Found an important reason for AD lag [Copy link]

 

I reinstalled AD20 on my old computer today, and then opened the old big board. I found that the zooming in and out of the 2D display was very laggy, and the 3D display was stuck like a PPT. I thought that even if the computer was old, I had already added 16G of memory, so this shouldn't happen. Then I went to the task manager and found that AD was actually calling the integrated graphics card of the CPU! ! ! , AD's official website pointed out that AD's display effect requires Direct X 10 support, so the requirements for the graphics card are relatively high. It is definitely not enough for AD to use an integrated graphics card . According to AD's requirements, the graphics card specifications should be higher than GTX 1060 or RX 470 to work properly. Therefore, if there is a discrete graphics card on the computer, and the discrete graphics card is higher than the minimum requirement but still stuck, you should check whether AD is calling the discrete graphics card normally . If you find that the discrete graphics card is not called, you should adjust the graphics card settings in the corresponding graphics card management software and set it to high-performance mode, or directly specify AD to call the discrete graphics card in the software. After restarting and opening AD again, the operation will become very smooth, and you will find that the working graphics card is GPU1 when you look at the GPU in the task manager.

It should still be configured in the computer. Generally, if there is a dedicated graphics card, the dedicated graphics card will be directly called.

AD shouldn't lag. Try other files. Is there too many constraints on your file?

This is a 16-layer board of AD's mini PC. Then I found that it was using the CPU's integrated graphics card, which was not good enough. A graphics card with performance higher than 700 GFLOPS was needed to run smoothly. The larger the board, the higher the requirement. Then I changed the graphics card to a discrete graphics card.

The laptop sometimes messes up and uses the integrated graphics card by default, which causes a lot of lag.

The new version is stuck, which may be related to the network activity option under the system in the settings

This means that the new version has a strong desire to connect to the server when the software is started. This should be caused by something else, and you need to turn off functions such as connecting to the network when the computer is started.

Specific settings that need to be configured

Those are the same. They always want to connect to the server. When they start up, they always open the supply chain stuff and can't be turned off. They can only be set not to connect to the server.

I always thought it was a problem with the memory stick, or insufficient graphics card performance, or a driver problem.

The graphics card has the most obvious impact. If you use the integrated graphics card, the motherboard will be stuck.

Integrated graphics cards have supported DX10 many years ago, and even supported DX11 for some time. Today's CPU integrated graphics cards already support DX12, and the performance is no longer just that of a nobody, especially AMD's products. The CPU integrated core graphics card is already the GPU used by current mid-range discrete graphics cards, which is more than capable of handling large-scale 3D games and complex graphics.

The performance of early integrated graphics cards, especially those integrated in early Intel mobile CPUs, was very poor, which was unavoidable, so many early laptops were equipped with independent graphics cards. Newer integrated graphics cards (referring to those from a few years ago) have no performance problems, but they require correct driver installation and reasonable configuration to achieve sufficient performance, while current integrated graphics cards (referring to those within the past three years) have much lower requirements for human intervention in configuration.

Large boards involve a large amount of data, so sufficient virtual video memory must be configured (simulated using system memory), otherwise even if the GPU performance is good, it will be very slow.

AD officially said that the minimum performance of the graphics card must be more than 700GFLOPS. The parameters of the RM240 graphics card in my old computer are only more than 600. I bought it for more than 3,000 yuan in 2015. It was also a rubbish configuration at the time, and it is even rubbish now.

My laptop does not lag when using AD, but the board has very few layers, and it has a core graphics card + a discrete graphics card. The memory is 8G and cannot be expanded to 16G. It is limited by the motherboard.

AD official website says that this is limited by the number of devices and networks. If there are more than 1,000 devices and 1,000 networks, a high-end computer will be required.

Back then, most laptops were powered by Intel processors, but Intel's integrated graphics were terrible, especially on mobile devices. Now Intel's integrated graphics have improved a lot, but they are still far from the level of GTX1060 discrete graphics.

AMD's integrated graphics are much better than Intel's, and generally have double or more performance at the same price. In the past few years, the integrated graphics of Ryzen APUs are equivalent to GTX1050 discrete graphics, and now the latest high-end APU models are only faster. However, AMD now has two product lines, CPU and APU. The CPU series does not have an integrated GPU or only has a "boot card", which is obviously intended to compete with Intel's Xeon.

The most powerful integrated graphics card is Apple's M series processor. The integrated graphics card of the first-generation M1 basic version is stronger than the GTX1050 discrete graphics card, and the M2 basic version is basically equivalent to the GTX1060. The integrated graphics card of the M1 Ultra version can actually surpass the GTX1080 by a large margin, reaching the performance of the high-end RTX3060Ti/RX6750XT discrete graphics card. Of course, the M2 Ultra will be even more powerful, and it is said that the M3 will be released this year.

The computing power of the GPU integrated into the CPU is not necessarily weak, even if it is Intel's. Ten years ago (2013), the fourth-generation Core Haswell released by Intel had an integrated graphics card with a theoretical floating-point computing value of up to 640GFlops, but due to the lack of high-bandwidth video memory, it could only use system RAM for simulation, which greatly reduced the actual computing power, by half or more. Many years ago, AMD's APU directly integrated the GPU of a mid-range discrete graphics card. Although its performance is much stronger than Intel's, it is still far inferior to its own discrete graphics cards of the same level. Apple is really an "outlier". Not only did it rebel against the x86 system, but its integrated graphics card also directly targets high-end discrete graphics cards. It is just not open and is too expensive...

I just checked and found that the theoretical computing speed of the integrated graphics card of the obsolete 4G mobile phone processor Snapdragon 855 can reach 730GFlops. Of course, it will be limited by the lack of video memory and the actual performance will be greatly reduced.

For integrated graphics cards, since there is no dedicated video memory, the memory module has a great impact on the GPU. For example, the "dual-channel memory module" and the memory BIOS parameter settings have little effect on the general performance of the computer, or even difficult to detect, but the impact on the GPU speed measurement is obvious. If the operating system is not properly configured/maintained, the overall machine operation efficiency is more likely to drop.

The driver has a significant impact on discrete graphics cards, but not on integrated graphics cards. After all, integrated graphics cards are unified, unlike discrete graphics cards, which have their own unique features. Even for the same GPU model, some graphics card manufacturers focus on performance, while others focus on cheapness.
