I get this in FS2 on OpenGL when using an on screen display for assurance of my graphics card fan speed and GPU temperature. With VULKAN the display looks fine but it crashes with anything above the lowest graphics settings. Presumably the O.S.D. sits high in VRAM which causes a problem in a 2GB card.
The CPU-GPU balance is distorted by this phenomenon, 100 and 85 percent is more usual (a more powerful cpu would be desirable).
