Hitting the preview build of Windows 10 in the next few days/months by the time it is optimised. Then it will be live with the creator update whenever that hits.
As for the performance gains, if you on a decent gaming rig (high end i5/i7 CPU with a 900 series or above Nvidia GPU and an SSD) I bet there is going to be very minor changes apart from maybe UWP apps might gain like 5% is specifically coded for Win 10 and its features.
For lower end machines you may see a larger increase in performance as it will kill random HDD background tasks and free up some CPU bottleneck.
It's a good option to add but for people with gaming rigs this is by no means going to be a game changer. Overtime it will hopefully get better as more people code applications with it in mind.
I don't care much about performance increase because as you said I already have a high end pc with SSDs only. I think game mode will help with the reduction of stuttering or hitching in many games, maybe even crashes. That's what I look forward to.
