Unsupported video card?

@ashleigh1991  If you post the version number of your game as described, that will make it clear whether you're running the LE or not.

According to config.log though, your graphics card is in fact recognized by the game.  So there are a couple of possibilities here.  One is that you're looking at an older version of config.log, one that the game isn't using anymore.  The fastest way to find out is to launch Sims 4 once, quit, and check the date on the file.  If its last modified date updates to match when you launched TS4, then it's the correct file.

Another possibility is that your options.ini file is corrupt.  You can test this by deleting it (it's also in Documents\Electronic Arts\The Sims 4) and letting the game create a new one.  You'll need to reset all your in-game options, but the new file shouldn't cause any problems.

It's also possible that there's (still) an issue with the graphics card driver, or the card itself, and that sometimes, but not all the time, your system is unable to use the card.  The next time you get the unsupported card message, please copy and paste the same section of config.log that you posted here.  If the game isn't using your card, this info should make it clear.
