I work for an AEC firm and am using my HMD for presentations and project coordination. In preparation for an upcoming presentation, I revisited a 3D model I created with various Autodesk products. Last time I viewed this model in my headset (roughly late June of 2018) navigation was fine. Now, when I try to navigate the model (using IrisVR), the view in the HMD gets 'wavy' like I am moving through water. When I stop moving, things are fine. I know this model is large, but things were working at one point. I tried rolling the graphics card (NVIDIA GeForce GTX 1070) back as far as I could with no success. Any suggestions?
