GTA IV with Nvidia Optimus (nvidia geforce gt 525M)

With the stable drivers the new Geforce 500 and 500m series with Optimus only see less than 100mb available graphics memory and have horribly slow texture loading as well as shudder, I solved this by completely uninstalling current nvidia drivers (there is not yet any official release so the drivers should be manufacturer) and installing the beta driver taken from www.geforce.com

This fixes all issues with the game and now my 525M can run the game at highest settings with no problems at all. Hope that helps some people.
