LD_PRELOAD="radv_force_pstate_peak_gfx11_dgpu=false -force-vulkan -USEALLAVAILABLECORES" %command%
LD_Preload and these other commands are my catch-all solution. I don't know which performance issues it had, I just inserted all of these commands so I don't have to tinker. Before these commands, the game ran very poorly and even crashed on launching. I'm using Proton 9.0-4, older versions did not work.

I have tried multiple ways of getting the game working on my dedicated graphics but it won't run on it.
Runs on the integrated graphics card
The game doesn't want to run on the dedicated Graphics card no matter what I tried
I have tried getting it working but anytime the game launches it uses start_protected_game.exe
to launch EAC which does run on the dGPU but then when the Deceit2Game-Win64-Shipping.exe
game launches it seems to not care about any environment variables setup, so can't be played on a gaming laptop. Otherwise it might work just fine if you don't have a gaming laptop.
"Anticheat kick: Anti-cheat client protection not active (NullClient)" doesn't matter what version of proton I use
I start the game without any proton . it just runs in Steam naturally.

With Proton 7.0.6, the game opens on the splash screen, but it doesn't go any further
Using Proton 7.0-6, I can open the game on the splash screen, but when I click "continue" the game says "Invalid auth module".
I could run and play the game just once with Proton 8.0-5. Then I closed it and tried to run again, now with no sucess. With this and other versions of Proton, the game doesn't go beyond EAC screen.

menu background animations jittery and laggy
switched to older version of proton and it ran almost perfectly fine, loaded faster than my friends on windows.
Saw loading window, couldn't launch

This game runs great on Linux
I have not had any of the problems mentioned by others here. The game runs perfectly.

fps 50-300 im durchschnitt google english: FPS 50-300 in the mean

Way too unstable
Extremely frequent crashes, about 10-30 seconds into a game
(unable to fully test due to the frequent crashes)
This was tested during the Deceit 2 Playtest beta, there was a lot of crashes, once in the menu after looking around a bit, and a few times quickly in game, often after completing a task. Currently unplayable
