chimera-users] chimera 1.11.2rc crashes

Tue Oct 18 02:02:08 PDT 2016

Hi Elaine, Tom

I was going to order more RAM but after your email I am not. The good news
is that
chimera seems to be working now. As Tom suggested, I found an older driver
that doesn't hit any bugs.
The driver that worked for me is 368.22 with the *Stereo-Enable* option *On*
.

Many thanks for your time and helpful suggestions.
Yanni
