slow graphics, no more acceleration

[dickreuter]

I installed windows 7 and everything worked fine. Suddenly graphic acceleration appears to have been deactivated (although there are no such indications in the control panel of my nvidia graphic card).

The system has become very slow and the windows no longer slide into the taskbar, although many other graphics effects are still present (such as transparent windows and 3d task switch with windows+tab keys).

I suspect the for some reason windows has activated its WARP system and is now no longer using my GPU but is using my CPU for graphic acceleration.

Any suggestions what I can do?

thanks
Nicolas

Make sure you install the correct drivers for your card and not the default ones win 7 installs.

I uninstalled them and reinstalled them and it doesn't have any effect.

Which Nvidia card are you running? You can find out by typing in the search box system information. It has to be a gs or an M card. A lot of resolution and other prolems have been resolved by torrentg. He can write a custom .inf file if needed. Or you can go to NVIDIA MobilityModder - DriverHeaven.net and follow the steps their.

Hey. Since that's a Vaio, you can follow this link to get the latest driver installed on your system.

Windows 7 doesn't have a "WARP system."
