text: i was running sims2 and then an error message say that i need a directx 9.0c compatible graphic adapter ? what does that mean can you help me please ! the problem with sims 2 is that the graphics card must be direct x 9.0c 'hardware' compatible, some are not!!  ok. click start, run and type dxdiag, this little program will give you details of your hardware (relating to direct x). run all the tests and see if anything fails. also make a note of the date of the graphics card software, then visit either ati, nvidea or the manufacturers website and download the latest video drivers.   if it still fails you need to buy a new graphics card, ask for a direct x 9.0c compatible card. from experience most cards manufactured in the last 18 months should be compatible.  another tip while playing is to shut down everything else in the background, including your virus scanner (don't forget to turn it back on if you go online)
