Yeah a patch was released via LIVE, about 260 MB and it re-enables PhysX for the retail version, adds some benchmark mode and seems to allow ATI users to enable AA from the options launcher, probably touches the main EXE so a trainer update would be needed for it to work. (Bit uncertain as the game won't be released here until the 18th.)
Version 1.1 of Batman: Arkham Asylum came out today. It is the Physx add-on by Nvidia. You guys do great work and I am not expecting a trainer to be released immediately, but is there going to be a trainer for this version?
I didn't realize, but it seems there are already people asking this... my bad.
Oh well it happens. I aint worried, I expect to see a v1.1 trainer up in the next few days if not sooner. Then I will be sitting in my beanbag chair playing some Arkham Asylum while listening to Batdance by Prince.
