I upgraded yesterday and decided to try all of my installed games today. So far, only the Witcher gave me trouble. I got the Big white warning box "WARNING, MINIMUM SYSTEM REQUIREMENTS NOT MET". It was strange since I was in the middle of a playthrough when played on Windows 8.1. I play on my Nvidia laptop with a dedicated card and haven't had this problem before. The global graphic settings for my computer are set to the dedicated over integrated.

The Windows 10 upgrade was the only change made recently. I did a little research about this and I know this was a problem for some people on Nvidia laptops in Windows 8.1. I'll uninstall the game for now, but I want Gog to know about this problem. Since I never had this problem in Windows 8.1, I could only assume that an update will come out to fix this issue.

Did you check the graphics driver? I believe it is best practice to install hardware drivers (especially graphics) from the manufacturer and to avoid using hardware drivers supplied my M$.

Now that you mention it, I actually just got a driver update. I'll reinstall and give it another go.


Edit: After the first post and before my second one, i received a driver update for Windows 10 through The Nvidia experience. I just tried the game again, and was able to launch it. However, I got some strange settings for textures in the advanced menu. And when I launched a game to test it out, it crashed my computer and forced a restart.

Again, I have plenty of other games to play at the moment, so I'll wait for a fix from either Nvidia or Gog.com

Yeah I just upgraded to Windows 10 and I'm getting that same exact warning message now.
But I do have some graphics driver update downloading through windows update right now, so we'll see what happens after I get all that sorted out.

For me it works now.
With windows 8.1 I had the minimum spects problem, but now with windows 10 I don't have any error.

This may or may not be related but I was having problems with some games after upgrading to Windows 10 until I did a clean installation of the most recent nVidia driver for Windows 10 and then restarted my PC.
