Comment 34 for bug 987304

For me several games still run quite slow in Unity, but run okay in Unity 2D or on a seperate X-server.
Recent examples are Dustforce and Oil Rush. For example Oil Rush with ultra/high has 53 fps in the main window on a seperate X-server but only has 33 fps and sluggish mouse cursor under unity. Dustforce is not even a 3D-game and is also slow in Unity, but runs really smoothly in Unity 2D or seperate X-server.
