Hello @hpoonis2010 !
Thanks for the update! When the character freezes, have you noticed anything else happen, like the game switching to Windowed mode of potentially anything else not responding on the Task Manager?
By the looks of it, we'll need to take a look at your Msinfo and Dxdiag files to eliminate any possibilities that it's something to do with your configuration, and then report it to the dev team. As these files (Msinfo specifically) contain personal information, though, it would be best to contact us via our Help Website and attach the files, so we can look into the issue further. We've an article prepared about how to generate the files here.
