NVIDIA's lower input lag results with the 'Ultra' 'Low-latency' mode vs AMD's Anti-Lag is presumably due to the Ultra mode effectively being 0 pre-rendered frames (whether or not there is additional optimization that yields tangible benefits I don't know). AMD's stock Anti-Lag configuration is certainly at least 1 pre-rendered frame (I think it might even vary according to the driver's game profile). So it's quite disingenuous to compare the two Anti-Lag features - AMD's Anti-Lag is designed for GPU-limited scenarios where you want maximum frames whilst lowering input lag, NVIDIA's 'Ultra' 'Low-Latency' mode is for lowest-possible latency scenarios. It would be nice to see AMD add a similar feature themselves (specifically the ability to set pre-rendered frames down to 0 in the AMD game profiles and additional focus on achieving the lowest possible latency).
Given that you can actually set pre-rendered frames using regedit with AMD cards (Main3D value under 'UMD' key, use RadeonMod - 3 values to change) it would be interesting to see some actual button-to-pixel latency comparisons between NVIDIA's Ultra solution and AMD Main3D @ 0 (specifying Anti-lag state).
