I’m experiencing an issue where Arma 3 is not utilizing my system’s resources adequately. The CPU and GPU usage stays at 20-30% during gameplay, which results in performance problems. Below is a detailed breakdown of the system setup and troubleshooting steps I’ve tried.

System Information:

OS: Windows 11
GPU: NVIDIA RTX 4060 OC
CPU: Intel i5 12600KF
RAM: 32GB
Storage: 1TB SSD
Issue Description:

Both the CPU and GPU usage never exceed 20-30% while playing Arma 3.
This issue persists whether or not I use mods. Disabling all mods did not resolve the problem.
Troubleshooting Steps Already Tried:

Compatibility Settings: I managed to temporarily resolve the issue by setting compatibility mode to Windows 8 for the game’s executables. However, the fix stops working after rebooting the PC.
Game Reinstallation: I was recommended to uninstall the game, clean the registry using CCleaner, and reinstall Arma 3. Unfortunately, due to a slow internet connection (600 KB/s), downloading the game and its mods would take over a week, so this is not a viable solution for me.
Graphics and Configurations Tweaks: I modified the arma3.cfg file with the following settings:
GPU_MaxFramesAhead=1
GPU_DetectedFramesAhead=1 I also disabled VSync, lowered HDR and PiP settings, and adjusted view and shadow distances. None of these changes resolved the problem.
Request: Could the development team investigate why the game is not fully utilizing my CPU and GPU, and suggest a solution? I would greatly appreciate any further guidance to fix this issue.

Thank you for your time and support.
