Vray 3.5 RT on GPU very blurry

[perry2016]

Hi guys,
what is wrong with vray RT on GPU, it only produces blurry images, with the CPU no problem .
I tried one scene, left half with GPU (2 x Nvidia 980TI update drivers) and the right half with CPU : left blurry and right sharp, how come

And yes i tcheckes the DOF & motion blur in the camera
Thanks!

There's an option to downscale textures when using GPU just under the "Render Servers" button. It's the dropdown named "GPU textures". Check if you haven't chosen "resize all textures" and that you haven't put a low resolution in "GPU texture size". If you have, increase the resolution and try again. Or maybe even try selecting "full size textures" from the "GPU textures" dropdown.

Writing here so everyone can see it.

You are using Catmull-Rom filter which is not supported in RT GPU. I will make a note for displaying a warning for unsupported filters when using RT GPU.
