Ahh, you beat me to posting this! Well done sir
If these drivers are what they claim to be, then they will improve the performance of all DX11 titles, which is a good thing.
Rome II at the top of the list there has absolutely terrible performance on most hardware, for the CPU in particular but generally bad across the board, funnily enough it is an Intel title.
If improvements are as good as they are claiming, then Nvidia will have done very well, but also look a bit stupid. If these gains could have been made, WHY DID THEY NOT DO THIS BEFORE? We have had DX11 since 2009 after all?
I understand the Nvidia would prioritize improving GPU bound scenarios but a CPU gain for everything with DX11 like this one IMHO should have been thought of and implemented long before now.
If gains are good in this driver I wonder how, or if AMD will respond to it.
