Summary
Highlights
Begin by turning off VSync under the video tab and checking for aim smoothing under the keyboard and mouse tab; disable it if your aim feels floaty. Keep window mode on full screen, match resolution to your display, and turn off the frame rate cap unless streaming or recording, in which case set it slightly below your actual FPS. Max out Field of View to your preference.
The 'Advanced Video' tab offers significant FPS changes. Moving from 'Highest' to 'High' provides a substantial FPS boost (e.g., 50 FPS to 70 FPS on a 3080 Ti). For most systems, 'High' is recommended. Lowering to 'Medium' or 'Low' presets offers minimal additional FPS gains and can introduce visual artifacts, especially with upscalers.
Using resolution scaling options like Nvidia DLSS, AMD FSR, or Intel XESS can greatly improve FPS. Nvidia DLSS on 'Performance' looks excellent, while FSR and XESS might appear blurrier/shimmery. For Nvidia GPUs, set anti-aliasing to Nvidia DLSS and resolution scaling to 'Quality' (or anything but DAA) for a significant FPS boost without major visual degradation.
Most individual graphics options have a minimal impact when changed alone, but their combined effect is noticeable. Screen Space Ambient Occlusion (SSAO) on 'Low' is recommended for a balance between visuals and FPS. Anisotropic Filtering and Texture Quality had no performance impact on the benchmarked system, but can affect VRAM-limited cards. Shadow Quality on 'Lowest' yields a small FPS increase, and Environmental Detail Distance on 'Medium' is generally fine. Foliage Distance is an outlier; setting it to 'High' provides an FPS boost from 'Highest'.
Beyond performance-related settings, turn off Motion Blur for better target spotting. Chromatic Aberration can be disabled to reduce visual clutter during intense moments. Enable Nvidia Reflex (on 'Boost' for low-powered CPUs) for reduced input latency. UI Refresh Rate has no significant FPS impact.
In the 'Sound' tab, set 'Listen Mode' to 'Headphones' to better distinguish footsteps from loud explosions. Disable 'Mute when not focused' if you frequently alt-tab. Under 'Social', change 'Crew Chat Voice Input Mode' from 'Open Mic' to 'Push to Talk' to control when your teammates hear you. Proximity voice chat remains separate and can be useful for hearing nearby enemies. Background Noise Suppression should be light or off if using push-to-talk to save CPU resources.
There's no single 'magic bullet' for performance; FPS gains primarily come from upscaling and a cumulative reduction of settings. For mouse input issues, try streaming your entire screen instead of just the game, and disable Discord/Steam overlays. Consider using the web version of Discord. Performing a fresh system reboot before gaming can also improve performance. Expect further optimizations and graphics driver updates upon the game's full release.
