yeah for laptops you`ll have to have a verry expensive one to run this game(or any new game) for desktops i think most people have a dual core 3.0 ghz or more..
Exactly where are you getting that idea from? Because no, most desktop users do
not have a 3.0 GHz dual-core processor or greater. The quality of graphics in comparison to the apparent system requirements here do not match up - you need to optimize the game's assets.
Just looking at your screenshots, I can tell that you also need to tighten up your physics properties (~13ms), find out why your game logic is taking so long (~16ms), and find out what Blender is calculating as "Overhead."
For a game running at 60 frames per second, you only have approximately 16ms total
per frame to do everything - about 33ms for 30 frames per second.
