Slow, system-crippling startup of D3D11 players with DisplayPort monitors
1) Locate a machine with an NVIDIA graphics card where the monitor is connected via a DisplayPort connection.
2) Build a Windows Standalone player that is set to use the D3D11 API only.
3) Launch the player.
4) Observe that between double-clicking the executable and seeing the launcher appear, some time passes - anything from 2 seconds to 30 seconds - during which the entire OS is sluggish, almost to the point of being unresponsive.
5) Compare the behaviour to the same project built to use D3D9 - no delay is observed.

While DX11 is fixed in 5.3
I can still reproduce this with GlCore on Windows.

More info:
The game Rust (uses Unity) has the same issue. If you start it using DX11 (default) it chugs. Start it with DX9 and the resolution picking dialog appears in just a couple seconds.

I can confirm this.
I changed the cable on my monitor from DVI-D to DisplayPort and my DX11 project takes about 15 secs to show the resolution picking Unity dialog. Mouse cursor is sluggish and CPU is pinned during that time. I switched the project to DX9 and the problem goes away.
