Maybe try to cap the FPS to 60 using the frame rate target control setting. Hope this helps.
Does this issue occur on older drivers? If not, please report it here.
Is any system component overheating?
Try pressing Ctrl + Alt + Delete when the drop occurs to bring up task manager and check if any system process is using a lot of system memory or CPU cycles.
CPU temp 29c
video temp 32c ..... when playing the game
yes it did happen on older drivers
case temp 20.c
