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 the same test system. The index sets the fastest card to 100 using the eligible test runs.
