The game itself seems to work fine. But when loading into a game it takes me about 30 minutes on my machine (The loading screen seems unresponsive for most of the time, animation plays like once every 5 minutes or so). When loaded into a game I get like <10 FPS (DXVK & WineD3D) and you can visible see the assets and texures being loaded when scrolling through the map (DXVK, with WineD3D it is the same, but there are a lot of graphical glitches in addition). The terminal output attached is with WineD3D. If you require more information please let me know and I will try to provide it. my pc Archlinux Ryzen 2700x 32gb ram AMD Vega 56 (Mesa 20.1.1) game and os on ssd Kind Regards. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 53666] New: Logitech X-56 Stick crashes the joystick subsystem if connected

https://bugs.winehq.org/show_bug.cgi?id=53666 Bug ID: 53666 Summary: Logitech X-56 Stick crashes the joystick subsystem if connected Product: Wine Version: 7.17 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: hid Assignee: wine-bugs(a)winehq.org Reporter: ace(a)haxalot.com Distribution: --- Created attachment 73072 --> https://bugs.winehq.org/attachment.cgi?id=73072 lsusb for X-56 stick With Wine 7.13 and upwards (verified as broken on 7.13, 7.14, 7.15, 7.16, and 7.17) connecting my X-56 Joystick to the system seems to cause an exception in the hid subsystem, with the result of joystick input being completely broken. Attached are debug logs from Wine 7.17 running the built-in control panel, as well as lsusb output for the joystick in question. The throttle seems to work fine, as does gamepads from several brands (original Xbox, Xbox 360, Steam Controller, Atari VCS modern), as well as a Logitech G29 wheel. I also have a Saitech Cyborg X (F.L.Y. 5) which shows the same issue if it is connected when launching (up to Wine 7.16), but works fine if it has been connected after the control panel has already launched. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 52936] New: winhttp:url assumes 0xfb00 cannot be converted to the ANSI codepage, fails with UTF-8 codepage

https://bugs.winehq.org/show_bug.cgi?id=52936 Bug ID: 52936 Summary: winhttp:url assumes 0xfb00 cannot be converted to the ANSI codepage, fails with UTF-8 codepage Product: Wine Version: unspecified Hardware: x86-64 OS: Windows Status: NEW Severity: normal Priority: P2 Component: winhttp Assignee: wine-bugs(a)winehq.org Reporter: fgouget(a)codeweavers.com winhttp:url assumes 0xfb00 cannot be converted to the ANSI codepage and thus fails fails on Windows with the UTF-8 codepage: url.c:306: Test failed: expected failure url.c:307: Test failed: got 0 url.c:346: Test failed: expected failure url.c:347: Test failed: got 0 https://test.winehq.org/data/patterns.html#winhttp:url These two pairs of failures happen when calling WinHttpCreateUrl() on the following URLs respectively: 39 static WCHAR escape3[] = {'?','t','e','x','t','=',0xfb00,0}; 40 static WCHAR escape4[] = {'/','t','e','x','t','=',0xfb00,0}; So maybe these tests should be skipped when running in a UTF-8 locale since it's supposed to be able to handle any UTF-16 codepoint. What is surprising is that this test does not fail on debian11-hi-IN (where GetACP()==UTF-8). That looks like a bug too.

It's certainly doable this way ... but lets hear how Alexandre thinks of this. An alternative to "fix" the holes is by using the static linker. The default 'ld' setting for alignment of LOAD segments without using a custom linker script can be adjusted by using '-z max-page-size=N' and/or '-z common-page-size=N' (target page size).
