Oblivion Testing

[VagabondAzulien]

First: thank you for this script.

I am working on getting Oblivion working with mods using Mod Organizer 2. It appears to be completely untested as of yet. As per the README, I am opening an issue to track any progress.

System

Arch Linux, kernel 5.6.14-arch1-1
Intel i5-6500 3.2GHz
NVIDIA GeForce GTX 1060 6GP, drivers version 440.82-17
16GB Ram

Game is installed on an SSD.
Steam version 1.0.0.62-1
Proton version 5.0-7

Tested

• Installing Mod Manager 2 and OBSE via this script ✔️
• Manually downloading and installing a mod from Nexus ✔️
• Running Oblivion through Mod Manager 2 with no mods ⚠️
• Running Oblivion through Mod Manager 2 with mods ⚠️

Results

Installation went smooth, after #61 was resolved. Had to set arguments due to my Steam library not being at the default location (--proton-libdir /path/to/Steam/dir). Once installed, tried running Oblivion without mods and the game started. Exited at main menu, downloaded a few mods, and tried again. Game started successfully, with modifications apparent (DarNified UI, specifically). Once confirmed game works with and without mods, jumped into starting a new game. Immediately noticed performance issues. After about 5 minutes, game freezes. Tested both with and without mods; same results. I believe there's a memory leak, perhaps tied to OBSE. I confirmed no performance problems when running the game from Steam directly (using the same Proton versions).

I will continue to investigate. I have no experience with OBSE, Mod Manager, or Lutris. I have limited experience with performance testing. Any suggestions welcomed.

You said you think the problem might be related to OBSE. Do you experience the problem if you run Oblivion from within Mod Manager instead of OBSE?

[VagabondAzulien]

Selecting Oblivion instead of OBSE, then clicking "Run", I experience the same problems: performance drop, as well as freezing after roughly 5 minutes. One other thing I just noticed: I don't think running it through Mod Organizer plays any of the music. All other sound seems to work fine though.

Exit Steam and start it in debug mode with the following command:

PROTON_DUMP_DEBUG_COMMANDS=1 steam

This will create a directory containing debug data in /tmp/${USER}_proton, send me the contents of the run file. This should allow me to check for differences between the Lutris launcher and Steam.

Here's the gdb_run file: https://gist.github.com/VagabondAzulien/cc42446174b36733b500184499690a0d

Additionally, here are the logs from my recent run of Mod Manager, using the OBSE run option: https://gist.github.com/VagabondAzulien/088c86167abf5500c15d4a5be352566a

From these logs I see that your Steam Client was installed to a different path than the expected one ($HOME/.local/share/Steam instead of $HOME/.steam), this is breaking the creation of LD_LIBRARY_PATH in the launcher script because of bug #72. When the mentioned bug is fixed, so should these problems.

[VagabondAzulien]

I can confirm that after manually overriding the LD_LIBRARY_PATH in the run_proton configuration that things seem to be performing much better: the game runs without the performance issues, and the music works.

I literally took the LD_LIBRARY_PATH from the gdb file above and replaced the library path in proton-launcher.sh. I haven't tried to construct it from other variables/information.

[rockerbacon]

Release 2.7.1 should have fixed all instability problems.

All that's left is to confirm whether or not ENB works. Have you tried that?

[VagabondAzulien]

I haven't tried ENB, nor had I intentions to. Looking into it briefly, it seems that ENB isn't very well supported for Oblivion to begin with. If I get some free time, I'll give it a shot.

As for additional mods, I've mostly had success. I've had problems with a mod called MenuQue working properly, and am looking into it. Been a bit busy though, so testing is slow.

[VagabondAzulien]

Getting MenuQue to work required a small modification:

• Go to Tools -> Executables
• Modify Oblivion, and select the Force load libraries (*) option.
• Click the Configure Libraries button
• Assuming there are no entries: click Add Row:
  • In the first box, select the executable for Oblivion (probably just Oblivion.exe)
  • In the second box, select the DLL file for OBSE (probably obse_1_2_416.dll)
  • Finally, make sure the checkbox to the left is checked.
• Click OK, then Apply, and exit out.

Moving forward, run the Oblivion option and not the OBSE option.
