I've tried here, but I can't reproduce the problem with 60Hz FSE. How can I reproduce the problem? How do I even know that it's playing too fast?

i can make a file with audio but if it runs to fast you will get an black screen or see the last screen for the rest of the playback time after the last frame is rendered.

i just managed to reproduce this on my dual monitor system the file was finished after ~ 20 sec with bilinear chroma resizing so it looks like madvr fse with smoothmotion plays HFR files as fast as possible. so you may need a gpu/cpu that can run 1080p at over ~ 120 fps to reproduce this error.
if it runs to fast all queue drop except present frames in advanced. and i get ~ 100% cpu usage.

i added a log but i think it is way easier to reproduce this.

edit: don't add ~ and a number without a space!

The speedup problem is caused by the GPU not being fast enough to render 120fps + SmoothMotion FRC. If you dial down the algorithms so that the GPU gets fast enough, playback should run at the normal speed. I'll keep this bug open to be fixed at some point in the future, but I consider it very low priority atm.

This also occurs for me with 60p content on 23Hz, sometimes even in Windowed playback. Sometimes I need to switch to FSE to make the problem appear.
