If you want to get a short answer, it is-graphics cards are very important for large games!

Let's just say that the big game you mentioned is located in the big game now. It is conceivable that the "big game" of 10 years ago runs without problems with today's integrated graphics card. What kind of large game graphics card is the most expensive now? First-person shooting (you should have heard of the island crisis), racing games (Need for Speed 18) and so on. At present, 99% of popular games are 3D games. To some extent, the performance of 3D directly affects the running speed of the game. How is the game screen displayed? But through the operation of the graphics card, the core of the graphics card is the brain of the whole graphics card, just like the cpu, which directly determines the running speed of your computer. On the one hand, the core of the graphics card, memory size and memory speed are also very important. Even if you have a super awesome graphics card core but dominate 128MB memory, well, you can play minesweeper smoothly ... at least for now, you need at least 2GB memory to play general large-scale games. I'm not going to go on about the graphics card. If you want to know, you can continue to ask me, or Baidu or Google.

In fact, in addition to the graphics card, I think there are many hardware that will affect the game experience, such as CPU, memory and hard disk. Nowadays, computer bottlenecks usually appear on hard disks. Mechanical hard disk has been developed for so many years, but it has not been improved qualitatively. If you want to play cool games, I recommend you buy a solid-state hard disk, which will make you read pictures much faster!
