When you use one of the Supersampler technologies the game renders a lower resolution image and then your selected upscaler uses AI algorithms to increase the resolution artificially to your native resolution (or whatever specified for Windowed mode). Each setting has a fixed percentage; for example if you're running at 2160p native and you are using DLSS "balanced" the internal resolution is 58% of 2160. These percentages or internal render resolutions aren't shown in-game normally so I created a list so users can better compare performance between the various modes. [Note that the percentages listed below were generated when played on a 2160p (4k) display. The percents could change slightly based on resolution.]

• DLAA: 100%
  
• Quality: 66.7%
  
• Balanced: 58%
  
• Performance: 50%
  
• Ultra Performance: 33.3%

• Native AA: 100%
  
• Quality: 66.7%
  
• Balanced: 58%
  
• Performance: 50%
  
• Ultra Performance 33.3%

• Native AA: 100%
  
• Ultra Quality Plus: 76.9%
  
• Ultra Quality: 66.7%
  
• Quality: 58.8%
  
• Balanced: 50%
  
• Performance: 43.5%
  
• Ultra Performance: 33.3%

Unlike the other settings TSR's implementation uses a basic slider to adjust what percentage you'd like to use. Note that while the UI in-game only displays whole numbers internally it actually uses decimals. -Meaning while the UI might say 75% for example, it might actually be at 74.9.
