It's too memory hungry. Needs to be optimized to take less memory,  because windows is a memory hungry operating system, and this game cannot fit within 5GB of available memory.

This is on startup, btw. The main menu should not be taking this much, and loading the entire game at the start isn't feasible on most systems.

Edit: I'm assuming there's a main menu, cause I'm never able to get there before I'm forced to end the program.

same issue, i have a laptop with 16GB of memory with around 12 free at any time yet the game runs at less than 10fps, couldnt play for more than 15mins.
