Ever struggled with your graphics setting for your PC? Then read this article to find out. Not all the terms are covered but almost every necessary settings have been explained:
Starting with resolution, a very basic term which means the number of pixels contained on display. A higher resolution means you'll see more details. A higher resolution will bring more clarity but this also means your GPU will use more power to render the extra pixels. So your performance may degrade depending on graphics card.
This is also an important setting that most of us don't know about. Without V-Sync, your graphics card is free to render frames at a rate higher than your monitor can actually display them. And this will result in screen tearing. Enabling V-Sync limits your graphics card's ability to render frames per second. For example: if your monitor refresh rate is 60hz then it will run your game constantly at 60 FPS. Some complex scenes can create a problem because your GPU will try to maintain 60 FPS even when it is struggling to maintain FPS. Only use it when experiencing screen tearing.
In some games, you must have noticed zigzag lines and uneven edges on objects. So in that case Anti-Aliasing helps to get rid of those lines. This will help to make the far away objects look much smoother. Basically, the output will be more pleasing and realistic. Even the grasses will look more real and less zigzaggy. It will minimize the distortion but will affect your graphics performance. You have to check it out yourself to see which suits the best for your PC.
Multisampling Anti-aliasing (MSAA): The MSAA sampling process requires fewer resources by supersampling only parts of the image, particularly polygons. This process is not as resource intensive. However, MSAA doesn't perform well with alpha/transparent textures, and because it doesn't sample the entire scene, image quality may be reduced.
Fast Approximate Anti-aliasing (FXAA): FXAA is an improvement on MSAA that is much faster with less hardware performance cost. Plus, it smooths out the edges on the entire image. Images with FXAA antialiasing can, however, appear a bit more blurry, which isn't useful if you're looking for sharp graphics.
Temporal Anti-aliasing (TXAA): TXAA is a newer antialiasing process that produces improved results over FXAA by incorporating several different smoothing techniques, but with a slightly higher performance cost. This method doesn't work on all graphics cards.
Screen Space Ambient Occlusion (SSAO)
This is a method that calculates how brightly a light should be shining on a part of a scene. This will basically simulate shadows but based on light and environment. The performance will not affect much and this method is more of a hit and trial. This works for some game very well but for some game shadows may not favor the situation. This technique was developed by Crytek.
It will soften your graphics and bring a glowing effect. In other words, it will bring bloom and characters and object will look smooth. This affects your performance a lot and should enable only when you have a decent graphics card. It adds motion blur and your graphics look treat to your eyes.
Depth of Field
The Depth of Field settings attempts to blur distant objects. The setting controls the intensity of the blur, not the distance at which objects start to blur. The performance is slightly affected but not to that extent. It will keep your main character in focus and is helpful for people with nearsightedness.
This effect will cancel the blurry textures which are generated at a certain angle. Image quality will improve at 16x but also the FPS will decrease. So everything comes at a cost. Experiencing better graphics will reduce the performance. The impact on the performance is lesser but if you have a potato PC then it is recommended at 1x.
