Microsoft’s Windows 10 launches on July 29 and GOG games is ready.  The distribution service and publisher reassured fans in a blog post on Wednesday that it has been testing its games and is optimistic they will work from the OS release date.

Although it did mention that some games might require a patch to “run smoothly,” GOG is hoping that fans “will make a near-seamless transition.”

The release of the statement comes after fans aired their concerns on the GOG forums.

“So far, things are looking great. We’re encountering very few problems and most of those are either resolvable on our end, or likely to get fixed as Windows 10 nears release,” GOG said in the statement. “In fact, many games that had issues on operating systems newer than Windows XP once again won’t suffer any hiccups on Windows 10.”

Compatibility is a big concern for current GOG gamers as Microsoft offers free upgrades to Windows 10 for some of its existing users.

GOG also mentioned that due to the OS still being a work in progress, “anything can happen until the release date.” Though it is confident in the transition and says GOG Galaxy users will be ready to get their game on automatically.
