I'm having the same issue with 1.1. Installing on to a Samsung 860 EVO SSD 1TB with 3/4 of the drive empty and it took over an hour at applying patches to go from 92% to 100%.

No issues with this before 1.1. STEAM, Origin and EPIC have had no trouble installing or updating games on this SSD. Meaning the issue is either with 1.01 or Galaxy.

Wonder if the temp folder where the decompressed files are temp stored is not a problem have you relocated that from the GOG program drive ?

Same here. Stuck to 92% after changing temp update folder to HDD. Restarting GOG Galaxy didn't help. Same story, from 65% to 92% in a few minutes and still 92% with 100% loaded disk.

from 92% to 100% in 23 minutes... what a garbage

What Antivirus are you using ?

Microsoft Defender

I keep seeing posts that say have enough space and put it on an SSD.

My patch says 1.1gb downloaded, applying patch, 92%. It has been saying that for 16 hours.

My machine has an i7-5820@3.3ghz, 64gb ram, two m2 SSD drives and a 5 TB drive. Game is installed on the standard drive that has 2 TB of space open.

Should this really be taking this long on my machine?

Mine downloaded in under 6 minutes and I was playing the game patched in about 8 minutes total.

I don't know if this will help, but i had the same problem and kept closing Galaxy and restarting it, including going into Task Manager to make sure it was completely closed. (It wasn't.)

About the 4th time I did that, I realized Task Manager said Cyberpunk was running too, even though it was consuming zero resources.

So I closed Galaxy and all its associated processes, closed the phantom Cyberpunk, then restarted Galaxy, and voila, suddenly it said the game was completely updated and ready to play.

I hope that helps you or someone else because, yeah, it was very frustrating to be locked out of the game. Cheers.

Sorry to necro this but this helped me with the 1.23 patch tonight.

yup. it also criples my pc. gooood job. after one year i felt like to give to game an run. well i canceled this patch to enjoy something else ... maybe ill try to "apply" your patch some next time... srsly it is 800mb and it is installing as fast as turtle moving... with all four leg's broken :-/

The method is basically depending on having extremely fast buffers (meaning M.2 Gen 2.0 + tech ).

So people with HDD / SSD (2.5mm SATA3) are basically screwed over.

The funny thing is that most patches are essentially bundles compressed. Decompressed when downloaded. That's the standard thing. The applying patch can happeen while download or after. The fact that they decided that copying all game files into a temp file, then pasting the updated ones on top and then copying them back to original installation folder is the reason for all this mess.

It's really frustrating that this method still considered a practice, when methods like patching while downloading file per file or overwriting updated files from patch manifest after download are out there.

Hope this gets fixed at some point.
