Euro Truck Simulator 2 VR Quality Settings

Euro Truck Simulator 2 VR Quality Settings

Beta support for Oculus Rift and HTC Vive has been available in Euro Truck Simulator 2 for some time. Unfortunately, the beta default quality settings leave something to be desired. With the default settings, the image appears ‘jagged’. The image in the far distance seems often to be a jumble of pixels.

I’ve been experimenting with ETS2 quality settings on the Vive. I think I’ve achieved some significant improvement. If you’ve been struggling with the VR quality settings, hopefully I can help you out here.

This article looks at the most useful settings to change to improve visual quality.

Euro Truck Simulator 2 VR Quality Settings Config File.

ETS2 has some VR specific config options contained within a config file. You should find config.cfg at My Documents\Euro Truck Simulator 2. First of all, make a backup of this file.

Lines that I worked with were:

Vive/OpenVR-specific:

uset o_openvr_independent_timewarp "0"
uset o_openvr_interleaved_reproject "0"

These are really about VR performance consistency. You can experiment with them. Switch either to “1” or both to “0” but not both to “1” and see what works (or feels) best.

Finding the line with uset r_mode, I set it to:

uset r_mode "2160x1200x32x0"

This matches up to the HMD’s native resolution.

Also, make sure MSAA is off. It’s unhelpful for VR in ETS2.

uset r_msaa "0"

r_manual_stereo_buffer_scale.

Now, the real game-changer (pardon the pun) is r_manual_stereo_buffer_scale.

This setting can be used to increase the size of the rendered image. The rendered image is then distorted for VR. It appears the better the quality of the initial image, the better the quality of the VR image. Especially in the far distance.

There’s a trade-off though, the higher you set this, the greater the peformance penalty for your GPU. I found using a GTX 970 that a setting of “1.3” was smooth and looked better. A setting of “1.5” or more made for a very much improved scene. However, at “1.5”, there was judder depending on the scene complexity.

The trick is to find a happy middle ground between quality and performance. With at least at GTX 970 or equivalent, I recommend starting off with:

uset r_manual_stereo_buffer_scale "1.3"

…and work up from there.

Hitting the speed limit.

This setting gave the single biggest improvement in visual quality for me.

The higher the performance your graphics card provides, the higher you can go with this setting. Go too high and you’ll see and feel the framerate dropping off.

You can recover some FPS by reducing the video quality settings in the game menu. Be sure to leave ‘scaling’ at 100% and MSAA off. Most of the other settings yield a little performance improvement. With current Virtual Reality systems being more about the ‘feel’ than the overall look, you can do without some of the bells and whistles.

ETS2-VR-Screenshot
The unedited, unstretched screenshot. The instrument cluster didn’t render for the screenshot but with readable in the HMD in-game.

Due to the way screenshots work in VR, it’s not possible to directly convey how much improvement you can get. You need to try the settings for yourself and make up your own mind what works best.

Certainly, getting rid of the jagged edges in the far distance makes a big difference. This takes the simulator from playable to enjoyable with VR in my opinion.

If you find settings that work well for you, consider posting them in the comments section below.

  1. This made a night and day difference for me. I was considering ditching VR for this game because I felt like I could barely see the scenery. You rock!

    1. Awesome, Thanks! 🙂

      I’m not sure why the settings are so low to start with but there’s lots of scope to get it looking good!

    1. I get even better looks with
      uset o_openvr_interleaved_reproject “1”
      set to 1 for my htc vive.

      the white flickering lines on the road dissapears then.

