After many many weeks of issues with star citizen, I finally tracked the problem down to a silly PCI-e riser cable that came with my thermaltake case. I am not suggesting for a moment that others will experience the same. I can only tell you that after extremely extensive testing, and CIG helping me along the way to eliminate the variables, I finally discovered my issue is a simple cable. I hope that this post might help someone in the future that is experiencing the same shader hang game crash issue I had. Thank you CIG for helping me and taking the time.
