When I trace an 64-bit app using CUDA Driver API in Nsight on a machine with RTX 2080 Ti running Windows 10 x64, I only see CUDA Context 0 on the timeline (the first context this app creates). I do not see other contexts for some reason (where most of the app’s useful activity (kernel calls, memory transfers etc.) takes place).
This used to work well on the same computer in the same version of Nsight (184.108.40.20697) with 1080 Ti (and earlier with 980 Ti too) before switching to 2080 Ti.
Tried drivers 411.63 and 416.34: same result.
