If you read the discussion on steam, you will find out, that the auteur did stop updating this mod by ETS version 1.32 a is not going to continue. I've used this for a long time and it worked very good. But still not had the time to test it with 1.35.

As we say in Holland, there always will be a boss above a boss

there is such a function in Steam. Easily to find also.

I overclock only sligthly, nothing very agressive. I just have to for those three hungry monitors

It may be something wrong with overclocking, i found out today. By disabling MSI afterburner the framerate dropped with 10 FPS (so stil around 110 max.), but no more crashes. So i think, i have to find different settings in afterburner to run without crashes.

DX11, two 1070Ti in SLI, three 1080p monitors, 5760x1200 resolution. Framerate between 90 and 130 FPS. In two hours gametime about 2 crashes. Thats very different from DX9, where i had difficulties reaching 60 fps outside cities, being between 30-40 fps inside cities. So now i play mostly ATS, ETS2 ...

I don't see enough info here to localize your problem. I can only tell you, that you don't need any second device (shifter) to make your wheel work. I use the T500RS, that uses the same firmware, and it work's just fine. My son got a T150pro from me, and that works also fine. What we did found out, ...

When it's ready, i guess

I would love to see the guys cooperate on one fabulous thing instead of building two different al alone... Wishfull thinking, i know...
