best dpi for fps

5. Resolution and Landscape I spent a huge amount of time dealing with DPI and resolution problems. I don't believe it. The total development time from 1/3 to 1/4 is processing DPI and resolution problems, this is really puzzling, because today's Android and iOS development almost do not need to consider these issues, Windows Phone 7 and Windows 8 do not need to be used, how can I so toss? 5.1. Spend some

How to slim down your Android Installation File (APK) It is an indisputable fact that the apk file of Android is getting bigger and bigger. In Android or the original version, the apk file size of an app is only about 2 MB. Now, the size of the apk file of an app has been upgraded to 10 MB to 20 MB. The explosive growth in the size of apk files is mainly because users' expectations for app quality are getting higher and higher, as well as developers' development experience is increasing. These

, designers and developers must create user interfaces that work well with the small s Pace of a phone, and the large space of a tablet. They also must take to account have image resources optimized for high and low density screens. While there is many ways to create optimized user interfaces for different screen sizes and orientations, the focus of th Is blogging is what Android supports different screen densities. The basic design concept of Android is to has the user interfaces that has eleme

VSync is the abbreviation of the vertical period (Vertical synchronization). The main idea is to set your FPS and display refresh rate up to the same time. The aim is to avoid a phenomenon called "tearing". I will describe these details again below.Each CRT display has its own refresh rate. The unit is Hz. The value is the number of times the monitor updates the screen per second. Different displays support different refresh rates at different resolut

Mouse refresh rate is also called the mouse sampling frequency, refers to the mouse can collect and process the number of images per second. Refresh rate is also one of the important performance indicators of the mouse, that is, the mouse every second can be collected image data, generally "fps/s (frame/sec)" as a unit. 　　The significance of the concept of mouse refresh rate Mouse refresh rate So to speak, even if the optical mouse has many advantag

make this gradient smoother is to use softer motion effects-for example, to dilute the object's color or to reduce its brightness, and only one frame of transparency is set when the gradient is complete. For smooth animations, objects may still be overly complex on the graph. Therefore, you may only be able to use a flat color block to complete the actual gradient. What you create here is called obfuscation in the cartoon terminology (see Figure 1). You create the eye's perception of motion, no

I. Several Concepts about resolution To accurately grasp and understand the meaning of resolution, it is necessary to clarify the following concepts.Resolution: Includes device resolution, screen resolution, graphic resolution, scan resolution, and bit resolution.Device resolution: the number of points that can be generated on each inch of an output device, such as display, inkjet printer, laser printer, hot wax printer, and plotter. This resolution is measured by the unit of

four times the original size.Scan resolutionScan resolution: the resolution set before scanning an image. It affects the quality and performance of the generated image file. It determines the way in which the image will be displayed or printed. If the scanned image is used for Screen Display of 640x480 pixels, the scanning resolution does not need to be greater than the device resolution of the general display screen, that is, the scanning resolution generally does not exceed 120

Dip: Device Independent pixels (device independent pixel ). Different devices have different display effects, which are related to the hardware of the device. We recommend that you use this function to support WVGA, hvga, and qvga without pixels.Density-independent pixels, an abstract unit based on the physical density of the screen. Density can be understood as the number of pixels per inch (unit: DPI). 1dp is actually equivalent to a point on the sc

. Let's adjust the computer settings: Right-click on the desktop> Properties> Settings> advanced> General> DPI setting> 96 DPI. Try to change the settings, set it to 72 dpi, restart, and then open the browser to see that 72px is equivalent to 72pt. Why? Let's try another experiment: Let's use 800x600 and 1024x768 to see the example above. Obviously, the text gets
