Topic: 4k playback choppy and slowed down

Hi there, I'm using SVP with MPC-HCx64 or VLC and running the files through SVP. It works fine for any 1080p file but whenever I try to play a 4k file the audio is fine but the video slows down. GPU acceleration is turned on in the settings but I always see SVP running at 0% on my GPU and about 25% on my CPU. For reference I have a Ryzen 1700 and a GTX 1080 with 16GB RAM. What is going on here? Have tried so many things but nothing works. 4K playback works fine with SVP using MPV player. I am rendering SVP to 144fps as I have a 144Hz monitor.
