It has issues with the level of detail of some elements
The level of detail of some elements is very low.

Considering its a tech demo, the issues with LOD on larger models is quite a problem, But other than that its fine.
Proton 6.21 GE 1
Slight shimmering on some shadows, Larger models such as the statue and the truck look very low quality.

Command line options were: gamemoderun %command% -dx11
If I didn't add the -dx11
flag I would get an error saying that dx12 is not supported and to run the demo without -dx12 or -d3d12.
During more graphically intensive scenes the audio would cut out.
There were a lot of issues with LOD's on certain objects, especially larger ones like the fountain and the truck. Most other things loaded in fine.

Runs well until you are about to take over control, then crashes
Seems to run well on first glance, menu loaded up and the first camera sweep works, but then crashes with "fatal error" - it seems right when you are about to take over control. Tried with 6.3, experimental and 6.18-GE - all the same result

3D Models look like bad (like bad LOD version), missing shadow and max brightness for some time
Huge slowdown at first global view (probably loading stuff), and at particles fiesta at the end, nothing else
