Thank you. Can you also take a look at D89832 <https://reviews.llvm.org/D89832> 
which extracts CUDA version from .h file, when version.txt is not available?



================
Comment at: clang/test/Driver/cuda-version-check.cu:13
 // RUN:    FileCheck %s --check-prefix=UNKNOWN_VERSION
+// CUDA-11.1 does not carry version.txt file. Make sure we still detect it as a
+// new version and handle it the same as we handle other new CUDA versions.

Oh, Windows... That explains the disparity.
Thank you for testing the patch there. Could you also give D89832 a try?
