I am experiencing performance and user experience issues with a bare-metal installation of Windows Server 2025 24H2 running on the following hardware:

• Server: Supermicro SYS-521C-NR
• Processor: Intel Xeon Platinum 8558U
• Memory: 128 GB RAM
• Storage: 2 × Intel 960 GB SSDs configured as an Intel Virtual RAID 1
• GPU: NVIDIA RTX PRO 4000

Users connect exclusively through Remote Desktop Services (RDSH). Compared to Windows Server 2019, they report that everything feels noticeably slower. For example:

• Opening context menus is slower.
• Opening folders takes longer.
• Sometimes there is a noticeable delay between typing and the text appearing on screen.
• Adobe applications perform significantly worse.

User profiles are managed with FSLogix.

When I check Device Manager under Display adapters, I see three devices:

1. Microsoft Basic Display Adapter with a 2006 driver (based on the hardware ID, this corresponds to the ASPEED BMC graphics adapter).
2. Microsoft Remote Display Adapter, which I assume is used for Remote Desktop display redirection.
3. NVIDIA RTX PRO 4000.

In Task Manager, the RTX PRO 4000 appears as the GPU, but its utilization is always around 0–1%.

I also performed Google's WebGL/rendering test, and it reports that rendering is being performed by the Microsoft Basic Display Adapter instead of the NVIDIA RTX.

Is it possible that Remote Desktop sessions are using the ASPEED BMC graphics adapter instead of the RTX PRO 4000?

If so, how can I configure Windows Server 2025 so that Remote Desktop sessions use the NVIDIA GPU and provide performance comparable to what we see on Windows Server 2019?

Has anyone experienced similar performance issues with Windows Server 2025 24H2 in an RDSH environment?
