I've had no problems running it on Windows 7 Pro, not sure about Windows 10 Pro. I'll admit I installed it a couple of years ago and stopped to play other games and forgot about it lol.

I don't own the Home versions of either OS, so can't comment there.

I also run it on a gaming rig with a 1080 card and 16gb ram, if that helps.

I've run it without issue on a ThinkPad X230 on Windows 10 Pro and Linux (via wine) with no problems. Note that there have been a lot of threads, recently, with people complaining that GOG has not given them a multiplayer key with their purchase. I don't know whether that has been resolved?

There is a known issue with stutter or animations being out of sync after a while, the longer the PC has been left running or something, which can be fixed by rebooting the system, or, more reliably, by dropping the .dll from the "Jade Empire Stutter Fix" into the game directory (it works for NWN2 too). No idea where to get it currently though. The links in threads on this forum don't work anymore, so you'll have to google it.

Apart from the stuttering issues mentioned above, there's also a problem with changing the resolution, but it has a simple override. You just need to switch the game to windowed mode, change the resolution and switch back to fullscreen. And that's basically it. :) Besides that the game runs like a charm.

Thank you all. I have just bought it and so far game runs very well. First I have to finish the first game but it is good to know that 2 runs well. Speaking of resolution, minimalazing the game and switching the resolution then didn't work but I just changed the files and now NWN2 runs at 1080P :D

did the game come with keys for the multiplayer?

I don't think so. I think that if you want to play multiplayer you can use some software like gameranger.

No, your keys should show up on the website when you are logged in. You go to the menu with your username and click "Games," then search "Neverwinter" if you have lots of games in your library. Click on the game in the list, then select "Show Downloads," then "More," then "Serial Keys."

In the case of NWN2 I think you'll need to either direct connect to a server or install the NWN2 Client Extension (https://neverwintervault.org/project/nwn2/other/nwn2-client-extension) to view lists of servers, as the official server is offline.
