CoCreate PE Tip: Fix for Intel X3100 Problems

I was having weird problems trying to run CoCreate PE on my Thinkpad: sometimes CoCreate would complain that the display resolution had changed, the model would disappear all the time (just from moving the mouse around), and such.

My Thinkpad has an Intel GMA X3100 integrated graphics chip (also known as the Mobile Intel 965 Express Chipset).  It’s not the greatest mobile chipset, but I was more interested in a small laptop with long battery life, and the laptops with mobile Quadros (e.g. Lenovo W700) are large, heavy, and have short (OK, normal) battery life.

Anyway, I found a tip via the CoCreate Users forum: turn off hardware graphics acceleration by setting the SDPIXELFORMAT environment variable to SOFTWARE; detailed instructions are here.  So far after making this change, CoCreate has been stable, and speed is still fine.
