Open interactive TapLab ↗Use a hip-fire sensitivity that still allows controlled recoil. ADS multipliers should be tested at the ranges you actually fight.
Start with costly effects, shadows and post-processing reduced, then add quality back if the GPU has headroom.
Use TapLab System Lab to see whether the selected resolution makes your build more CPU- or GPU-limited.
Moderate vibrance can help separation, but map lighting varies; avoid crushing interior detail.
