Minecraft Super Secret Settings

Automatic graphic performance detection implemented by games are often innacurate and in the case of Bethesda games (like Skyrim) "almost always" would often be more appropriate. I don't have any experience with Saints Row 3, however it may suffer from similar problems.

In the case of your GeForce 550M I must say that it cannot be considered a mid/high-end card but it is instead part of the low-end card segment.

You can forget about playing Metro 2033 at Maximum settings. Can you run it? is generally not a bad service but their results are not always 100% accurate.

At 1366x768 these should be more accurate FPS values for your graphics card when running Metro 2033.

• low: ~ 77 fps
• medium: ~ 42 fps
• high: ~ 15 fps

TR;DL There is nothing wrong in your settings, your GeForce 550M cannot do more than this. Try to lower resolution or graphic settings to increase performance.

Save, quit, and restart. The screen will be back to normal.
