1.We tested some cases and found there is no big change before.

2.This time we installed the patch and tested all of the cases. The performance
of the most cases are worse than that without patch,(for exzample:case
unigine-sanctuary,reduced ~47%,Half_Life 2 reduced ~137%,....),and minor cases
are better.
