I recently upgraded from a 1050 to a 1080 Ti and I started to see some weird performance in the rendering statistics. No matter what settings I choose, max rendering times always seem to spike at times up to 50ms+, but without affecting average times or dropping frames. GPU queue does seem to jump up and down more often than I expected, but setting it at 16 and presentation frames at 8 prevents any kind of impact from that. Also, if I turn on smooth motion, I almost always get consistent presentation glitches every minute or so, again no matter what settings I choose. I know that my GPU is barely using 60% at these times, so I don't understand all this activity. I'm on Windows 10 1803 4K23p with the latest nvidia drivers going through a Denon x3400h to LG OLED B7. One other piece of strange behavior with both nvidia cards is that I can only get 23.980hz presentation at 4K, while 1080p can get a perfect 23.976hz, and no amount of measuring changes this. Does anyone with a 1080 Ti see this type of behavior?
