[Render] Quitting Freelancer on dx9 (dxwrapper) doesn't actually kill the process

Type: Render
Bug: Quitting Freelancer on dx9 (dxwrapper) doesn't actually kill the process

Reproduction Steps:

• On DSLauncher: click "Render Mode" and select DirectX 9 (dxwrapper); Use Desktop Resolution ON; Windowed Mode OFF (i.e. exclusive fullscreen on)
  
• Launch Game, wait for it to load
  
• Quit the game
  
• Notice how the Freelancer.exe process still exists in the task manager (under the details tab).
  

Expected behaviour: Kill the Freelancer.exe process. This doesn't happen on DirectX 8 (native).

Pushed a renderer related update just now that might have resolved this issue, please retest and report back.

Hello. I've updated the launcher and tried again. It seems like it's still happening:


The launcher recognises the process and prompts to kill it when clicking "Launch Game":


Clicking "yes" indeed kills the process and starts a new one. Exiting the game doesn't kill the new process:

Will check again asap.

Still happening.




Are there any logs or other kinds of outputs that I could provide to help debug this issue?

This occurrs because Freelancer would wait for an indefinitely running thread to finish. The following patch of DAlib.dll by BC46 would prevents Freelancer from running in the background after exiting the game in some cases: offset 0x004BF4, change FF to 00.

Don't we already have that change as of Discovery 5.1, @Groshyr?

Quite sure I didn't bring it. Better double check it. I won't have access to my PC for another hour tho

I am quite sure:

FF -> 00 dalib.dll 004BF4 BC46 Prevents Freelancer from running in the background after exiting the game in some cases. This occurred because Freelancer would wait for an indefinitely running thread to finish.

We are still missing reliable reproduction steps here.

For what it's worth, I also have the same value on that address:

$ md5sum dalib.dll
fcab0566fc7ea38c787d105f676af102 dalib.dll

I'm on Linux atm but I did reproduce the issue on Windows 11.
A note, I do use RTSS to bump the framerate to the highest legal value, and I've got NVIDIA's overlay running too. Could that change anything?
