Seeking assistance to improve windows 10 performance on Proxmox VE 8.3

[server_steel]

Hello

I am new to the Proxmox world and have installed Proxmox VE 8.3 on the following setup:

• ASUS Prime B250-PRO
• i5-7500
• Kingston - HX424C12SB2/8
• 120GB SSD for Proxmox and another 120GB SSD specifically for the Windows virtual machine

I installed Windows 10 following this video: https://www.youtube.com/watch?v=eyNlGAzf-L4

Everything works properly except for the system's fluidity (Windows 10, in this case - I experience the same issue in other operating systems, such as Ubuntu.). My issues are:

1. When I open a folder, I notice a slight delay in the process, a bit of lag.
2. I work with AutoCAD and notice a slight imprecision with the mouse. I have to move the mouse very slowly to achieve precision.
3. When I close or open the browser (Firefox), I notice that the opening process is slow.
4. When moving the mouse, I notice that the response is sluggish. I've already set the mouse sensitivity to maximum in Windows.

I access the virtual machine through the browser and use the "full screen" functionality to work with Windows 10. I will share all my configurations next. I also have a monitor connected directly to the Proxmox host computer because I read that this might resolve issues related to the system's graphics performance.

What can I do to improve the fluidity and make the most of the system?

Did you try to use `Host` in the VM config?

Do you use noVNC or Spice Remote Desktop?
