5 important graphical settings when playing games

5 important graphical settings when playing games. When accelerating or increasing the quality of the graphics card, you are sure to encounter features like Antialiasing (AA) or V-sync. So you really understand the use of these features or not? When should you turn on and off features like AA and V-sync?

According to HowToGeek, Windows games often give you a lot of different graphics options. Each option will force you to choose between processing speed and graphics quality, but developers often overlook the use of each feature.

Among the myriad of graphics options, there are five most important options you need to understand:

1. Resolution (Resolution)

Resolution is a simple concept: the number of pixels on the screen when playing games. All LCDs have a “standard” resolution – the maximum resolution of the screen. When using Windows or lightweight applications, you should use “standard” resolution due to the use of different resolutions that will distort the image. Not to mention the screen will still have to enlarge the input signal size to the “standard” resolution.

However, when playing games, things are not so simple. Using the maximum resolution of the screen will definitely give you the highest quality graphics. It will also lose most of your video card power. For example, if you have a 1920 x 1080p display, your graphics card will need to display about 2 million pixels per frame. If you want to play slower, tighter games, you will have to lower the resolution down. For example, at 1366 x 768 resolution, the number of pixels per frame decreases to about 1 million pixels.

By reducing the resolution, your screen will enlarge the received signal size. Of course the graphics of the game will be fuzzy and of poorer quality.

In general, if enough hardware power, you should run the game with maximum resolution. Running games at lower resolutions will reduce the quality, but will increase the processing speed, especially on older hardware.

2. V-Sync (Vertical Sync)

Vertical Sync is also called V-Sync, which translates to: vertical sync. The idea behind V-Sync is to synchronize the number of frames per second on the screen with the refresh rate of the screen.

For example, most LCDs have a refresh rate of 60Hz. This number means that your screen can display 60 frames per second (in fact, the scanning frequency is 60 pixels per second). Even if the graphics card outputs 100 frames per second, your screen will still display only 60 frames per second. As such, your graphics card is wasting power in vain.

V-Sync will do the task of synchronizing the number of frames that the screen output with the refresh rate of the screen. In other words, keep it at 60 frames per second. If there is V-Sync, tearing screen will not occur. This means that the screen will display a portion of the previous frame and a portion of the frame later. Both will make the image as torn apart.

However, V-Sync can cause many problems. When V-Sync is turned on, some games are severely disabled (e.g. down to “acceptable” 30 frames per second) and can also be triggered by the lag phenomenon).

Thus, in the case of normal gaming, not torn, you should not enable V-Sync. Otherwise, if you have a tornado, you can try turning on the V-Sync feature. You need to turn off V-Sync so that you do not experience too much frame distortion and cause lag. This will make sure that you live with the tear status.

After all, the most important factor in gaming is still reflexive as quickly as possible.

3. Texture Filtering

In general, games often paint surfaces on flat / curved surfaces to create details that help them look more real, such as wood on a desk. Thanks to the surface vein filter technology, the vein layers become sharper and less opaque.

While playing games, you can choose the right AF level to own the nice graphics, but still do not sacrifice the speed of the game. 4X AF or 8X AF is the right choice for mid-range gaming PCs.

4. Antialiasing (Anti-aliasing)

Aliasing is an effect that occurs when the lines of the frame are not displayed as continuous lines that are scarred into jagged edges. For example, you can look at the edge of a sword in the game when playing games. And you realize that the blade has jagged edges, broken pixels instead of smooth lines and sharp lines like in real life.

Antialiasing (commonly called AA) is a technique known as anti-aliasing and produces lines that are naturally shaped like real life. Common antialiasing techniques will take frame samples when rendered and before they are exported to the screen, “blending” jagged edges into the surrounding environment to create a more realistic feel.

Antialiasing levels, such as 2X, 4X, 8X, and 16X are the number of times images are sampled by anti-aliasing filter. The more sampling, the sharper the image, but more hardware resources.

If you have a small screen, but high resolution, you probably only need to level AA 2X to create sharp images. If your monitor is large, with a low resolution (for example, a 15.6-inch laptop screen with 1366 x 768 resolution), you may need higher levels of AA to avoid image distortion. Broken into pixels and jagged edges.

Modern games use some of the more advanced antialiasing features, such as FXAA with improved algorithms to improve performance.

5. Ambient Occlusion

Ambient Occlusion (commonly known as AO) is a technique that allows the creation of light effects in games. The engine (source code for the game) usually supports the rendering of light sources (for example, street lights) that allow illumination of 3D objects. The AO function calculates which pixels in the scene will be illuminated from the corresponding light source. And how bright this pixel will be. In essence, AO shadows the frame to make the image more real and natural.

Currently, there are two levels of AO processing: SSAO and HBAO / HDAO. SSAO (screen space ambient occlusion) will reproduce light and shadow not exactly. However, it does not cost too much hardware. HBAO (horizon-based ambient occlusion) and HDAO (high-definition ambient occlusion). In essence, they are the same and provide good image quality. HBAO is reserved for NVDIA graphics cards, while HDAO is for ATI / AMD graphics cards.

Other options in the game

Some other options in the game are pretty straightforward:

– Texture Quality: The resolution of the surface vein. The higher the texture quality, the better the game, but the lower the frame.

– Shadows: Shadows of objects in the game. High quality shadows (High) are more beautiful and realistic, but can also reduce the number of frames significantly.

– Motion Blur: Create motion blur. This effect can adversely affect game speed, but not so much.

– Smoke: Smoke effect. Blurry smoke can significantly reduce the frame rate in the game.

– Grass / Tree Quality: Grass effect / quality display, natural environment. Some games allow you to customize the quality / quantity of game plants. Note that displaying too many plants will cause the game to jerky.

You can customize some graphics settings from the video card driver, instead of customizing the game. In any case, you will have to trade between performance and image quality: the better the picture, the better the game, the opposite to the smooth running game you will have to choose the low option.
