This didn't work for me, and it's so annoying. I tried disabling anything having to do with blurring and restarting GOG Galaxy between settings. Nothing worked. My eyes can't focus on anything after looking at that interface for a few minutes.

Edit: Even though I'd set FXAA to off for GOG Galaxy without success, I tried disabling it in the global settings. This worked, which leads me to believe that it's some other program's setting that needs to change. I couldn't change the setting for Chrome though, as it says FXAA is unavailable for it. So what could it be?

THANKS SO MUCH!!!
Worked for me too. Disabled FXAA in Global and it worked....

Cheers

Ok found issue with Gog Galaxy and Nvdia drivers about blurry image.


STEP 1
Start Gog Galaxy
Its Blurry.
Close it, Exit it.


STEP 2
Open Nvidia Settings Control Panel.
Click on Program Settings
Click Add
Sort Recently Used
There will be Galaxy Client Helper Application.
Select Add Selected Program

STEP 3
Set FXAA to OFF in Galaxy Client Helper Application

STEP 4
Launch Gog galaxy from your shortcut


Whatever you do to original Gog galaxy application it doesnt works cause it seems that you have to manually add program and it will give you new link. Happens with all apps :)

This is what I have been trying to tell people FOR WEEKS! I thought it was my graphics card!

Thanks masterring! Your step by step advice fixed the issue! Thank you!

Thanks,yourself! This worked like a charm, so now I can have default global settings again.

The Nvidia Control Panel fix worked for me :)

Thanks

Fixed,


Thanks.

Wow thanks a lot! I was going nuts about this problem. I already tinkered around with tne nvidia settings but nothing seemed to have any effect!
Hier hint with the manual addition of the exclusion rule fixed the issue. The reason is:
the "build in" GOG Option in the nvidia driver expects a "galaxyclient.exe" while the "true" exe is called "galaxyclient helper.exe".
THIS is the one that gets added to the list of exclusions when you do it the way you described it and *tadaaaaa* the fonts are crystal clear again.

Just want to say thanks - solved my blurry problem. Still have a furry problem but I'm hoping the meds work for that :)

Just want to thank you like everyone else. This solved my problem in 2020. Surprised they haven't fixed it by now but I'm glad I found your solution!
