❗ Monster Hunter Wilds Crashing on Ryzen 5 1600 (Zen 1) — Exception C0000096 — Likely Unsupported Instruction

[unsword]

Hey all — I’m dealing with consistent game crashes that appear to be related to CPU instruction compatibility, and I wanted to both raise awareness and report this in detail.

System Specs:

CPU: AMD Ryzen 5 1600 (Zen 1)
GPU: NVIDIA RTX 4070 (Driver: 528.83 – March 2025, WHQL)
RAM: 32GB DDR4
Storage: Fast SSD
OS: Windows 10 Pro 64-bit
Display: Ultrawide (3440x1440)

Crash Behavior:

The game consistently crashes to desktop with no error message. Sometimes it takes 30–40 minutes, sometimes just 2. Once REFramework was removed, I started seeing the proper Capcom crash reporter, and the crash log always shows:

ExceptionCode : C0000096
ExceptionAddress: 0x14BEECDB2
Faulting Module : MonsterHunterWilds.exe
That code (C0000096) points to a privileged or unsupported instruction being called. From what I’ve gathered, this could be a result of the game trying to execute instructions that are only available on newer CPUs (like AVX2 or FMA3), which Zen 1 doesn’t support.

What I’ve Already Tried (in full):

Software & Mod Fixes:
Fully clean uninstalled the game

Manually deleted leftover folders from:
SteamApps/common
%AppData%
Documents\My Games\

No REFramework or mods reinstalled
Removed all autorun/ scripts, .ini configs, and Lua files
Verified files multiple times
Ran the game with -dx11 launch flag
Tried both fullscreen and borderless windowed
Tested with both ultrawide and 16:9 resolutions
Disabled all overlays (Steam, NVIDIA, Discord)
Set graphics to Low/Medium
Let game idle and also ran live hunts to trigger crash conditions
Hardware & System Settings:
Updated GPU drivers (WHQL)
Monitored system (CPU, GPU, RAM, VRAM) — no overheating, no spikes
Tried on High Performance power plan
Disabled background apps and cleaned startup

Conclusion:

Based on all this testing, the game appears to execute CPU instructions not supported by Ryzen 1000-series (Zen 1). This wasn't always an issue — crashes likely began after a recent patch that introduced new code paths. If the game isn't doing proper CPU feature checks before calling these instructions, users on Zen 1 chips (still common!) will continue to crash hard with Exception C0000096.

Request to Capcom:

Please consider implementing a CPU feature check or fallback for users on Zen 1 or similar older CPUs. At the very least, updating the system requirements to reflect AVX2 or similar needs would help players avoid this frustrating issue.

Happy to provide full logs, crash dumps, or testing help if needed.

Any messages you want to address to Capcom directly is best done via email [e-mail] or [e-mail]

Well, I mean yeah, you're not gonna get an official response here. And also, need I even mention the bottleneck of the century you are dealing with? We can all gather what the issue most likely is.

Bro, you can probably support a better CPU if you upgrade your motherboard Bios. You can buy a Ryzen 5 5600 for around $100 USD. If it's an OEM motherboard, you're probably screwed though. But you can always look up your motherboard model, and see if there are any bios updates that provide support for the 5000 series CPUs.

I'm using a Ryzen 7 5800X3D in an x370 motherboard, which is from 1st gen Ryzen. It benchmarks the exact same as it does in a newer chipset.

some things seem to be less obvious than others, surprisingly.
i've already sent them the report, posting this here for community, should response come out i'll post that too, i've got 100 hours in the game, the changes that really put a throttle on the CPU began after the update. if they do confirm they're now using AVX2 there are workarounds that can be done.

funny you should mention that specific cpu, its scheduled next on my upgrade list, but its still few months away

[MiraiKishi]

Did you even read the minimum/recommended specifications section of the store page?

The MINIMUM required CPU is the Ryzen 5 3600.

You're 2 generations out of spec.

I will say, you are right about the increase in CPU stress after TU1. There is obviously work Capcom needs to put into the game to make it run better, but yeah, CPU upgrade is definitely something you need for this game. I have a 3600 with a considerably weaker GPU than you, and even I feel like this game is making me wanna upgrade my CPU.

Can you try to roll back to the release directstorage version? It may be related to that update.

Install the MHWilds Benchmark (uses the directstorage version of the release of the game, that did still support Ryzen 1000 CPU's command-list and feature limitation). Run it and see if it crashes there too. If it does not crash there, copy over the directstorage DLL files over to the main game and see if it still crashes for you.

thats lowkey kinda genius,
the benchmark works fine, on forced max settings with no framegen i got a good score with 45 average fps

ill try swapping the files now

yep that seem to have worked out, just had an hour long session multiple hunts across multiple biomes, no crashes. you're a legend.
for anyone reading, grab dstorage.dll and dstoragecore.dll from the benchmark version of the game and slap it into the current mhwilds main folder version if you're having this issue running Zen 1 CPUs, this entirely explains the C0000096 exception crashes.

np, yw! Have fun & a good hunt!

bon je reviens au nouvelle cela ne fonctionne pas toujours les mêmes crash avec les même code erreur par contre j'ai remarqué que dans les fichier du benchmark les fichiers nommée rechunk001 et 002 ne sont pas présent serait t'il possible que ca vienne de ces fichier
