Game crashes on second launch: UnityShaderCache problem on AMD cards

anon20000101 · March 3, 2021, 10:15am

Hello

a relevant number of our alpha testers are having a serious but strange issue: they launch the game, play a bit, but when they try to play another time, the game crashes at start and keeps crashing each time they try launching the game.

The crash message looks like this:
Native Crash - Unknown Function (atio6axx)

The Unity player log stops exactly when starting to load the shaders.

We managed to find the cause in the unity shader cache. At the first launch the cache is built (no errors), but a crash happens when Unity tries to load the shader cache on some AMD graphics cards.
Proof: if we make the tester delete the UnityShaderCache in the AppData\Local\Temp… game folder, the game starts without crashing.

We already made them update the graphics card drivers, with no results.

The issue happened with these graphics card:
Radeon RX 580 Series
Radeon RX 470 Graphics
AMD Radeon RX Vega 11 Graphics

We found the problem on Unity 2019.4.7, then we moved to 2020.2.4 to see if the issue was already solved, but same problem.

Now the questions:

Is it a Unity issue, or a graphics card driver issue?
Is there a way to force the deletion of the UnityShaderCache folder before starting up the game?
Is there a way to enable some detailed log so we can understand which shader is causing the issue?

Thanks!

@ please report a bug - there is not enough information to understand, what exactly is happening here.

Not enough information to answer this.
Not built-in.
There’s a checkbox in the graphics settings to enable logging whenever a shader variant is compiled.

Hi aleksandrk, thanks for replying.

Actually, I’ve found a way to add a workaround as point 2, with a class made like this, that seems to be called just before shader loading:

class GameLoadClass
{

#if UNITY_STANDALONE_WIN
    [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSplashScreen)]
    static void OnBeforeLoadRuntimeMethod()
    {
        Debug.Log("Trying to delete UnityShaderCache");
        Debug.Log("Application.temporaryCachePath: " + Application.temporaryCachePath);

        string shaderCacheFolder = Application.temporaryCachePath + "/UnityShaderCache";
        DirectoryInfo di = new DirectoryInfo(shaderCacheFolder);

        int num = 0;
        foreach (FileInfo file in di.GetFiles())
        {
            file.Delete();
            num++;
        }

        Debug.Log(num.ToString() + " Files deleted");
    }
#endif
}

I’ll send a bug report, so you’ll be able to repro the issue, thanks

I’ve opened a bug report with id 1319559

Users are reporting this crash:

atidxx64.dll caused an Access Violation (0xc0000005)
in module atidxx64.dll at 0033:91b173df.

They all have AMD cards:
AMD Radeon™ Vega 8 Graphics
AMD Radeon™ Vega 10 Graphics
AMD Radeon™ Graphics (ID=0x1636)

Unfortunately this fix doesn’t work, because for some reason in my game there is no UnityShaderCache in AppData\Local\Temp.…
The builds are Unity 2020.2.6f1.

EDIT: Updating the AMD drivers have been reported to work.
