Recently, I have updated cuda from 10.2 to 11.4. I noticed that the performance is over 10x worse with the same application. What could be the reason?

Most common reason for this kind of observation: one is a release build, the other is a debug build.
I had both compiled using Release.
It could be a code generation problem in the compiler (nvcc
).