  2. Im having good results in VR by going easy on the various supersampling (none in steamvr, 1.2 in ATS config file) but using the in game scaling at 200%, which ive read doesnt work in VR, but surely does at least as of Oct ’18. Getting smooth framerate in all but the busiest areas on a 1080 (yeah its a mega card but this game is a hog sometimes)

  3. these are my vive settings as of 11/june/2019 for update 1.35 I have a 1080ti video card but a poor cpu

  4. I am playing ETS 2 with a Vive and a AMD R9 290X and an i7 4790K (stock) but find I got a lot of performance issues even with all the graphics set to low or disabled. I have 100% scaling in-game, custom resolution set to 100% manual in SteamVR, no SteamVR SS (set to 100%) and the game’s config is set to:
    uset o_openvr_independent_timewarp “1”
    uset o_openvr_interleaved_reproject “1”
    uset r_manual_stereo_buffer_scale “1.0”
    uset r_mode_height “1440”
    uset r_mode_width “2560”

    The last two lines are separate unlike in yours and DaveUK’s settings where the resolution can be set on one line and you have added “x32x0” onto the end. Where would I add that bit?

    I also disable SteamVR’s asynchronous reprojection as with it on then my fps is locked to 45 but with it off I can get up to 90fps. Can anyone advise me if I need to change any settings either in the config or SteamVR to achieve better performance? I am using DirectX 11 as well. Thanks.

    1. Obviously, make sure you’ve got a backup of config.cfg before you do anything.

      You could try taking out the r_mode_height and r_mode_width lines and replacing them with a single r_mode line eg:

      uset r_mode “2160x1200x32x0”

      I haven’t tested this and I haven’t used ETS in recent months so it’s possible they’ve modified the way the config file works.

      I believe the R9 290x is around the same performance bracket for VR as the GTX 970 which I first used with ETS. I do I note that you’re using a higher vertical resolution than I originally used (1440px vs my 1200px) This will likely be impacting performance.

      1. Thanks for the reply. I tried replacing the two uset r_mode lines with the one line but the game just overwrites it and puts them back to two separate lines. So I tried just typing in the resolution numbers you suggest for each line instead but without the x32x0 bit as I don’t know where to put that or what it refers to.

        This didn’t seem to change the resolution in the game but when I checked the config file after, the newly typed resolution lines were still there and hadn’t been overwritten back to the old resolution (my desktop monitor is 2560×1440, that’s why it’s a higher number).

        I didn’t notice any performance difference but I think the resolution only affects the resolution of the desktop display rather than what you see in your headset and even then, I don’t think it has any performance impact on your headset’s display if you change it.

        My desktops display is always predominantly a black screen anyway with just a small window in the bottom left-hand corner showing what I see on my headset.

        By and large the game runs ok but when there’s any build-up in traffic or when I get into cities or areas with a lot of buildings and structures, then I notice my frame rate dropping to 70-80 fps or sometimes lower if it’s particularly bad with a lot of stuttering.

        I think the limitations of my GPU and the Vive itself (the SDE alone is very bad on the headset and especially noticeable in the game) are holding me back. Hopefully I’ll be getting a new PC or at least a new graphics card soon but for the time being I am trying to get the game to work as well as it can on my system as it’s my most played game.

        1. It looks like the developer changed the config file format. I’ll have to re-install ETS and have a look.

          When I originally made this article, I was using a GTX 970 and it did feel like it couldn’t keep up in places even with the tuning. I later upgraded to a GTX 1070 and tried it with ETS and it felt like ‘just enough’ hardware for a comfortable VR experience at that point.

          By all means, keep tuning your settings but it does seem that sometimes the best solution to VR performance issues is throwing hardware (money) at it! 🙂

          1. Yes I have tried all different combinations of config edits and SteamVR settings and in the end, I think my GPU just isn’t good enough for this game. In the end I have to turn asynchronous reprojection on in SteamVR, set the resolution to auto so it sets it dependent upon what my GPU can handle and keep independent timewarp and interleaved reprojection turned on in the ETS 2 config. The game looks rubbish because the resolution’s so low but it does handle a lot better, with a lot less stutter (but still some).

            As you said, I think really for VR you need to throw money at it and I think AMD cards aren’t particularly optimised for VR anyway. Hopefully soon enough I’ll have the funds available to buy a new GPU.
