Hi there,


I'm experiencing a persistent CPU Frame lock at exactly 31 FPS in s&box. This limit doesn't change regardless of settings (fps_max 0, r_vsync 0) or screen refresh rate (tested both 48Hz and 60Hz). The issue persists in the Main Menu and when entering the Testbed.


System Specifications:


  • Laptop:     Dell Precision 7730 (Mobile Workstation)


  • CPU:     Intel Xeon E-2186M


  • GPU:     NVIDIA Quadro P4200 (Vulkan Driver 582.41)


  • RAM  24     GB


Key Technical Issues Observed in Logs:


  1. FFmpeg/TLS Failures:     Frequent Failed to read handshake response and socket errors when the engine tries to initialize video/streaming components.


  2. Resource Mounting Errors:     Hundreds of ERROR_FILEOPEN: File not found for core resources (e.g., concrete.surface_c, checkerboard.vmat_c) and symlink reloading issues.


  3. Engine Lock:     The CPU frame time is stuck, suggesting an internal engine throttle or a conflict with the Quadro driver's power management.


Steps Taken:


  • Verified game files and cleared cloud cache.


  • Disabled NVIDIA Power Management features (BatteryBoost/WhisperMode).


  • Attempted to bypass the UI by entering the Testbed, but the 31 FPS cap remains constant.


I have attached the full console log. Given the Workstation hardware (Xeon/Quadro), is there a known engine limitation or a specific launch parameter I should use to unlock the frame rate?

CPU/GPU Mismatch: GPU is hitting ~16ms (62 FPS) while CPU is locked at ~32ms (31 FPS).


Major Exception: Console confirms System.IO.FileNotFoundException for /volumetrics/cloud01.nvdb.


Resource Failures: Huge amount of ERROR_FILEOPEN for basic surfaces and shaders (e.g., concrete.surface_c, retro.shader).


Hardware: Confirming this on Xeon E-2186M / Quadro P4200
