Torchlight 2: RTX Remix, then game itself, fails to lock vertex buffer

[Expack3]

Describe the bug

• RTX Remix is unable to lock the game's vertex buffer, which leads to the game itself being unable to lock the vertex buffer, resulting in a crash with a log (included under Attach logs! as Ogre.log).
• 0.1.1
• Nvidia GeForce RTX 3060 Laptop
• 531.68
• v.1.25.5.6, Steam

Attach logs!

• NvRemixBridge.log
• d3d9.log
• Torchlight2_d3d9.log
• Ogre.log

To Reproduce Steps to reproduce the behavior:

1. Place the included local_settings.txt in %USERPROFILE%\Documents\My Games\Runic Games\Torchlight 2\
2. Unzip the included rtx.conf and place it in the game's root folder.
3. Run the game through Steam. When prompted, run without mods.
4. Leave the game running at the start menu for, at most, 1 minute. You can start a new game or load an existing one and reach step 5 eventually, but the start menu is the place where the error most quickly and reliably occurs.
5. See error.

Expected behavior Unknown. Best guess is RTX Remix and the game should be able to negotiate access to the vertex buffer.
