1, global shadow effect:

Personal advice is enough to start from the middle, but if it starts low, it will ignore a very important strategic information, that is, shadow, which can show the enemy's position, so it is still very important. Shadow effects mainly affect the shadows of buildings and other objects, and how far you can see from the shadows.

2, model drawing details:

It has a certain impact on the processing of FPS, but personally, if the configuration is not very tight, it is acceptable to open a box, which can make some small details, such as the corner of the box, trees, etc., less blurred, and you can better see if there are people at that far point.

3. Resolution:

The resolution depends entirely on your personal preference, but these are what you need to know: a screen aspect ratio of 4:3 will reduce your fov to 73 degrees, while 16:9 and 16: 10 are 90 degrees; Narrower aspect ratio can bring higher frames per second (fps);

Changing the aspect ratio/resolution will affect your mouse sensitivity (the lower the resolution, the higher the sensitivity). If you don't know which resolution is best for you, use the native resolution of the monitor unless your fps is not enough.

4, multi-sampling antialiasing:

Personally, I think this is an option that needs to be turned off very much, which will cause a lot of occupation of FPS.

5. Map filtering mode:

This still varies from person to person. Generally speaking, after entering the game, the settings can be perfect and normal. If you change it too low or too high, it may lead to blurred vision or decreased FPS.

6, the effect details:

This setting will affect the edge of smoke, smoke from incendiary bombs and smoke from Grenade explosions. Higher effect = more smoke effect. Suggestion: lower it so that you can see the smoke better.

7, light and shadow details:

This setting will produce some weather effects of the map, such as snow and rain. High light and shadow = weather, water opaque, blurred vision, low light and shadow = no weather, water transparent, blurred vision.

Suggestion: low, so there will be no weather effect to interfere with the line of sight, and the screen will not be so blurred. This setting can prevent the line of sight from being disturbed.

8. Wait for vertical synchronization:

This setting will pre-render the picture and delay your picture.

9, dynamic fuzzy:

This setting will blur your screen when you shake the mouse to move the viewing angle.
