Oh goodie.

The hell is directional occlusion. xD

Ah improved SSAO, thanks.

Hmm, I thought I had a similar issue, but I just downloaded the new full installer and it loads fine. Not using an ssd... I'm not sure why the patch didn't like me though.

JudasIscariot: I'm redownloading my game backups spread out over time to lighten the load on my monthly ISP cap and to make sure I have the newest version of all of the games+extras and am not missing anything. The process I'm following is roughly this:

1) Visit GOG website in Firefox, view library, filter to see "Updated" games.
2) Select a game at random, go into the Galaxy client and bring up the download page for the game.
3) Download the main game executable, and any patches present if they update the game to something newer than the executable.
4) Download all of the game extras excluding anything for Macintosh or Linux that might be present, also excluding anything non-English.
5) Check if I already had a backup copy from previously, going all the way back to when games were bundled together and check all files and their contents to see what was added/removed or if I can spot any problems or missing files etc.
6) If the new download appears to be identical or superior to the old one, delete the old copy(ies) and move the new download to a new archives folder.
7) Proceed through list of all games flagged by the website as being "updated", then proceed from there with games that I have older archives of which are/were not flagged for updates but which I may have never downloaded yet since they were all bundled together, or which may have been updated but no flag/notification sent out, repeating step 1-6 for each game.

Along the way, I am making notes of any discrepancies, missing files, duplicated things and anything else that seems odd or possibly wrong. I am finding things such as a game including 2 or 3 copies of the MP3 soundtrack under different filenames however the contents of them all do not match. In some cases one or more files are missing from the ZIP archive and the current version offered from Galaxy doesn't necessarily seem to be the most recent version GOG has made available, or it might be missing files for example. I am noticing a number of occurrences like this with different games which I believe may simply be remnant bugs from the unbundling or other updates that have not yet been noticed by anyone and reported over time.

My question is: What is the best way to report these issues to GOG? Should I report them:

1) ... here in detail in this thread?
2) ... in the "What did just break?" thread?
3) ... to GOG Support via a support ticket?
4) ... in GOG's mantis bug tracker?
5) ... in a new thread in the game's official support forum on GOG?
6) ... in a new thread in the general community forum on GOG?

I should note that some of these issues do appear to be a bug or packaging accident of some sort, while others it is not completely clear if there is a bug/issue or not so it isn't necessarily a bug and might just need some kind of official explanation for the difference. I'm not easily able to determine them all on my own though so I need to mention it somewhere and just wanted to do it in a place that would be the most productive for GOG to comment on, examine and potentially fix, and with a way to follow up on each issue that turn out to be an actual bug. This might mean reporting it on the forums initially and then reporting it to support or mantis once a bug can be confirmed perhaps.

So far I've encountered 3-4 games with anomalies of this nature and am hesitant to delete my old backups and nobody ever notice there is a problem for a long time. I'd rather contribute my findings to try to improve the robustness of both the GOG download catalogue and my own local backup copies.

Thanks in advance!

Regardless of Judas's response, I'd appreciate it if you posted your findings (or a link to your findings posted elsewhere) here.

I hate to break it to you but you are already doing it wrong at step 1).

So many games had their flags gone AWOL that you can't rely on flags anymore. Flags are known to appear for Mac updates (which are not useful to most people) or not appear at all at random.

So if you want to make sure you have the latest version of everything you have to redownload your whole library.

Duplicates bonus : i suspect you speak most of the times about games which have been unbundled : umm yeah GOG didn't do the job properly, the only case (i'm aware) they fixed the issue was the might & magic serie. otherwise it's just a big mess. (without counting the excess of data to d/l for some specific games series)

A few games have some issues with their zip files : missing some jpg files inside an archive for example, the issue isn't new but i can't remember wich games... :| > normaly that's judas's job... i remember to have mentioned to him such issue, but i don't think those have been fixed (could mistaken though)

there's also an occasional bug which occurs with some installers, some of them have a missing timestamp signature....

As for where to report problem :

* Mantis tracker is for Galaxy , i believe (you should reserve this channel , only for an issue with the client itself , or games downloaded directly) -> But since i don't use Galaxy, i can't really tell if there's a difference between the offline installers + bonus with thoses avaible through your library (website).

* An issue with a new patch / installer (since those are the sames for the website / galaxy) : in this thread , but if this persists for too long , my thread : "the what did just break thread" -> in this case would thatbe what's still broken ;) . But the best advice is to fill up a ticket (and hoping some fix ....).

* For bonus; i don't think it would be a high priority and i don't even sure they still have the missing files :S.

FInally : the flags : well as pointed above , IT'S NOT reliable, as i said some days ago , what's the point of the changelogs with a broken system ... :/

erm , well i suggested to put hashes of installers + patches inside a text file (with the lastest date of the update -> the website library interface is clunky as hell......) , that would makes things easier..... > heck , even humble bundle uses this for each drm-free download. There's no update system, but at least it's reliable for the date & checking the integrity of the files downloaded (if it's done with the browser)
