MGS4 Crashes in various areas at 240fps

[Doomguy1364]

Hello; Awesome mod you've made here! However, I have found that I can reliably reproduce a crash on the last part of the Drebin sequence while the fps is capped at 240.

I am currently using a up to date Arch Linux (Specs listed below) install running the game via proton experimental. Capping the framerate at 60FPS via mangohud at the sequence where it normally crashes will avoid the crash.

I have also tested on version 0.1.0, 0.1.1, and 0.1.2, all 3 versions crash in the same spot; I have also tried using both Direct X 11 (DXVK) and Direct X 12 (VKD3D), on all 3 major versions. The crash will always reproduce on my hardware.

OS: Arch Linux
Kernel: 7.1.11-zen1-1-zen
DE: KDE Plasma 6.7.4
GPU: RX 7900 XTX 24GB VRAM (Mesa 26.2.1-1)
CPU: 7800X3D
Memory: 32GB

Hey cipherxof; I did see that other report but that one didn't mention anything about crashing which is why I opened this one! Didn't mean to clutter your reports, Thanks again for your work!

Oh, right. Someone mentioned it to me on discord that they were crashing, not in that issue. 😅

Just to mention, I had crash on the Eva (big momma) bike sequence, and I had another crash on Raging Raven during a lot of explosions!

My friend who is also on Linux has the same crashes in the same spots with the mod enabled!

Can you upload the crash dumps? They're in SteamLibrary/steamapps/common/METAL GEAR SOLID 4/MGS4/crash_dumps

I can confirm after some additional testing these crashes don't seem to happen at 120fps so they seem to be isolated to framerates higher than that! Here's a few, I normally don't upload dumps for security reasons; However, I feel like these should be isolated (hopefully) to the wineprefix/game process, if there is any sensitive information please let me know lol.

Please re-test with 0.1.3

I retested the whole sequence again on 0.1.3. The APC sequence does play through properly at high frame rates now; However, it still crashes on the same spot (During the last section of the APC section shown in the youtube video). Tested at 240fps, crash log attached.

Also on 0.1.3 the game still crashes during the Raging Raven fight at 240 fps, crash log attached. There could be more places where the game crashes at 240fps; However, I've opted to play at 120 fps in the meantime where these crashes do not happen!

Interesting that I am not getting crashes while playing at 280FPS, also on Linux. I've seen others also reporting crashes as well, so something is up.

Feel free to say no but would you mind adding me on discord or something. Try to get to the bottom of this!

I think the crash logs should be more than enough. I just have to set aside some time to dig into them further.
