Black one screen with multimon mode 4 in beta 1,47

[mrdider]

In beta 1,47 when using mutimon mode 4 (3 the same monitors) when vsync is on in game one monitor is black. When turnoff vsync in game menu and back to "drive" monitor displays normal screen. Then we can change back to vsync on end its work normal, but when we turnoff game (with set vsync on), and again turnon game one screen (in my case always right) it will black.
Graphic settings maxymized (high and ultra) with resolution 5760x1080 amd newest drivers with eyefinity settings.

Try to added separate vsync settings for menu and for driving, because when driving game not use full gpu usage (stack at 70% gpu usage - cpu 60%), and frames around 30-45 fos, but when in end of map, city, company etc, gpu usage jump to 100%, and fps go over 70. But when we turn car about 90 degre it starts to drop fps and gpu usage. Jumping to menu its go to 100%gpu usage and 500 and more fps, back do drive it go down to 70%gpu usage and fps 30-45. In cities in Spain its even worst.
