This version seems to resolve Battle.Net install and games update, but:
- can not access Warcraft III reforged, I stay at the lion doors which never open

I feel like WC3 Reforged has been broken for over a year at this point. I remember last year trying to play it again since I really like Castle Fight custom map, and I too couldn't get past the lion doors. And prior to that I remember the game randomly freezing. Really sucks because for a few years there, WC3 Reforged just worked.

I wonder what the [redacted] EGS game is... oh, that's the literal name of the game

Is there a commit and a link to the bug for this "Bnet update problem"?
Is it the "writecopy" hack in proton to handle some problem with chromium embedded framework or was it something else?

I've had a battle.net install/update problem just yesterday. Fixed it by switching from flatpak to native packages, and also installing wine + as many optional wine dependencies as possible except the ones that clearly make no sense like printing libraries.
Oh man... good work, but BNet doesn't deserve Eggy.

You may not think it deserves it but many people use it and that's more than enough to get Eggy support.

Thanks for posting stuff like this, as I just ran into a Battle.net update problem today, and I remembered seeing this article. The GE Proton 9-23 version fixed it! (I was previously using the Lutris default.)

I'll come back to linux with kernel 6.14 (ntsync) and NV drivers v570. Lets hope that isn't too long.

I've been playing a fair bit of stalker-2 and noticed I was getting as much as 40fps less under Linux and it was quite noticeable. Probably compounded by Frame-Gen, still, ntsync and the new drivers should help a fair bit, I hope.

Dunno what Nvidia has planned for v570, but I wouldn't expect any major performance improvements? As for ntsync, that is more for robustness / correctness, it's not expected to be much faster than what Proton already does. It will improve vanilla WINE, which is what the touted benchmarks show...

Strange. I get better perf on Linux in STALKER 2, specially on CPU bottlenecked bigger camps. Other places seem about same in terms of performance.
Played 100 hours, finished the game with zero issues.
