I run the Vive with the lowest settings in game and still have big stutters. It might be partly due to bugs in Steam VR and the new resolution scaling function.
I can manage to drive two jobs before having to retire due to a weak stomach
I use ctrl+num3 to prevent the rubber banding effect too.
Since last build of ETS2 the rendering has improved fortunately.
Developer SCS have said in a stream last month they're working on porting the engine to DX11 and that could happen sometime this year. DX11 should give another boost to the rendering.
I can confirm that CTRL 1 and CTRL 3 are the way to go. It will get rid of the rubber banding effect. I use CTRL 1 most of the time and in some city areas I switch to CTRL 3. I run with SS 1.4 in the ini file and medium to high settings. It took some tweaking but the game sure is worth it.
