I really wish they would include some thoughts on the use of HDR since it's one of the biggest visual enhancer. Otherwise really love the analysis. So it doesn't have real time GI after all despite how lighting looks pretty astounding in general. But I think they did make the right trade-off here seeing a plethora of other resource hogging effects and assets made in as a result. The engine sure has a nice balance to achieve such a splendid final result and I wager their second attempt at another open world game would raise the bar even higher.
