So I installed Amnesia The Dark Descent and everything seemed fine until I made it to making a profile and starting screen. It ran very slowly and I couldn't even move the mouse and had to restart the computer. Maybe it's about my graphics card ? I have a nVidia Corporation MCP61 High Definition Audio graphics card.. Thanks ! :)
Okay, you probably mixed something up there. "nVidia Corporation MCP61 High Definition Audio" isn't a graphics card but your sound card. What graphics card you really have is displayed in the "system details" panel. Just type "details" into the dash and it should show up.
If you do have a nvidia or AMD graphics card you probably haven't installed the right graphics driver. Just run the driver installation tool and try installing the proprietary driver for your card. The app should show up when you type "jockey" into the dash.
