Quick answer
Mission essentials
- Establish a stable native baseline first
- Lower expensive lighting before texture clarity
- Use upscaling only after checking image stability
- Change one setting group at a time
Build a repeatable baseline
Test the same busy section of a full server, cap background applications and record frame rate before changing settings. A repeatable comparison is more useful than copying a preset from different hardware.
Prioritize battlefield readability
Keep textures and view detail as high as memory allows, then tune shadows, effects and advanced lighting for consistency. Avoid aggressive sharpening or frame generation until your base frame rate feels responsive.
