(Newbie here) Lagging issues in Furioos

I uploaded our exe file on Furioos after packaging our project with the pixel streaming plugin turned on.
However we are dealing with some bad lagging issues once we upload it on Furioos
Would there be some other options in Unreal Engine4 that can be changed to a lower the resolution of my project?
I made sure that the motion blur option is set to 0. It definately improved, but still lagging.

This is the link of our project in furioos

Thank you!
