could be having problems because it a beta operation system with beta drivers. and not everyone is having problems like you. there is bugs. the driver for windows 10 should be considered Alpha and not beta. seems like people forgotten about driver bugs and crashing in the early vista days. in other news. I did testing with watch dogs. with sli. I got around 20-30fps at 1080p I disabled sli in nvidia inspector and got 60fps. it was super smooth but then the display driver stopped responding and system bsod and rebooted. edit: I have the sli problem in windows 8.1 as well with watch dogs.
