Thanks for the links and do u know how to use them?
A) simple answer: you cannot play PS3 games on your computer. Firstly, you would need a blu-ray dive (which you may or may not have), and secondly you would need the necessary bios, firmware, and codecs to get it running. Then, after that, you would need an absurdly powerful computer to run the games. So powerful, in fact, that I don't think at least 99% of the worlds computers could run it (console emulation is a very difficult process for a computer because of the completely different architecture). This is all also assuming that someone has actually managed to develop a working PS3 emulator, which I also seriously doubt.
To run 3d games on your computer, you need a graphics card that supports 3d graphics, which you could probably have found for the last 10-15 years or so. Direct X is also probably necessary, as is RAM and a computer that is more powerful than a Pentium with a 200 Mhz processor (no numbers, just a Pentium). If you have all this, then maybe you're missing some games that support 3d? Have you installed it?
C) I can't tell you how to play a 3d game unless I know what it is! Tell me that, first.
D) Maybe you should try playing the games from your desk? It can be hard to see from inside those tiny boxes.
Edit: Just to correct the poster below me a little, I think you might be looking more at around 4-10 gigs of ram, maybe a 3-ish Ghz quad-core processor, and a state-of-the-art 512 meg graphics card.
Let me put it this way - around 2.0 GHz (single core), 1 gig of ram and a 128 Mb graphics card will get you emulating a NINTENDO DS smoothly. Think about that, while thinking about the difference between a DS and a PS3, K? Unless you don't like too many fps. I'm quite partial to it, myself, but like they say, each to his own. Some people just prefer slide-shows, I guess?
also The PlayStation is a completely different platform than PC (Win, Linux, Mac). Both the CPU (Cell Microprocessor) and the GPU (NVIDIA RSX) are using different architecture and instruction sets than the PC platform.
