DLAA counts as native resolution; DLSS, FSR and XeSS upscaling never do. A ray tracing setting without a readable on or off value is read as on.

Gaming benchmarks

Every card ran the same games at the same settings on one test system: AMD Ryzen 7 9800X3D, DDR5-6000 MHz RAM. The index sets the fastest card to 100 using the eligible test runs.

1440p native and upscaled rendering

  1. GeForce RTX 4080 100 index, fastest
  2. GeForce RTX 3080 65.2 index, 35% behind fastest

Index uses 10 matched test runs (8 native, 2 upscaled); fastest card = 100.
