Made even a separate mod for it now

Actually even better solution:

modded class PlayerBase
{
	override void AfterStoreLoad()
	{
		super.AfterStoreLoad();
		GetStaminaHandler().SetStamina(GetStatStamina().Get());
	}
}

So just this is really needed for the Stamina to get loaded from the PlayerStats since seems like PlayerStats aren't loaded before the Init but they're loaded before the first Update cycle. There's not a single m_Player.GetStatStamina().Get() in the StaminaHandler to actually load the Stamina from save. Why is it even build like this? Also there's basically three times m_Player.GetStatStamina().Set(m_Stamina) calls because SetStamina also calls it though SyncStamina, which there are two in the Update.

I've now gone through installing the Fanatec drivers from 412 up to 447 and 450 current versions. It's now not crashing if I've my wheel plugged in. But it's crashing now if I've my ClubSport V3 Pedals plugged in, so it went to completely opposite now.

Here's thread and post by me and looks like Fanatec has tried to see where the issue is for some time.

Also it happens in DayZ. Somehow had the wheel at Xbox mode and not in PC mode first when I tried.

Also if I remember right this didn't happen in the 2022 Summer-Autumn, so some update happened after that.

Still there even in Experimental. Some examples

What about if the focus is lower or you couldn't do it at all except when you walk or stand still. That way you could better focus when you go slowly. Focusing should be hard when you move especially sprinting.

Hmm should've do collection of all hard coded keybinds? I've noticed some inventory actions are hard coded like dropping items (G) and there were some others also. Can't bind Inventory to good old G for that reason... Need to check later more if you aren't faster.

Likely related to the negative mouse acceleration that they have in the game? Very noticeable how bad it's when you go in vehicle turret.

There are some other keybinds that do the same. Here's the list I know so far:
CharacterNextFireMode
CharacterNextMuzzle
CharacterWeaponManualSafety
CharacterWeaponADS
VehicleADS

None of the mouse things can be set in-game. However Mouse Button 4 and 5 are supported already which are button 3 and 4. They just need to fix the in-game binding in the menu. Alternative way now is to edit .chimeraUserInput.conf file. When you bind something in the keybind you want to set, it appears there.

Workaround until fixed for all bindings is to download the tools and edit the .chimeraUserInput.conf file. Need to bind something else first for the specific keybind to appear in there:
