Many people have described stability issues with the patch, so you might want to be cautious.
*edit* from shacknews:
"Ubisoft let us know that the Far Cry 1.2 patch released a few days ago has been recalled. According to the publisher "Far Cry patch 1.2 has shown unexpected behaviour on specific hardware configurations. These matters are mainly due to incompatibilities with several optimisations brought lately to the code, with the intent to please a large number of users". CryTek is working on a fixed version of the update to be released "as soon as possible"."
