FSR2 Implementation Causing Sudden Crash
My research shows that this issue has been affecting many others since the game launched.
Platform: PC, Steam
Hardware:
CPU: Ryzen 9 7900X
GPU: Nvidia RTX 4090, Driver version 591.44
RAM: 32 GB DDR5 @ 6000 MT/s
Storage: Corsair MP700
Display mode: Borderless @ 165 Hz refresh rate
Summary:
Battlefield 6 repeatedly crashes to desktop in the middle of gameplay with no in game error dialog. Windows Event Viewer shows Application Error 1000 for bf6.exe with ExceptionCode c0000005.
WinDbg analysis of the Frostbite minidump shows an INVALID_POINTER_READ inside bf6!ffxFsr2ResourceIsNull, which appears to be part of the FSR2 integration. This occurs even though FSR is disabled in the game settings.
The faulting instruction is reading from address 0x11 because RAX holds the invalid value 0x1 at the time of the crash, which implies an invalid or corrupted FSR2 resource or handle.
Steps to reproduce:
These are my current conditions. Exact steps may vary, but the pattern is consistent:
1. Launch Battlefield 6 through Steam.
2. Verify in video settings that FSR is set to Off. No upscaling in use, resolution scale 100 percent.
3. Join any multiplayer match.
Play for several minutes. At some point mid game, the client abruptly closes to desktop with no error dialog.
Event Viewer logs Application Error 1000 for bf6.exe, and Frostbite creates a minidump.
Expected result:
Game remains stable during match.
No access violation or crash in bf6.exe.
Actual result:
Game suddenly exits to desktop.
No in game error message.
Windows logs an access violation in bf6.exe.
Frostbite minidump shows an invalid pointer read in bf6!ffxFsr2ResourceIsNull.

Interpretation:
The crash is not in a driver or OS DLL.
The fault occurs inside bf6.exe in a function that the symbols identify as ffxFsr2ResourceIsNull, which is part of the FSR2 code path.
At the moment of the crash, the helper function is dereferencing [rax+0x10] where rax is 0x1, which leads to an invalid pointer read from address 0x11.
So the immediate and reproducible technical cause is:
Battlefield 6 is passing an invalid or corrupted FSR2 resource or handle into ffxFsr2ResourceIsNull. That function then dereferences a field of this invalid object and reads from address 0x11, causing a c0000005 access violation in bf6.exe, even when FSR is disabled in the video settings.
Workarounds tried:
Verified game files in Steam.
Disabled all overlays (Steam, Nvidia, Discord, MSI Afterburner).
Clean installed GPU drivers.
Tested with FSR explicitly disabled in game settings, resolution scale 100 percent.
Tested different display modes (Fullscreen vs Borderless).
Ran DISM and SFC.
No CPU, GPU or RAM overclocks, or tested with all overclocks and XMP disabled.
Request:
Please investigate this crash bucket and the FSR2 path in Frostbite for Battlefield 6, specifically the handling of FSR2 resources around ffxFsr2ResourceIsNull, since it is possible for that function to be called with an invalid resource pointer (RAX = 0x1 in my dump) even when FSR is disabled in the user settings.
Attached is the dump file.
