Not sharp in VR using UE 4.18

I’m creating a VR project in Unreal but when I put on my Vive headset or WMR Headset it does not look as sharp as for example Job simulator, The Lab . What am I doing wrong? It doesnt look very sharp. Close up things look better but farther way does not.
I’m using a 1070 video card with an I7 PC . I know it’s not my headset cause the other things look great.

Please help my problem must be in Unreal.I’m using 4.18 version.

thanks

Hello , there are known issues with WMR headsets in 4.18 that are resolved in 4.19

As for Vive, try using the console command “r.screenpercentage 150”

In 4.19 this command will change to vr.PixelDensity
