x64 mode start

Can somebody please remind me how/where to place an initialization script for x64? I used to know how to do this but can’t remember now.

/x64 in the command line.

what is the file that I need to edit? Where in file do I place it?

I use the steam version and I simply right click my grim dawn in steam library and then go to properties, in the general tab is set launch options, in there is where i put /x64.

Not sure if your using GoG version or not but there is also a x64 folder in the grim dawn install folder which has exe to run x64 (make shortcut)

Cool, ty for help.
