Looks like your CPU doesn't support rdtscp instruction and wineboot.exe crashes:

Unhandled exception: illegal instruction in 64-bit code (0x0000000140002b89).

This is only available in experimental and needs to be fixed. Thanks for the report!

@bear-bulloff I've uploaded a build here that should fix this failure: https://www.codeweavers.com/xfer/alasky/proton-test/ with the lock code "cpu". Could you give it a try and see if the games now run on your machine with the CPU in question?

Edited with easier instructions: You can test this build by: 1) Creating a compatibilitytools folder here if it doesn't already exist: ~/.steam/steam/compatibilitytool.d 2) Drop the tarball into compatiblitytool.d 3) Untar 4) Reboot steam 5) Now this version will show up as a Proton version to choose from in the dropdown menu 6) To remove later, just delete the folder in compatibilitytools.d and reboot Steam again

With this version of Proton all the tested games run. Thank you. steam-1774170.log steam-675010.log steam-46510.log

@bear-bulloff Thank you so much for testing :) The fix should be in the next experimental release.

[bear-bulloff]

Thank you. We'll be waiting. Tried to run Battlefield 2042 beta with this version of Proton, a message appears about using an older version of windows 10. steam-1638720.log

Hello @bear-bulloff, that issue is unrelated to the issue reported here. Please use #5200 for feedback on using Battefield 2042 Open Beta with Proton.

[bear-bulloff]

Hello. Okay. I just wanted to add for this particular version of Proton before it was released.

@bear-bulloff The fix for older CPUs was included in the recent proton release - experimental-6.3-20211011b. I'm going to go ahead and close this issue since you already tested the fix; please comment if the problem isn't solved and I can reopen this.
