Hello everyone,
Now this is my first time ever posting on a form of any kind, but I am having the same problem with my game of KeeperRL.
And before you ask I am running Win 10 With Mobile Intel(R) 4 Series Express Chipset Family (Microsoft Corporation – WDDM 1.1).
I can confirm that that is the latest set of these drivers for that set of chips. I have looked every were to find an update but there is nothing out there. I would love to play this game I have watched many play it, mainly the YouTuber by the name of SplaterCat, do take your time though I know working out bugs can take sometime.
