Thank you for this wonderful AI-generated bug report without any logs that could actually be helpful! We don't want any actionable information anyway and just love being talked to by bots!
Anyway, our DXGI reports the budget that the Vulkan driver gives us; if it's only 8GB on a 12GB card then maybe close some applications that are eating all that VRAM. Games shouldn't crash due to low VRAM, but that's probably not our problem to begin with.
Sorry about that! I'm from Russia and my English isn't great, so I used an AI translator to structure the dump output. I'm a real player just trying to help report a reproducible issue.
To clarify regarding VRAM:
I can provide proper logs — please let me know if you need PROTON_LOG=1 or specific VKD3D_DEBUG variables. I will reproduce the crash with logging enabled and attach the log file here.
Thing with any sort of AI usage is that we can't be sure if it's just a very verbose translation or if it's just made-up bullshit, and based on the history of AI reports we have to assume the latter, especially if they follow a certain structure and make assumptions about the root cause of any given issue.
A standard Proton log (i.e. PROTON_LOG=1) is always a good start.
Since you don't like the use of AI and I can't control how it alters my words, I will write my response in Russian. But first, thank you for the quick reply, and I apologize for my oversight in not checking the Proton logs right from the start.
Прикрепляю 2 файла с полного лога: я срезал последние 300 строк и отдельно отловил ошибки, ибо остальное не имеет смысла. Кароч проблема в самой игре, движок игры полез в недоступный адрес.
Вот блок ошибки:

Теперь буду просто ожидать ответа от поддержки игры.
И так чисто от себя: нелюбовь к ИИ понимаю, сам веб-разработчик и имел дело с вайб-кодерами, но я просто редакнул через ИИ ответ, я понятия не имею, что он там напридумывал.
As a side note in regards to translations then it is of course understandable that it can be needed if you aren't proficient and i don't think anyone here denies that.
I would suggest instead of using one of the new AI's to just write the report in your original language first and then translate it using a simple old style translator service like Deepl or Google Translate before posting. The issue template should hopefully also be able to be somewhat translated to your local language beforehand so you know how to fill it out.
That should decently enough get the issue across, if described properly before the translation, without adding all the extra noisy padding that LLM's can have a tendency to do.
Unless some of the technical details or requests in the template or your description gets lost in translation ofc. But we could always ask for clarification then. (Maybe also note that a translator was used)

Retail_14.1.PATCH.1290778/1291224.PATCH14)Hardware / Driver information
Description of the issue
Following Patch 14.1, the game suffers from reproducible crashes during extended sessions (e.g. Operations /
hm_fortressscene) due to streaming memory pool budget exhaustion.From the engine's exception dump:
Title memory: 5887.6 / 11360.1 MB (3074.4 MB free)
GeomStreaming: 544.3 / 550.0 MB [Utilization: ~98.9%]
TexStreaming: 2065.3 / 2000.0 MB [OVERFLOW: +65.3 MB, 0.0 mips drop]
Reserved memory: 300.0 MB, 0.0 temp [MB]
Total Memory: 8168714240 bytes (~7.6 GB allocated budget under Wine DXGI)
Free Host Memory: 26723504128 bytes (~24.8 GB)
Technical Observations:
DXGI Memory Budget Clamping:
On a physical 12 GB VRAM card, the total memory budget queried via DXGI reports
8168714240 bytes(~7.6 GB). This causes the engine to allocate an overly restricted 2000 MB pool for texture streaming.Allocation Failure / Eviction Stall:
Under heavy asset rotation (
hm_fortress),TexStreamingexceeds this hard budget (reaching 2065.3 MB / +65.3 MB overflow). The engine fails to drop mips (0.0 mips drop), hitting an Access Violation / unhandled exception.Potential VKD3D angle:
Is the memory budget reported via
QueryVideoMemoryInfo/ DXGI adapter query artificially clamped or underreported for this device/driver configuration? A budget override / quirk or proper VRAM reporting might prevent the game engine from constraining its streaming pool to 2 GB.Reproduction Steps
