Hello I pre ordered Alfred Hitchcock - Vertigo - Digital Deluxe Edition but I don't find the pre order bonus anywhere. Before installing the game with GoG Galaxy it showed in the Extras => Goodies the option to download the pre order bonus but couldn't download it, it indicated 0 MB. Now it doesn't even show the pre order bonus. Where can I find it?

Hello. I still don't have the 2 avatars as bonus of the pre-order, did others players that pre order received or not the bonus avatars?
Also how to use the in-game filters? I installed with GoG Galaxy, is it auto installed with the game?
Thank you.

I bought the game after release so I cannot speak of the pre-order bonuses.

But I think the in-game filters have not yet been added. There's a note in the Digital Deluxe Edition store page that currently reads: "In-game filters DLC is coming soon!"

Thank you!
Also the pre order bonus is available now to download.

The Steam version got a patch with bug fixes which also added the visual filters for the Deluxe edition, as an in-game option.

- Script and subtitles fixes
- Audio & volume balancing
- Correction applied to the blackscreen issue, causing an infinite loading on some configurations
- Deluxe filters are now available for the owners via an In-game option (on the Main Menu and Pause menus)
- General animation improvements
- General Illumination improvements
- VFX Improvements
- SFX Fixes
- Voices & Lipsync Fixes
- Multiple bug fixing

I don't think this update has made it to GOG yet -- at least I cannot see the deluxe filters (I have the deluxe edition here). Hopefully, it's coming soon.

Today when launching the GOG Galaxy client, my game (Digital Deluxe Edition) got a small update, and now I can see theoption to enable the in-game visual filters!

The above changelog refers to the patch from December 23 (which is also on GOG). There is no newer build on Steam as you can see here:

As for the Deluxe Filters - I had to do an account refresh to make that DLC show up in my library on the webpage. Unfortunately the download link leads to a 404 page. I was able to download the DLC by changing "downloads" to "downlink" inside the link address. The DLC still doesn't show up inside Galaxy though. xD

For me it shows up on the web page (for my Games on GOG) as an offline download under "Download offline backup game installers" way down in the list, under "DLC installers". The link works as is for me.
Also showing up on GOG Galaxy, since yesterday that I last checked, under Extras -> in the list under Offline Backup Installers, and in the "Manage Installation" -> "Configure..." dialogue as a checkbox to enable/disable (I have not tried to disable it yet :P -- I want to play in B/W! ).

Ok, i tried again and now the link on the webpage is working fine but still nothing inside Galaxy, even after a restart. xD
Screenshots attached.
