Blender game Issues

Ok so well,i am using the blender game engine and i am currently working
on a racing game.how well these 2 game engines work when it comes to rendering a game and which game works smooth on every pc and still delivers the graphics.
!!!Any suggestions to How the Blender game engine wroks smoother on other pc’s.!!!

The thing is that if i make a graphical game on blender i am afraid that
it will crash and that this will take too much performance if i render a
Graphical game like De-Ascend.

What “2 game engines”?

If you want to ensure that a game will work smoothly on multiple PCs, then pay attention to your framerate, optimize well, and have other people test it out on their PCs so you can get an idea of what needs to be worked on. My computer, for example, is pretty low-end at this point - the graphics card is fairly old, and the CPU isn’t very fast anymore, either. I have just 4 GB of RAM (Even a basic new desktop would have this amount of RAM or more). The point I’m getting at is that with this computer, I have a pretty good idea of how my game will run on other, more powerful computers.
