I recently just purchased an Asus 1070 ti strix, upgraded from a 1050 ti. I ran cinebench on the 1050 ti and go 101 fps, but when I run it on my 1070 ti I only get 95 fps and my GPU usage during the test is only 30%. Running PUBG all ultra settings I only get on average 70-80 FPS, it goes from like 120 down to 30 FPS sometimes. I have an i5-6600 CPU and I have made sure that all the drivers are updated, I'm not sure if my card is just a lemon or not.
