The Witcher 1 & 2 have received the "GOG Preservation Program" label. When I read this, I expect the program to run on current operating systems. Does this mean that I can now play Witcher 1 & 2 on macOS 15 and the latest processors?

What about macOS and Linux?

The GOG Preservation Program is currently Windows-only. Our priority is to preserve as many games as possible under the Program, before expanding to other operating systems.

Taken from the FAQ at the bottom of this site:

You can assume that on GOG by default, unless mentioned otherwise.

Don't worry, this "preservation program" is nothing more, than a marketing trick. And is unlikely to last for long, anyway. ;)

Not sure how this is marketing trick. It's just GOG saying they're going to update their older games that might not work on modern hardware.

There were talks on forums recently, that "Good Old Games" used to be a more appealing brand, than simply "GOG". And replacing original versions of games with remasters is the opposite to preservation. ;)

I think, their marketing staff has read those discussions and decided to gain some publicity before Black Friday and the upcoming Christmas sale.

So, numerous game installers have been updated with some low-effort fixes ( like LAA or configuration tweaks ) Which you can easily and safely apply yourself, spending some time on PC Gaming Wiki and similar resources.

I doubt, GOG would really invest into testing and fixing dozens of old games. Especially, if the solution is not already present elsewhere.

Of course, it is my personal opinion, based on observation and known facts. I might be wrong. :) Software. Windows 11 in particular. ;)

I both agree and disagree with you. They likely worked on this for quite some time, as I find it hard to believe that GOG could update 100 games in less than a month, judging from their track recorder. Unless you're referring specifically to the "Good Old Games" tag. I believe they are focusing on this because older games, such as Resident Evil and other classic titles they've released, have proven to sell very well for them.

However, I wouldn't be surprised if they decided to add the "Good Old Games" logo at the last minute. That said, it doesn't necessarily indicate that it's just a marketing gimmick.

Window 11 is still one of most used OS. 50% of steam users are using it.

Pretty much this. No, it's more of a "we actually test said games are working on modern OSes now" :P.

Let's hope this continues. Because more games working on modern hardware the better.

This statement is absolutely terrifying: We test and update the games so they work flawlessly on the most popular PC configurations!

The sane thing would be to make games compatible with as many systems as possible, old and new. Popular does not always means the best. Not only low-effort fixes, apparently they manage to break a few games already with their so called "fixes". If something ain't broke, don't fix it!

This "preservation" thing is becoming a problem, it's just like GoG galaxy all over again.

I don't understand how you may call Dragon Age Origins "something ain't broke" while many people have issues with it for example and the 4 GB patch as they call it is the one thing everyone recommends to be used. And also how is this a low-effort fix when it is the one thing you want 100% of the time. Nobody wants to deal with fixes when they buy a game and many don't know how to use these or instal them properly. Obviously they need to be extra careful with these fixes and not cause new problems!

IDK about Dragon Age Origins, i played it eons ago. I don't even own the gog version! I only read that people are having issues after the update, and introducing new bugs isn't exactly a fix.

Also you skipped the part about "there may be other problems with other games"

Well then don't give example with it while saying "If something ain't broke, don't fix it" when you have no idea how the game works and u don't even own it here... (It is one of the games you have linked as having issues after the new fixes). As for the new issues - let see how they handle it first!

(－‸ლ)

Well more reports are coming in, this clearly is not an isolated incident! And after a stupid statement such as: work flawlessly on the most popular PC configurations. You should be worried too.
