System Shock Remake (DX12) - Fatal Error!

[schmittie]

Game name and version:
System Shock (Steam) v1.2.1.8898

Mods and mod versions used
OptiScaler_v0.7.7-pre13_20250731 (same with OptiScaler v0.7.7-pre9 (Daria))

GPU
AMD RX 9070

Display Driver
AMD Adrenalin Edition 25.6.3

OS
Windows 11 Pro 24H2

Used automated or manual install?

• Automated
• Manual

If on AMD/Intel and Automated, used DLSS inputs?

• Yes
• No

Also please mention in description which upscaler inputs are used (which upscaler you selected in game settings).

Did you check the Wiki and Compatibility List?

• Yes
• No

Please describe the issue and steps to reproduce it

I start the game with the "-dx12" parameter and use DLSS input (Balanced). In most parts of the games, Optiscaler works as expected, but in certain situations, eg. when trying to exit the first room on Alpha Grove, the game crashes with the error message shown in the screenshot. When NOT using otpiscaler, no errors occur at all.

I have attached

• OptiScaler.log (set LogLevel=0 and LogToFile=true in OptiScaler.ini, zip it if too big)
• Screenshot of game folder (where you placed Opti)
• Screenshot of Opti overlay in-game _(opens with shortcut, default Insert)

Logfile: OptiScaler.log

Save Game for Reproduction: Save 19.zip

Hi,

I don't know if it's possible but could you share a save close to the crash location?

[schmittie]

Hi,

thank you for the quick reply! I attached a Save File. This is just a few steps from the place where the crash occurs!

UPDATE: I also attached the Unreal Engine Crash Files incl. UE4 MiniDump!

Hi,

Just tested, I hope went to the right direction but sadly I can't replicate the crash.

SSRemake-00.00.08.333-00.00.18.710.mp4

Noticed this one in crash logs,

amdenc64 part make suspect about screen recording. If you have that kind of software you might wanna disable it.

Hi,

this is strange, on my machine, the crash happens at ~ 0:03s.

Unfortunately, I don't know what amdenc64 is all about, but I don't use screen recording software.

Even after a factory reset of the graphics card driver, the problem persists. It looks like you are using FSR3 while I am using FSR4, could that make the difference? I'll try it myself with FSR3 and give you feedback...

UPDATE: Changing the Upscaler to FSR 3.1.4 or XeSS doesn´t solve the problem.

[cdozdil]

Do you have any screen recorder or amd relive rtc?

[schmittie]

No screen recording at all.

I have disabled as much as possible in the driver and disabled as many background processes as possible, but still the "Fatal Error! crash...

UPDATE: A downgrade to the latest WHQL driver 25.6.1 did not help either
