Hi I recently purchaced a M17xr3 with 2730qm with 6990m. I thought something wasn't right from the start as gaming performance was realy bad. I then ran 3dmark Vantage to compare with this thread. My scores are P6827 GPU-5826 CPU-18k. I done all the basic checks. Plugged in to PS set power settings to performance. Checked graphics switching is set to ati GPU. Installed latest drivers(from dell). I know that the Discrete card is running because when i set it to integrated graphics performance drops even more. Games run OK but if i turn on AA on to even 2x it is unplayable. Is there anything else I can check?
