Thanks for posting the DXDIAG report.
If you look at the Diagnostics section at the bottom of the report you will see multiple issues that you should look into. While the NVIDIA RTX voice memory leak could be causing your issue, I cannot say for sure.
Some other things to consider...
- If you didn't do a clean install when installing the latest NVIDIA drivers, I suggest you do that.
- Make sure your game launcher(s) is up to date. When I went to confirm SWBF2 works with the drivers you have (it does), the EA app required a restart to work properly.
