Description

Describe the bug

We have tried to run DirectX 9 game with remix-1.2.4 on multiple devices.
For some reason, it works on some of the devices, while on some devices it's impossible to run it (it just crashes on launch).

How do you reproduce the bug?

Crash occurs the same time application is being launched.

I attached 3 crash DMP's in case it can help.

What is the expected behavior?

The application can't launch on Laptop with RTX 4060. I think it should run on almost all RTX devices.

Version

remix-1.2.4

Research direction

Start by reviewing the attached bridge64.log, bridge32.log, remix-dxvk.log, and the three NvRemixBridge.exe crash dumps for the startup failure on the RTX 4060. Compare the reported behavior across the affected devices and determine what evidence identifies the DirectX 9 DLFG-related cause; done means the game launches reliably on the affected configuration.
