Computer 2K144hz why dual-camera plus capture card live
There are many computer games at present, such as common Jedi Survival, Overwatch, CSGO and other game anchors. More and more game consoles will choose higher 2k resolution 144hz high refresh rate gaming monitors. This type of display not only The resolution alone is a big improvement over the previous 1080p. The key is that a high refresh rate brings a better gaming experience. And when the anchor broadcasts the game live, it needs to use two computers plus a capture card to perform the live broadcast. Why? Because dual-camera live broadcast can save the system resources of the game computer to the greatest extent without slowing down the game computer.
If you open the live broadcast software such as OBS / Live Assistant on the gaming computer, you will find that the CPU of the computer will be occupied by the live broadcast software a lot, and there will be a frame drop in the game, and the computer will change the card. Originally, the game can reach 60 frames After dropping the live broadcast software, the frame is dropped, just like watching PPT, which makes the 144HZ display not show its true performance.
At this time you have several options:
Reduce the live broadcast specifications, sacrificing the live broadcast effect. Resolution 1080p and 720p can roughly double the pressure, 60hz, 48 and 30 (FPS games are recommended not to be as low as 30, let alone less than 30) and other adjustable options such as the zoom filter in OBS and CPU presets Assume.
When upgrading the hardware, it should be noted that obs will use the graphics card to help, and there is a certain graphics card occupation. So do your own calculations. What is the percentage of live broadcast, then if you want to achieve the previous experience, you must upgrade the CPU and graphics performance by 100%. Everyone knows that the hardware price is getting steeper as the performance improves. of. However, it cannot completely solve the problem of a live broadcast freeze on a computer, which even leads to a serious decline in game experience.
Therefore, the anchor will broadcast live with dual cameras and capture cards, so playing the game will not affect the experience at all. In the final analysis, most people, especially gamers, our cpu and graphics cards are hard-working laborers. Species. Just pick up some trash with a power supply case, old monitor, broken mouse and keyboard, don't really need any money, plus a capture card, it is estimated that it will not reach your money to upgrade a set of u.
When you belong to the following situations, I suggest you use this solution:
There are graphics cards cpu that have been upgraded
You already have two computers, or a computer with a boyfriend and girlfriend next to you.
Dual-machine (capture card) solution
Looks like this
The principle is also very simple. The gaming computer is only responsible for playing games. All connections of the gaming computer itself are completely unchanged. It only connects from the computer's graphics card to an HDMI interface to the capture card, so he uses the capture card as a display, and the capture card captures this piece. "Monitor" video data, and because it is installed on the live broadcast computer, this data can be captured by the live broadcast computer (OBS) (the live broadcast computer uses the capture card as a video input source, just like the live broadcast computer has a camera connected to it). In this way, the gaming computer uses another computer to broadcast live, and it does not need to bear any performance pressure related to live streaming, and the game experience will not be affected at all.
The capture card can be PCIe plugged into the main board of the live broadcast host, or USB 3.0 can be connected to the USB interface of the live broadcast computer, and a USB 3.0 capture card notebook can also be used.
Games At present, most game playing computers are 2K144hz, 2K is 2560 * 1440P resolution, so the capture card must support this resolution to not affect the game computer. For example, if your capture card only supports 1080P60, etc., then the game computer is connected to the capture card. It will automatically change to 1080P60 afterwards, which completely affects the gaming experience, and live broadcast has no meaning. At present, there are only a handful of ones on the market that can reach 2K144hz. Let us introduce the Jiu U6 capture card.
The idle HDMI on the graphics card of the gaming computer is connected to the capture card HDMI IN, and the USB 3.0 of the capture card is connected to the live computer host USB 3.0. After the hardware connection is completed, you can set up and broadcast live.
Gaming computer copy
The game computer chooses to copy in the multi-monitor option, that is, copy the display (real) to the display (capture card). Because both the display and the capture card support 2K144hz (2560 * 1440), the game is completely unaffected.
Gaming computers have game sounds and microphone sounds. They are normal on gaming computers. The graphics card HDMI can transmit audio at the same time, so you need to install a virtual sound card on the gaming computer to enable the gaming computer and HDMI to output audio at the same time.
After the gaming computer is set up, the live broadcast computer can open OBS for live broadcast. NineView U6 capture card game computer 2K144hz input. After entering the live broadcast computer, the software calls out 1080P60hz. When not live, the gaming computer is completely unaffected. This operation is currently the simplest and most efficient way to broadcast live computer games.
