Symptoms

The tutorials video are broken and shows a placeholder instead. I believe this is due to MF codecs.
Additionally, there are a lot of heavy lag spikes on my side, but I've been told that's probably because the steam version just came out so shaders are compiled at runtime on the fly instead of pre-computed. Still writing it here in case that's not the real issue or if someone have the same problem.

Reproduction

Go into the Options->Tutorial section and select any tutorial.

Start with steam-1003590.log and the linked system information report, then reproduce the issue from Options -> Tutorial by selecting a tutorial. Done means determining the cause and confirming that tutorial videos render instead of showing a placeholder; separately verify whether the reported lag spikes are part of the issue.
