saw someone on our tekkenph fb group can run this game on his mid end laptop with mobile gpu specs were i5 u5100/u6100 something like that 8gb of ram and geforce 940m not even a gtx one but on a very low settings. It can also run on this portable handheld called GPD WIN Intel Z8700 Win 10 OS Game Console with the lowest settings too, the price is almost a bnew ps4 but the thing which is admirable on this device is you can carry it and play tekken 7 on the go.
Update : new specs working i3 u7100 / 4 gb ram / geforce 940mx mid settings with a slowdown on loading.
