Used 4K resolution with DRS enabled with 60fps target. This allows the game to scale the res to the max possible while still hitting 60fps target I took 2 sets of screens: one set with equal overclock on the GPU, this is how you can test DLSS in DOOM Eternal to see tradeoffs at a certain fps target. Then another with stock clocks vs overclock to see if a slightly more powerful system can use VRS(Performance) in tandem with higher DRS results to make better looking image.
