So. It was PCI-E x1 mode?

2x. It has a setting for 4x but the main port is 16x.

Not sure what this screenshots means.

I mostly use mpv. I tried EVR-CP in MPC-HC and I still have problems.
I don't think I have any video enhancement features enabled in my video card.
I use 120Hz, no gsync. I tried setting it so it only doubles the frames in the video
but I still have this problem.

Edit: I solved this issue. My graphics card was in the wrong PCI-Express port.

this's strange
first of all ensure that video renderer is MPC-HC is set to EVR-CP
turn off all video enhancement features in the video driver

what is the screen refresh rate? gsync / etc in use?

I get very low performance in regular h264 files in both mpc-hc and mpv. h264 10-bit and hevc seem fine. I have hardware acceleration turned on.

i5 2500k @ 4.2GHz, GTX 970, Windows 10 (1709), latest SVP Pro.

My SVP index never seems to exceed over 0.7 in 1080p videos and my CPU usage seems to cap at around 60% (screenshot 1). In 480p videos my SVP index goes to around 1.3-1.5 (screenshot 2).
