I checked out and built the 4.26 release on ubuntu 18.04. I have nvidia drivers installed. I can create new projects, but when I open any of them, I immediately crash with “VK_ERROR_DEVICE_LOST”
I have a GTX 1060 which should be enough, and I can see from the logs that it’s picking the nvidia card, not the integrated graphics on my laptop.
Any advice would be great, including how to force it to use lower resolution or OPENGL drivers or something. (should I be using 4.25? I want to work on oculus, so it would be nice to have the newest code).
Thanks for any help.
