If you can, disable shader caching. There are a few tests you can do: 1. Did you try with the kernel parameters I posted above? I always ran all the parameters together. GPU+CPU and at the time, I did not have crashes for weeks on my Vega64. I am using a RadeonVII now and it seems those parameters are not needed. 2. Valve sponsored an interesting project that removes dependency of AMD Mesa from LLVM. And instead uses ACO. Valve made this available for Arch based systems via AUR, and Ubuntu based system via PPA. If you want to test it, you can check the posts below. I am going to test this myself on both Arch and Ubuntu. <a href="https://steamcommunity.com/games/221410/announcements/detail/1602634609636894200">https://steamcommunity.com/games/221410/announcements/detail/1602634609636894200</a> <a href="https://steamcommunity.com/app/221410/discussions/0/1640915206474070669/">https://steamcommunity.com/app/221410/discussions/0/1640915206474070669/</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
