I read the Nvidia white paper, it says the performance improvement over 1080 TI is 2x. But all resources I can got online indicate the performance improvement is just 30%. Why is that difference? What is the actual improvement? Because if it is just 30% faster, why spend more 60% money on 2080 TI. Does nowadays commercial render engine(like Octane) fully utilize the new hardware features?
Anyone who has tried 2080 Ti can give a performance report on that?
