Bug ID: 55903 Summary: Falcon BMS 4.37u3: game randomly fails to load 3D models Product: Wine Version: 8.17 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: xeno@x-s.com.pl Distribution: ---
Created attachment 75439 --> https://bugs.winehq.org/attachment.cgi?id=75439 Screenshots of the problem
On random runs no 3D models are visible in game, both in TacRef (game encyclopedia) and in 3D world (screenshots attached). If it happens there are messages in the game debug logs about skipping load LODs:
Log entry: 400 Skipping LOD load, lodIdx is negative: -1261039100
This state is permanent across the run, ie if models aren't loaded from the very beginning, they won't, until game is closed. Launching it once again, may load 3D models properly (chance is about 30%).
Game is installed as follows: 1. Created new 64-bit wine prefix, set as Windows 10(default). 2 Created separate drive (here E:), pointing to dir in my home dir where all games are installed. 3. Installed DXVK and external libraries: *d3dx11_43, *d3dcompiler_43 installed via winetricks. 4. Installed Original Falcon 4 (needed by BMS for legal reasons) 5. Installed Falcon BMS 4.37 update 3 (using full installer, direct to latest version, no updates on older release)
Game was run with --mono switch to get debug logs.
System specs; Hardware: CPU: Ryzen 5 5600X; M/B: MSI B550-A PRO; RAM: 16GB DDR4 Patriot Viper 3733MHz CL17; GPU: Saphire Pulse RX5700XT BE OS: Fedora 38 x86_64; kernel 6.5.9-200; libdrm-2.4.117; mesa-23.1.9; wine-8.19; dxvk-2.3
Wine is installed from Fedora rpms, issue is present both in X11 and Wayland session. Using wine build-in D3D11 wrapper instead of DXVK makes no difference. Also it doesn't matter if game launcher (needs extra .Net 4.6.2) is used or game executable is launched directly from command prompt
This issue is not present in previous versions of Wine, last known working is 8.14. 8.15/16 weren't tested as there are no Fedora rpms with those releases.
If needed copy of Falcon4 can be provided, BMS itself can be downloaded for free from project home page: https://www.falcon-bms.com/downloads/
