hmmm ok. This game is a low graphics game so it should work fine on your computer with your specs…
If you don’t mind, could you run the game again — but this time:
open the folder containing the .exe in file explorer
Shift + right click anywhere in that folder and press “Open Command Window Here”.
In this windows CMD, run the game by typing .\bearcycle.exe and press enter
play the game until you get low performance
Copy the output from the CMD and send it to me.
It might be helpful, but no worries if this is too much work — I’ll try to add better log sending in the future..
