V-Sync - This locks the vertical sync to your monitor’s refresh rate which may force the game to run at a lower frame rate.Shadow Quality - Detailed shadows can take a whole lot of processing power, so try dropping your shadow quality to get a major performance boost.This is especially important when playing newer video games with older video cards.

Texture Quality - If you're getting intermittent stuttering while playing (as opposed to a low frame rate), you may want to lower your texture quality.If you're getting super-smooth performance and want to try some AA, try FXAA if available first, as this is the cheapest AA solution. Try turning AA off completely and see how your game plays. There are lots of different AA options (MSAA, FSAA, etc.), but for now you just need to know that most of them have a big performance cost. Anti-aliasing (AA) - This is the technique that smooths out the pixelated edges on objects, making edges look more natural.For example, switching from 1920×1080 to 1600×900 will often give you about a 20% boost in FPS. Changing your resolution can give you one of the biggest performance boosts you can get. The game will look blockier, but should instantly feel smoother. Resolution - Games will look best when they're running at your monitor's native resolution, but you can make a big FPS improvement by dropping the resolution down.

Look for some of the following settings in your game's Graphic Options menu for a big impact: X Research source

This may make the game look a little worse, but can lead to massive gains in frames per second (FPS), which will provide a much smoother experience. The best way to get a big performance boost from your games is by lowering the graphical settings.
