Some games spam the log and fail to run at full speed

I've noticed that Worms United and Action Soccer continuously log this to the console when in-game. They work fine in the menus but when being in a level, there's a massive amount of logging going on:

This seems to cause both games to run very slow (like 10-15fps) on a Ryzen 9 3950X even with cycles set to max (Settings->Performance Options->Emulated Performance). They work fine with the original Dosbox as well as Dosbox-x (and the aforementioned max setting), which makes it look like an issue with this core.
