1:50:46vaualbus Q: Just as side note on that Nvidia fiasco you had. I found out that in my case I can get Nsight graphics to crash in the same way if I use raw input to get PS4 controller data. As soon as I remove the call that registers raw controllers, Nsight work. Any idea on why that could happen? Maybe Nsight is using something to intercept user input?
