Out of Video Memory - GTX Titan X

I had this same issue.

Maya would crash, Unreal would crash, and Photoshop would crash, especially if I tried to multi-task.

What I heard worked for other people:

Match your virtual memory with your physical memory just to give yourself some buffer room. (probably more for placebo comfort than the real reason I was getting the error)

But the real reason and fix that worked for me:

Remove any unnecessary screens and 3rd-party software managing screens. I had a VR headset plugged in that was the culprit for my issues, other people had screens that needed software updates. My headset was plugged into my motherboard instead of my actual graphics card too which was tricking software into thinking the motherboard was the GPU of choice. Also make sure to update the drivers for the headset/screen.

I hope this helps anyone that runs into this same issue.
