Hello, a number of Unreal games seem to have this issue, and GPU providers don’t have solutions except suggesting to update the drivers

If it doesn’t work, you can disable DX12 by doing this: right click on the game > Properties > in the Launch options, type "-force -dx11"

And it should be good.

thank you for your help, the modified launch options fixed the issue for me. :)

Saw one video of the game and instantly fell in love. But my dreams were shattered by my 10+ old hardware....

Fatal error!

Yeah I'm sorry, the game was built with Unreal Engine and can be pretty intensive on the graphic card despite its simplicity (lots of models to view at once), so the requirements aren't as low as other games.

I manage to launch the game with the solution mentioned above, it actually works pretty good and no overheating, I really enjoy the game I love the hard challange its rare these days I get excited for a game.
