SuperSampling after recent update

My SteamVR settings seem to have been reset.



I was playing a game and the performance wasn't so good at times. Title: "Onward"

So I was going to lower the supersampling that I have set!



Suddenly I had to find out that the settings have been removed/reset!



"steamvr" : {

"background" : "#0D0D0DFF",

"renderTargetMultiplier" : 2



That's everything to see in steamvr. I remember there was a lot more before the update.



I'm sure I have set the multiplier to 1.4. (Steam automatically set it to 1.39999999 I think.)





How come it is set to 2 now after the update?

Did SteamVR read the graphics card info and then set it to 2.0 regarding the performance?





Now it makes sense to me why the VR Desktop has been so unpresponding and the PC was lagging a bit when watching Steam Videos on the 2D desktop while SteamVR was running in the background. SteamVR drawn a lot performance in 2.0x mode.

And now it makes sense why the dashboard has appeared so sharp to me.



In Afterburner I can see a GPU idle usage of ~21%-22% on 2.0x SuperSampling.

When I set it to 1.4 and restart SteamVR it is 10%-11%. 1.0x results in 7-8% usage.



Why is it set to 2.0 by default?????!!!!! 2.0 does not work out on a GeForce GTX 1070, neither 1080.... ?
