Cemu

Hi,

Forgive the length of this report, but I feel like the anecdotal background helps to put some context around this issue.

I've got about 40 hours playing XCX on Cemu thus far and I've been experiencing periodic crashes. When the crashes do start, they've seemed to come in a wave. I'll go from rock-solid stable to crash-prone, and then somehow get past the issue without any clear indication of the initial cause or what I did to "fix" it. They start, they persist, and then they go away.

Remediation steps I've tried which have no impact on the problem:

• Deleting the shaderCache folder
• Rebooting
• Updating graphics driver

I'm normally pretty good at identifying patterns in problems like this one, but this one has had me stumped. However, I may finally be on to something. Last night I spent about three hours playing with no problems whatsoever, and then logged off near Eleanora in NLA. This morning upon loading the save, I started crashing within 60 seconds. Nothing I tried could budge the problem - crash, crash, crash on every attempt. Then I recalled when this happened previously (at the base camp in Primordia near the ch.3 Prone camp), I finally ended up loading my save and running away from that "crash area" as fast as I could. I managed to get away without crashing, and then presumed I'd discovered some sort of issue with Cemu rendering that area. But the next time I came back to that area, all was well.

So I tried the same approach with the new problem manifestation in NLA. I loaded my save and ran away from Armory Alley, took the transport to the Industrial District, and then ran out of the west gate. No crash. I ran along the path just past the first stream, and all was still well. Curious to see what would happen, I then doubled back to NLA, took the transport back to the Administrative District, and then ran through Armory Alley. No crash, stable as could be.

Huh. I went about the business of playing again for 30 mins or so, and then had a thought. I had a backup of the previous night's logoff save sitting in the cloud. What would happen if I restored that save and loaded the game? So I tried, and... 100% repeatable crash in Armory Alley once more.

So anyway, my current theory is that Cemu is somehow persisting something in the save game that causes crashing shortly after load. But whatever that bad piece of data is, it must be something transient, because I've now experienced multiple instances where moving far enough away from the problem area will cause the crash behavior to clear.

I've attached an archive including the problem save. Load it, hang a left toward Armory Alley, and then proceed to run down Armory Alley. On my Cemu instance (2.0-86), I am 100% guaranteed to crash before reaching the far end of the alley (or at least I managed 10 or so crashes in a row before I stopped trying).
