22 Oct 25 | Server and Stability Statement | Update 18

[h2]Server and Stability Update - Wed 22nd October[/h2][p]Update on our investigations into the server and stability issues since Update 18.[/p][p][/p][p]Thank you to everyone in the community who has been sending us crash reports since our last post. These have been incredibly helpful for the team and are allowing us to narrow down the cause of the crashes.[/p][p][/p][h2]TLDR Summary[/h2]

• [p]The team has identified a likely cause of the crashes related to the PhysX physics engine.[/p]
• [p]These crashes can affect both servers and players, often resulting in multiple players disconnecting at once.[/p]
• [p]During our testing today, we have seen a client crash ourselves when connected to a live server, allowing for more targeted investigation.[/p]
• [p]Some additional crashes may be related to DX12 compatibility issues. Updating drivers or switching to DX11 may help.[/p]
• [p]The team continues to investigate and will provide further updates as progress is made.[/p]
• [p]If you can reproduce the crash, then please reach out to us.[/p]

[p]If any members of the community have been able to reproduce crashes consistently, we would greatly appreciate you sharing the details with us. Knowing how to trigger the issue would significantly speed up our efforts to identify and fix it.[/p][p][/p][h2]Status of the Investigation[/h2][p]From our investigations so far, we have determined that the problem is likely related to a complication within the PhysX physics engine used in Hell Let Loose.[/p][p]There appears to be a crash within the PhysX library that can manifest in several ways. It can cause both servers and connected clients to crash. When this happens, multiple players may crash simultaneously, which explains the instances where groups of players drop out of matches at the same time.[/p][p]This issue has not occurred in our development environment, which makes it more challenging to diagnose. We are working hard to understand what is causing it to occur in the live game, where there are many more variables than in testing.[/p][p]During our testing today, we have seen a client crash ourselves when connected to a live server. Now that we have seen this, we are able to get a number of developers to attempt the same with development tools attached to analyse what in-game scenario triggers the crash within the PhysX library.[/p][p]We hope this breakdown helps provide some clarity on the situation and where we currently stand in our investigation, and as we asked at the start, if anyone has found ways to reproduce this crash consistently do reach out and let us know.[/p][p][/p][h2]Other Crashing Reports - DX12[/h2][p]While reviewing crash reports, we have also seen a number of reports related to DirectX 12 (DX12).[/p][p]In Patch 17.1 the game was changed to use DX12 by default, where it previously used DX11. For players with compatible graphics cards, this provides a performance improvement.[/p][p]However, some graphics card drivers and certain GPUs may experience instability when running DX12, which can lead to crashes.[/p][p]If you are experiencing crashes, please first ensure that you are using the latest graphics card drivers for your system.[/p][p]If crashes continue, you can switch the game to DX11 mode by going to the Game Options menu and changing the “Renderer” setting at the bottom of the Video section to DX11.[/p][p][/p][p][/p][h3]Tue 21 Oct Update:[/h3][h3][dynamiclink][/dynamiclink][/h3]
