I believe it's a weird bug in the game, not a compatibility issue.
Is there a specific numbers of enemies that spawn in seemingly endless groups like targets?
What I mean with this is that for example I think the amount of enemies in the Egypt boss battle in XXL is around 35000 which you can see in the editor, but ingame there is no counter for them and they seem to spawn endlessly
Not sure, this needs to be checked, but I guess they might be infinite.
But in XXL they are not, I saw that in the editor
I already killed 100000 Romans in LuckSore in the green target room, so I guess they are infinite
Most likely an absurdly high number
Note that although it is not done by the devs, true infinite fights can be achieved through the games scripting
How can I fix screen tearing in this game?
I get it when moving the camera horizontally
The game has no VSync option in the settings 🤷♀️
Maybe you can force enable VSync (for example in the Nvidia control panel, or any third party tool)
or run the game in windowed mode, that might minimize the tearing
Yes, windowed mode should do it
There is significant screen tearing as well when i play fullscreen xxl, but it's gone when i use windowed.
not sure why that is tho

Probably because in windowed mode the frame has to pass through the DWM, which will draw a single frame in its whole to the desktop
