Nvidia Tesla P40 for Gaming

Using a Tesla P40 for Gaming with an Intel iGPU as Display Output on Windows 11 22H2. 中文版本

Requirements

1. You will need an Intel iGPU (im using an Intel 13th gen CPU), and
2. A mobo with display output and "Above 4G decoding" option provided.

Steps

1. Enable "Above 4G decoding" in BIOS.
2. Download the latest (528.24 at this moment) Studio driver for Titan Xp or other Pascal Geforce GPUs from Nvidia's official website. It's recommended to perform a clean install. Reboot if required.
3. Run "regedit" and navigate to "HKEY_LOCAL_MACHINE\SYSTEM\". Then press "Ctrl + F" and find "Tesla P40". The path (in the text bar on the top) should be something like "Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000". Only the last 4 digits may vary. Copy the those 4 digits.
4. Create a file at "%APPDATA%\Tesla Workaround\logon.ps1" with the content here. You may want to modify the first several lines. Replace "0000" with the 4 digits you copied in the previous step.
5. Run "taskschd.msc". Right-click "Task Scheduler Library" on the left and create a new task (not a basic task).
6. Name the task whatever you like. Check "Run with highest privileges".
7. On the tab "Triggers", create a new trigger by clicking "New..." on the bottom. Use the "Begin the task" drop-down menu and select the "At log on" option. Click "OK".
8. On the tab "Actions", create a new trigger by clicking "New..." on the bottom. Fill "Program/script" with "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" (with or without quotation marks), and fill "Add arguments (optional)" with '-File "%APPDATA%\Tesla Workaround\logon.ps1"' (without apostrophes).
9. Click "OK", close Task Scheduler, and reboot or manually start the task.
