12.5MB log, mostly spam from ntdll that causes a lot of lag in-game, in my
opinion

DXVK is not the issue as far as I know, since it doesn't throw any error, NTDLL
though, spams like hell, since the log is 12.5MB and that makes the game laggy
very frequently, sometimes my FPS dips to 15/20 for various seconds (and it's
not the CPU throttling lag, since I disabled PROCHOT response and undervolted
the CPU)

That's the proof, here you can see it in action, notice the lag, especially
when I disable RTGI so, more FPS = even more noticeable stuttering

This appears to be caused by the RTL_CRITICAL_SECTION_FLAG_DYNAMIC_SPIN not
being supported.

Affect plain wine as well.

Well, the proof of that diagnosis is that WINEDEBUG=-ntdll fixes performance.
Does it?

Strangely enough, it doesn't, it could be a DXVK issue
"D3D11Buffer::QueryInterface: Unknown interface query" spam in the log file,
still how is RTL_CRITICAL_SECTION_FLAG_DYNAMIC_SPIN going to be supported?

All right, I ran another series of tests.
Game will open much faster with -ntdll and the thing that I said for DXVK,
forget it, that isn't the problem.
Apparently the major issue that I have is coming from the HD Texture pack, when
I disable it, most of the freezes are gone, still sometimes, the ndtll spam
causes me a few stutters

Okay, but do you get a measurable difference between +ntdll and -ntdll, with
all other factors remaining the same?

It's possible that logs cause performance problems, but it's generally more
likely that they coincide with something else that is causing performance
problems.

Note also that DXVK is not supported in this bug tracker; if you encounter bugs
while using DXVK please file a bug report with the DXVK project.

every freeze is gone with -ntdll and the game will load much faster

I have WINEDEBUG=-all but game still have fps drop spikes. It drop FPS every 3
seconds no matter what I'm doing: no mouse move, looking at water, looking at
map or even using PHOTO mode, when scene is static. I tried different wine
versions winehq 7.20, lutris 7.2, proton 7.0-4 (game wont start)

I've tested different versions of the game. All of them has fps drops. Running
game (same binaries) under Windows has no issues.

Also I've tested WINEDEBUG=-all,+file channel to see if here is intense file
IO. But noting comes up. It not using any IO havely.

htop showing CPU usage increase from 350% up to 450% for FarCry5.exe process
for moments of fps drops.

Issue happens during all game content starting from initial game video (after
intro), during first mission, even in PHOTO mode and uring benchmark.

I tried to disable WiFi - no changes.

Sometimes game works fine, very rarely. I can play  few mission and without
lags. Mostly first few missions. The rest of the game I never seen runs
smoothly. I did clean all wine related files inside prefix or reinstall the
game compeletly or drop ~/.cache/*shaders* files but no idea what is causing it
or why game runs fine sometimes.

Hello,

You may have a different issue.

How much system memory (RAM) do you have?

Regards.

I have a lot of ram 16gb. and 5gb goes to video RAM (it dynamically shared
between RAM and VRAM as I know).

No other games lagging like that. Even Far Cry 4, Doom Eternal works fine. Also
Windows works at Ultra settings with out any issues with 40 FPS. Only wine
stuttering.

Just in case, all logs and kernel versions.

My guess is - some wine methods are not optimized. When game calls a lot of
those methods in background it slows the game.

For example: the game Path of Exile works bad with winehq and with a lot of
monsters drop FPS to 0, game stuttering a lot. But using lutris wine I do not
have this issue and play game no problems even with a lot of monsters on screen
lutris do not drop FPS. I guess some intense IO operations were optimized under
lutris wine.

I tried lutris wine with Far Cry 5 but no success, same lags.

Another possibility: since those lags not related to file operations (I ran
+file) and lags persist during PHOTO MODE (when no physics and quests
calulated) and during in-game video it could be Far Cry 5 EasyAntiCheat service
activity.

For example this EAC trying to scan binary for injected libraries and doing it
using not optimized / slow wine methods. But I also tried to disable EAC using
hexedit instructions from PCGaming web site but no luck - lags are here. Who
know it maybe still trying to scan.

If you disable the HD texture pack the problem will go away, the problem is:
why?
It doesn't even fill my VRAM, something is clearly wrong.

I do not have HD textures installed. But turns out I had to use
proton-tkg-7.6.r12.g51472395-x86_64 (wine-tkg) to make problem go away!

After completing the game Far Cry 5 (a lot of hours without any fps drops) it
starts stuttering again even with proton-tkg-7.6.r12.g51472395-x86_64. I tried
to restart PC and changing wine versions... Nothing helping. I guess it is game
protection (anti-cheat or DRM) issue which happens periodically. Far Cry 6 or 4
works fine, never had this issue.
