So, tiling and immediate mode is done in hardware and hardware is magically suppose to know which one to use. LOL? Of course this stuff works on hardware level, do you seriously believe that I think it's done in software? The decision making which of these hardware implementations are used is however done in SOFTWARE. And clearly, AMD has massive issues with drivers at the moment. So, which part of it you don't understand now?
NVIDIA is not selling Titans in stores to have a higher margin and keep it all for themselves. C'mon, it's business 101. They don't have time to sell every GeForce by themselves, but they sure can handle sales of just 1 type of card...
Well you could buy other pascal FEs on geforce.com store too(currently all of them are out of stock)... Ain't vega FE should use the same driver as upcoming RX Vega will use(by amd on that reddit ama)? So probably we will see performance uplift for that too at least at the time RX Vega releases.
The Frontier Edition was designed for a variety of use-cases like Machine Learning, real-time visualization, and game design. Can you play games on Frontier Edition? Yes, absolutely. It supports the RX driver and will deliver smooth 4K gaming. But because it is optimized for professional use cases (and priced accordingly), if gaming is your primary reason for buying a GPU, I’d suggest waiting just a little while longer for the lower-priced, gaming-optimized Radeon RX Vega graphics card
