[Second life project oculus rift cant connect]

ive gotten my graphics card to work well now, but now that that's over, the viewer cant find my oculus rift. it says the hdm is not detected

[whenever I try to enter the HMD mode, It says my graphics card doesn't have the minimum requirements]

so the notice say i can use HMD because i dont have the minimum graphics card requirements. it says "vertext shaders and vertex  buffer objects are required for proper rendering in HMD mode.

ive never had issues with oculus or second life before on graphics, so i dont understand the issue
