Low FPS due to Gfx.WaitForPresent when a game runs on 8 displays
Experiencing huge FPS drops the more displays you run the game on.
It drops proportionally as you activate more displays, even though Camera.Render is not increasing so much: 6 ms for 1 display up to 13ms for 8 displays.
The problem is in Gfx.WaitForPresent that takes 50-80% of frame time when all displays are activated. There is no such impact when only one display is on.
VSync is off both in Quality Settings and in Nvidia control panel.
Also I dont see the problem in the editor, as the Camera.Render time just increases proportionally from 6ms to ~35ms when adding 8 Game tabs. Gfx.WaitForPresent only occurs in the Windows build.
