A lottery with increasingly excellent odds of winning for AMD Radeon users.
nVidia left out hardware schedulers from Pascal back in the design phase, before nVidia realized AMD had pressured Microsoft into incorporating DX12 (essentially Mantle) into Windows 10. By the time nVidia knew this, it was too late to change Pascal. nVidia hoped the adoption of Windows 10 would be slow, but Microsoft gave it away for free for nearly a year.
So much for nVidia's plans. They were hoping to milk not-so-bright nVidiots over a longer time frame, before they lost the gaming war with AMD (an inevitability, as AMD now has >25% of the overall x86 gaming market), but AMD had other plans, and Microsoft is a willing accomplice. Now nVidia is pushing like mad to get into self-driving cars and high performance computing because their days of making the big $$ from add-in PC gaming GPUs is coming to an end, much like the add-in sound card days for SoundBlaster.
Once AMD releases Zen APUs with Vega graphics and their new memory fabric, the market for the mid-range add-in GPUs will begin to evaporate just as the low-end add-in GPU board market mostly has. nVidia is getting painted into an ever-smaller unit volume market at the high-end, which is ironic, really, considering what a rip off the price-performance proposition is for a $600 GTX1080. Why anyone continues to funnel that kind of money to the Green Goblin is beyond me. I never spend more than $300 (maybe $320) on a graphics card, and that's my hard limit.
