Confusion on Performance Tuner Log & Graphics Drivers

[Anonymous]

Model: Thinkpad W520 with Quadro 1000M

Driver installed: v268.44

Application: AutoCAD 2012

Obviously, the driver is not up-to-date. The reason why I didn't update by ThinkVantage Tools or download a newer version from Nvidia is, this version is certified by Autodesk according to Lenovo official site.

Unfortunately, it seems that AutoCAD does not recognize the card with this driver.

The Performance Tuner file is up-to-date.

Well, the fact is I reinstalled the older version as I found it on Lenovo. It was possible to manually enable the Hardware Acceleration before with the latest version. I expected Hardware Acceleration could be enabled by default if I install the certified version but now it even doesn't work al all.

So please help.
