I have 0 dedicated video memory?

Dear reader,

I have a Dell brand notebook with an Intel Core I5 3320M built in with the Intel HD Graphics 4000 APU and 12 GB Ram (retrofitted). I've been gambling on my laptop for a long time with heavy lags (by that I mean that sometimes it just starts to lag and then stops again). I recently Googled the errors and ran into the problem. It is because the video memory can't withstand a game (e.g. Fortnite 25-35 FPS with lags as explained above). I already noticed that the graphics memory of an APU has something to do with the RAM. I've tried many things to increase this memory, but nothing has changed. In my adapter properties of the APU it says that I have a total of available graphics memory: 1792 MB, and with dedicated as well as system video memory I have 0. Would anyone have an explanation or a possibility how I can increase the graphics memory?

Yes is also completely logical. You don't have a dedicated graphics card with its own video memory, but an APU. So a processor that has an integrated graphics card.

And this graphics card then branches off memory from RAM.

But you can't increase this at will.

It's clear if you have APU graphics solution. If you don't want that to be the case, you'll have to buy a notebook with a dedicated graphics card.

Such a graphics solution uses your main memory, which is also much slower than the memory usually used on graphics cards.

This is not a notebook for gaming, apart from the fact that the hardware is generally pretty old-fashioned. The processor has been on the market since 2012.

The CPU has an integrated graphics unit (iGPU). With Intel, the "problem" is that, in contrast to the ones AMD uses in their APUs, they are only suitable for office stories. What is going on there are e-sports titles like CounterStrike.

An iGPU / APU branches off part of the main memory for itself, in order to get a little more performance, you should always operate memory in the so-called dual channel (i.e. 2x4GB or 2x8GB, for example), because AMD scales the performance very much with it.

As far as everything is correct, however, Intel has also done its homework according to Intel HD, HD 2000/3000/4000 with regard to its integrated graphics solutions and continues to refine it.

But correct from you, because 2012/2013 was a long time ago in relation to the Intel HD 4000 compared to today's APUs and SoC.
