I have a brand new Alienware 17 laptop. It has an Nvidia 880M graphics card, 16GB of RAM, an intel Core i5 processor (@ 2.6GHz), but when I try to go into HMD Mode in the Second Life Project OculusRift viewer, I get the following error: "Cannot enter HMD mode because your graphics card does not support the minimum requirements. Vertext Shaders and Vertex Buffer Objects are required for proper rendering in HMD mode." I have added "NVIDIA GTX 980 .*NVIDIA .*GTX *98.* 3 1" to the end of my gpu_table.txt file (and even "NVIDIA GTX 880 .*NVIDIA .*GTX *98.* 3 1" to match the model number of my GPU), but I still get that message. Does anyone have any suggestions?
