1. Well, if your game is the same as in the GIF below (1FPS, and yes, it's from another game by the dev...), then most likely you will have to save up for the next year and still replace your computer with something a little newer...
2. 500 MB is how much physical memory your computer has allocated for "main thread of execution" the game - quite accurate if you compare it with what the "Task Manager" shows and considering that the dev thinks that there are 1,000,000 bytes in a megabyte, and the Task Manager that there are 1024X1024 = 1,048,576 bytes in a megabyte.
3. fps: 0 - this for everyone... Is not a bug, but a featur - the dev just put a placeholder there for nowe, so that gamers don't measure their dicks, but play the game...
4. Glad I could help you...
