I use Resource Monitor (type it in the task bar search box) to monitor my memory usage.
While using the Crystal light, I can watch the commit values and the working set values for MS2024 continuously rise and my free memory continuously fall (goes to a low of about 300 MB) followed by a crash with the DXGI…CALL error.
I did notice that if I go into 2d when the memory usage is increasing, then go back into VR, the values will stabilize and I can then complete the mission without it crashing.
