Stutters since Update

Sorry to hear this @DeLaurec

Perhaps some of the solutions in this article may be of help:

Please let me know if you and your friend have any improvement.

@DeLaurec, thanks for the clear explanation. Hm, I partly wonder if this is a temporary shader cache issue (similar happens with Darktide), which should usually go away after a few games. That said, as the issue seems to be returning when you restart the game or your PC that’s unusual.

Does the issue persist if you try switching Direct X versions?

Otherwise, it could be worth trying a clean reinstallation of Vermintide 2 (though please note custom settings, keybindings etc. would be deleted and need to be redone)

Hi @DeLaurec,

No problem! Glad to hear that DX 11 isn’t stuttering

It’s a shot in the dark, but you could try deleting your shader_cache.pip_lib file.

1. Press Windows + R
2. Enter %appdata% and select ‘OK’
3. Navigate to: \AppData\Roaming\Fatshark\Vermintide 2
4. Delete your shader_cache.pip_lib file
5. Launch Vermintide 2 as normal with DX 12 (this will create a new .pip_lib file)

Please let me know how this goes.

Ah I see did you try a clean reinstallation of Vermintide 2 before?

Otherwise, I’m admittedly a little stumped as you seem to have exhausted our usual solutions. If that’s the case I would recommend switching and using DX 11.

@DeLaurec if you back up your user_settings.config file and then replace it again afterwards this should keep your settings. I’m not 100% certain about mods.

I’d also recommend booting the game up and checking to see if the stutter persists with a clean config before re-adding your old one though.

You can find your user_settings.config file here:
\AppData\Roaming\Fatshark\Vermintide 2

Thanks for the update. I’ve queried this with our engine developers and they also theorised that your library file may have become corrupted and isn’t saving correctly. Just to be sure, could you try deleting your shader_cache.pipe_lib file once more?

After deleting it, please launch Vermintide 2 and if the stutters occur again, please wait for these to stop, then exit the game, and check again on subsequent game launches to see if the issue persists.

The engine developer provided this explanation:

It’s also good to know that when deleting the shader_cache.pipe_lib it will stutter the first time played, as there is nothing cached. And it will stutter each time a new shader is encountered in game, so it may take a little while until everything is seen and cached.
So if the test was to just delete the file and start the game and experienced stutter, then that is to be expected. However, if the saving of the cache works as expected when shutting down the game, they shouldn’t experience the stutters next time they plays, unless they encounters new shaders that’s not already cached.

Otherwise, our engine developers have said that library file is only saved on shutdown, so they’d like to check if there’s any hidden shutdown crash occurring that might be preventing it from saving. Could you please do the following -

1. Launch Vermintide 2 as usual
2. Once loaded into the Keep, wait for the stuttering/lag to occur and stop
3. Exit Vermintide 2
4. Provide us with your console log from this session

Thanks!

@DeLaurec thanks!

Hm, there are some references to Hardware-Accelerated GPU Scheduling not being enabled. You can enable this by the following:

1. Open the Start menu
2. Search for ‘Graphics Settings’
3. Select ‘Change default graphics settings’
4. Set ‘Hardware-accelerated GPU Scheduling’ to On

It may also be worth a clean reinstallation of your GPU drivers:

Lastly, I also noticed your log contains an error/crash caused by the Crosshair Kill Confirmation mod - so it could be worth disabling this mod.

Please let me know if there’s any improvement!
