I occasionally get the folowing error on Tie-Fighter:

"The GPU device instance has been suspended. Use GetDeviceRemovedReason to determine the appropriate action."

I use MSI Afterburner to underlock my card settings. That worked on X-Wing, and seems to have reduced it on Tie Fighter. However, I still do get this error, at which time it crashes to desktop. Very frustrating on a long mission.

Any other suggestions besides underclocking?

Fix what's wrong with your system making it unstable when playing, underclocking shouldn't be required by any game, old or new.

How do I figure out what's wrong with my system, though? I agree underclocking SHOULDN'T be required, but it's commonly listed as a solution for similar problems with playing X-Wing SE on modern systems.

There is a DX11 wrapper for the SE editions and XWA, use that instead, link:

It also allows to scale the 3D graphics resolution to that of your desktop and put some anti aliasing on top, plus it eliminates LODs making the textures a crisper especially on smaller ships.

Thanks. Does this work with Tie Fighter too? I installed the ddraw.dll and the cfg file to my Tie Fighter folder, and the game won't launch. I did replace the ddraw.dll with a different version to initally get the game running a few days ago.

This fork of the same wrapper should work for all 4 games

Sorry for all the questions. When I click on the link it gives me the following files:

impl11
.gitattributes
.gitignore
And several TXT files.

The first three options lead to more files. Which ones do I get to obtain the necessary replacement for Tie Fighter?

After working for several months, suddenly I'm back to the same error. I've installed these fixes, but they no longer seem to work. Any other suggestions?
