Hello @Cxpher, please disable uplay's overlay, then add PROTON_LOG=1 %command% to the game's launch options and drag and drop the generated $HOME/steam-$APPID.log into the comment box.

Hi,
How do I disable uplay overlay?

I need to kill upc.exe and then the zombie process comes to live and starts the game.

However..

Three minor issues:

1: I can't get rid of the box in the upper right corner "Press Shift+F2 while in game to activate the overlay" while in game. Can't disable the Uplay overlay unless anyone has a better way? The Uplay client on the desktop via wine won't respond to any clicks

2: There is a black square appearing at the center of the screen at the beginning of each fight which fades away quickly. So it doesn't interfere with the gameplay

Uplay works fine for me, I right clicked in that window

went to settings and disabled Uplay overlay and as much other options as possible, like notifications, friends, etc. except Cloud saves. So, no Uplay box on my screen.

Game also works fine so far, including Steam controller, with the exception of same black square as @Cxpher reported

Attached is log with black square

Hi guys,

I tried right clicking on this window and going settings.

That's where I wasn't able to interact with the Uplay window. Going to
Uplay in game options does not give me the option to disable to overlay.

Could be one off. I'll try later and see if I can do it.

As for the black box, that's definitely not normal. Playable but it's
noticeable.

No such window shows up on my end.
Game prepares for start for a while but closes eventually.

You have to kill upc.exe. It will auto restart and start uplay and CoL.

I actually changed versions and verified cache (some random actions)

For some reason it seems to work now. Uplay does show up correctly, I can log in, the games show up and I can play :)

Disabling uplay overlay works.

Only thing left now is that black box.

CCxpher 2019-06-16 github

Black box still appears at the beginning of fights in 4.2-7. Should i open another bug report for that?

Oomicron-b 2019-06-16 github

@Cxpher no, the policy is 1 report per non officially supported game

Uplay don't becomes a zombie process for me and i don't saw any black boxes at beginning of fights, but i have a little bit crackling sound ingame and fps drops.

Comparing D9VK with Wine D3D9, I noticed that D9VK uses much less CPU resources: htop shows 200% CPU usage with Wine D3D9 and 140% with D9VK. Framerate with D9VK is generally 45 FPS, can reach 60 sometimes. With Wine D3D9, framerate is around 30, on very rare occasions reaches 50. I wonder what is the CPU load and frame rate when playing on Windows.

There is one difference I found: Aurora is different using D9VK, as if a different filter is being used. As Aurora's model is the only 3D model, it seems this difference is exclusive to Aurora. Enemies are the same, the backgrounds are the same: at least I couldn't find any any differences. The following images are cropped to make the comparison.

About UPlay, after setting to save the log in credentials, it opens the game directly, working as intended.

Edit: I did some tests on Windows. I stopped in one place where I noticed Child of Light was running at 60 FPS with very high GPU load (94% was the minimum observed) and around 25% CPU load (the equivalent for htop 100%, considering this is a four threads processor). It would very rarely go down to 57 FPS, but kept nearly all the time at 60 FPS. That same place on Linux caused a htop 140% CPU load with 100% GPU load and around 45 FPS. I believe this gives a reliable picture of the current performance impact.

There is the advantage that my gamepad works on Linux (including vibration) but doesn't on Windows.
