[SOLVED] Silent Hunter 3 & Living Silent Hunter 3 Supermod - Steam proton + JSGME question - programming.dev
programming.dev
Hello guys! Recently re watched Das Boot (amazing film btw for those who haven’t seen it, highly recommend) and that inspired me to install my SH3 from steam. The thing is its the first time I’m going to be playing on Linux, and I’m a bit stumped on how I can install the LSH3 supermod. The instructions for the 2022 version of LSH3 state that you simply run the provided .exe (due to this being steam proton I placed it in the game directory but this doesn’t seem to be required) and run it. However I can’t seem to figure out how I can use an existing proton environment to run an executable which is not the actual steam game for that environment. Can anybody help with this? As a bonus question, because this game is quite old there are quite a few mods available for it, and the best way to activate them after downloading (on windows at least) is through JSGME. However I also cant figure out how to install that in the game directory. I have downloaded its installer but dont know how to actually run it. I have included the link to the LSH3 2022 install manual [https://www.lsh3.com/v22/dl/LSH3-EDITION-2022-INSTALLATION_EN.pdf]as well as a screenshot of my game directory with files related to this post circled. Any insight would be amazing!

[SOLUTION AT END OF POST]

Hello again. A few days ago I made the post in the link above which is about getting Silent Hunter 3 working with the LSH3 megamod, and I got a great answer in there to use steamtinkerlaunch to run separate executables just once (e.g. to install JSGME mod manager and to install the actual megamod LSH3).

After playing for a bit I decided I want a little more control over what mods are installed, and decided to switch to the GWX megamod, so I completely uninstalled SH3 and its folder in the steamapps/common folder, and reinstalled it cleanly. Then using wine I ran the 4GB patch so that the game would use 4GB instead of 2GB memory which is required for running many mods. The memory usage can get quite high. After that I loaded all my desired mods with JSGME.

The game starts fine, and I can do all the training missions and the single missions, but I cant start a campaign. After the loading bar for entering a campaign patrol fills up, there is a delay of a couple minutes (normal for GWX as during that stage it is loading all its mods and any other mods you have enabled), and then crashes to desktop. This clearly means that it is running out of memory while loading mods. However after running the patcher to increase the memory limit of the executable I get a new sh3.exe file and my original gets renamed to sh3.exe.Backup, which seems to show that the patch has been applied correctly.

Could anyone help me diagnose this issue please?

Thanks in advance!

Edit 1 (SOLUTION): So what ended up working for me was simply making the game run using proton 6.3-8. I did try version 4.3 as well, but that didnt seem to be working that well with the widegui mod I have. Thanks to all who gave suggestions!

Edit 2: Editing to add 2 more things to the solution. Because of frequent crashes while in the career patrol, I ended up lowering the Particle Density to 90 and also do not create any saves while out on patrol. Not sure which of the two actually stopped the crashing, but so far I’ve played for about 20 hours with no crash.
