i know this is old but the link is down, would it even still work? or is there a newer fix?

980ti hybrid sli setup

32gb of ram

game installed on a 960 evo nvme drive

i play at 4k and for like 20 - 30 minutes it looks so good. then it starts to stutter and the frame rate tanks. i have to drop it to 1080p to keep playing. or sometimes it just crashes, i thought it was my pc.
