Why does ubuntu lag on VBox?

Question

virtual box

Installed ubuntu on virtual box. My specs: i38100, 8bg ram, gtx1650GAMING X(4GB) graphics card. In virtual box, I allocated 128 MB of video memory, 3 processors, 5 GB of RAM, turned on 3d acceleration, in the paravirtualization section I chose HYPER-V. Everything seems to be ok, but ubuntu slows down, it can be seen even when scrolling, it hurts the eye hard. Also, when I open the application list, the picture appears to be distorted for a second when applications appear. I read that Ubuntu slows down because it does not have video card drivers and that you need to install guest additions. I installed them via : Devices, Connect Guest Additions. I read that this might not help (it didn't help me) and downloaded it via the console. Still doesn't help. What should I do? Help please

Let's start with the simplest question :) - what was the task? There is no video card in VB , there is some kind of imitation of it that appears after installing add-ons, but still looks like an ass. For testing, for debugging, for working with the console, it is suitable. Of course, you won’t watch the video and you won’t drive games :)
