NVIDIA profile audit, 16 September 2026

Read-only NVAPI DRS query completed at 17:28 Vienna. No game/editor was started or stopped; no driver setting, profile database or running build was changed. read_profiles.py binds only an explicit whitelist of initialization, session, lookup, enumeration and read functions. It binds no profile-setting or save API.

nvidia-driver-profiles.json records the raw results:

• rampage.exe and the three exact executable paths (copied D: build, workspace Windows build and stability candidate) all returned NVAPI_EXECUTABLE_NOT_FOUND. No application-specific NVIDIA profile was found.
• Current global profile is Base Profile.
• Four exposed stored settings: preferred refresh rate = application controlled (0); power management = prefer maximum performance (1); Optimus compatibility enabled (1); Optimus rendering enabled (1).
• Of 62 targeted public graphics IDs queried, three exist and 59 return NVAPI_SETTING_NOT_FOUND, including the queried AA, DLSS frame-generation and related override IDs. No forced AA or DLSS/FG override was found through this public interface.
• Profile metadata reports six settings, but public enumeration returns four. The public NVIDIA header contains no Smooth Motion ID. Consequently this audit cannot rule out undocumented/internal NVIDIA App options or claim Smooth Motion is disabled.

During the first running-process module read, Rampage contained nvspcap64.dll version 11.0.9.251 from Windows System32 and nvppex.dll version 32.0.16.1692 from the NVIDIA DriverStore directory. Presence is evidence that these modules were loaded, not evidence of an active effect or a crash cause. A later module snapshot found no running Rampage process; this audit did not stop it.

Installed nvapi64.dll file version: 32.0.16.1692. The finding of maximum-performance power management is concrete; it does not establish a cause for TDRs. No driver profile change is proposed as a proven fix.

Structure layouts, entry-point IDs and setting symbols came from NVIDIA's official nvapi.h, nvapi_interface.h and NvApiDriverSettings.h, downloaded alongside this report for reproducibility.
