Thank you for playing!
I guess it needs a dedicated graphics card, not the usual intel integrated ones. On a RTX3060 it runs with 150 fps. Regarding the size, 93% of the game are textures. I could reduce them but it would make the game uglier, and I'm not sure if it were much faster then. I will test it with more configurations and write the minimal specs into the itch page.
I did the game alone but I have a little experience because this was not my first Cyberpunk Gamejam and I'm planning a bigger Cyberpunk game anyway.
