Xbox One X: L4D BC "X Enhancement" bugs

Levon68 · Jan 21, 2019

So I was playing split-screen L4D2 recently and ran into a bug when going into underground sections. The "Underground" section of The Passing and the shorter sewer section of The Parish before the graveyard.

When you are actually underground you can see through the ceiling and see black and grey outlines of the buildings above and ceiling is completely gone, just black. Before or after entering the underground sections there will
be weird flat black and grey textures that will block you from seeing the floor. Completely cuts of all visuals of what you should be able to see beneath and in front of you.

This only happens on split-screen and "Graphics" is selected in the X Enhancements menu. When "Performance" is selected the issue is fixed or if you keep "Graphics" selected and change the split-screen config in L4D2 itself to
"Default/Vertical" the bug stop occurring. Changing it to "Horizontal" in split-screen with Graphics enhancements selected causes the issue. Not sure if it effects L4D1, but it should be looked into anyways.

I also notice some odd audio bugs in both 1 & 2, but mostly 2. In split-screen or not like certain sounds coming in and cutting out very quickly like the Witch's intense theme comes in a cuts out very quickly a good bit before
you actually see her, then proceeds to normal as you close in on her. General stuttering and slightly jumpy/cutting out audio all around are also there, but nothing nearly as bad as the visual bug and the random audio cut in/outs.

I don't know if these things are known or not, but they're pretty bad bugs and hopefully someone can help out some how.

I'm not sure where else to report these things to get them noticed by the team of people who work on these things and have been lead here, so thanks for any help.

Thanks for the response. Like I said this issue only occurs on Xbox One X after the 4K update, not with the basic Xbox One or the Xbox 360, so the devs of the actual game (Valve) have nothing to do with it.

These issues did not occur until the specific Xbox One X update happened, so I’m pretty sure that it would be an issue with whoever added this update to the game which, correct me if I am wrong, the team that handles Backwards Compatibility.

And again, these bugs did not start happen until Microsoft/Xbox alone put out this 4K Enhanced update. The original creators/devs of the game had nothing to do with this, I’m pretty sure they haven’t touched the Xbox version of the game since about
2011.

On the original system (Xbox 360) and the basic Xbox One (without the 4K Enhanced update), these bugs do not occur.

Thanks again

You should contact the game's publisher/Developer about any game bugs/issues.

As soon as I am able to, I will get the insider app. Thanks for the tp!

And yes, [Mod Removed - Personal Information] and I would appreciate that very much.

Thanks a ton for the help!

Hello Levon,

We understand that you're experiencing an issue concerning graphical errors/bugs for Left 4 Dead.

The ambassador is correct in stating that the developer would need to be informed of such information, as the game becoming backwards compatible means it is only ported to be played on the Xbox One rather than just on the Xbox 360, and bugs for the game
would have to go through the creators.

Please try reaching out to them, and let us know the results.

Best wishes!
