@Denial - thanks for that. Did not realise they were natively supported through driver + DX12, thought it was another hairworks or other proprietary type scenario. In that case, even more keen to see side by side performance figures of current gen RT vs non RT cores. That being said, the fact that Nvidia are choosing to enable this feature in any way on their lower end cards that do not have the unique hardware for which you are paying a premium for is damaging their own brand, particularly as it has been pointed out that AMD do not support this particularly on their cards yet anyway, so little competition to worry about yet they do this. Why?
