How can I tell if the graphics card is not working or the CPU is not working?

The method I often use to determine the performance bottleneck of the CPU and graphics card is to adjust the game resolution, because the various special effects in PC games have a large impact on the CPU, some have a large impact on the graphics card, and some have an impact on both, so It is difficult to judge, but the resolution option is available in every game, and the resolution has little effect on the performance of the CPU. 95% of the impact is on the graphics card side, so we can judge the performance by adjusting the resolution. bottleneck.

 

As we all know, the higher the resolution, the more pixels the graphics card needs to render, and the lower the number of frames. The performance pressure at 2K and 4K resolutions is generally on the graphics card side. The stronger the graphics card, the higher the number of frames, but The low resolution of about 720P is often a test of the performance of the CPU. For example, you can adjust the game resolution to 720P or even lower. If you find that the number of frames does not change much from the previous one, it may indicate that the CPU is not good enough and a bottleneck , If you see a substantial increase in the number of frames, it means that the performance bottleneck of your computer is still on the graphics card, or at least the CPU has not dragged the graphics card.

 

At present, most games still require more graphics cards than CPUs. As long as the graphics cards are strong enough to play, there is no problem, but there are also some large-scale 3A games that require high CPU requirements, such as games such as "GTA5" and "Assassin's Creed". Due to the large number of NPCs and scenes, the calculation pressure on the CPU is very high. At this time, you can use a test tool such as GamePlus to check the CPU and graphics card occupancy. If the graphics card occupies more than 90%, it is normal. If the graphics card occupancy rate It is often at 50% or 60%. This may be because the CPU has a bottleneck. You need to upgrade a stronger CPU to achieve a higher frame rate.

 

In short, a balance should be paid to the computer hardware collocation, especially for playing games. The price of the graphics card is generally higher than that of the CPU. However, if the price of the graphics card reaches more than 2,000 yuan, and the CPU is only a few hundred yuan, the i3 8100 is not suitable. For the requirements of graphics creation, the CPU should be better, especially the more cores, the better, and the thousand-yuan gtx1050 graphics card is basically enough.
