so, i got it to work, but not how i thought it would play out.
Now im sure ive played with these settings before so it baffles me, but it works.
I Had to do 2 things 1 minor 1 major. In my Brushify Landscape Material Instance I had a setting called Detail Tiling set to 0.3 which was fine without RVT enabled.
So originally when I enabled RVT I had this very issue of blurry textures. So searched google watched videos and many say convert the TEXTURES to a VIRTUAL TEXTURE.
I did this and nothing helped. So i left them alone.
After all this playing about I decide to just convert them all back as they served no purpose as VT’s. And all of sudden my landscape with RVT on was back to looking great again??? Only think I had to do was change that tiling setting to 2 (from 0.3)
So like huh? how strange that it wasnt working before i converted the textures. Wasnt working after, then converted them back and it works, go figure?
Thanks @ClockworkOcean I did come close with that video messing with some settings but ended up with a more checkerboard pattern of detail/macro/far textures and i couldnt quite figure out how to stop that. But it was close nonetheless!
On epic level settings 100fps 
Edit: On a side note the grass textures HAVE to be virtual on the albedo only tho. Otherwise it goes crazy colour flashes!
