My problem is this... When I updated my msi gt60-one (ivy bridge processor) with a new nvidia gtx 970m vcard, for the first week it works like a charm.. then I re-format and made a fresh install of windows 7 .. All drivers installed successfully.. But when playing games or any 3d app games, intel 4000 works as the gpu..
Both intel hd4000 and 970m nvidia drivers was installed successfully... but the 970m not executing on 3d games... Is this related to bug of hd4000 drivers or optimus drivers not switching to 970m when 3d apps enabled? I selected on the nvidia control panel the 970m during 3d games though... Please help thanks
