Everyine has there own opinion when they most likely havent used a pentium on the program itself

I belive it would work fine the game itself isnt a cpu or gpu hungry game pentium is a good processor but is out of date
I used to use a athlon single core on a compaq with 6gb
Of ram and could play minecraft and borderlands 2 with max
And have 50+fps (it wad a laptop!!!)

They will release a demo version download that
And test it and if it lags try and change the quality
