That's up to AMD I guess. They've only implemented support for variable rate shading for DX12. You can use fsr with OC and OpenXR toolkit, but there are some restrictions: OpenComposite OpenXR

 

Unfortunately there are no real benefits from using opencomposite for AMD at the moment. FFR really is the killer feature.

I'm back to openfsr 1.1, which has the menu working making it more convenient.

It's a bummer, but it is what it is.

I seem to have some difficulty with maintaing 90fps, which is impossible on some tracks like SPA / nurburgring. There are sections where it dips. Hockenheim ring and Jerez for example work flawlessly 90fps.

Luckily I have automatic motion reprojection working quite well. You hardly notice when it kicks in nowadays I really have to look sideways at other cars or objects on the side to see the shimmer/judder realising that motion reprojection is on, which is nice.

Despite these inconveniences, I'm still in love with this game. With my new simrig (Simlab Evo GT1) and Simagic alpha mini it's absolutely amazing and such a joy to race!

 

Any chance someone could do a step by step instruction video on how to set up Automobilista 2 with the Opencomposite and Open XR Toolkit? I cant seem to follow all the steps in the written format

 

Any AMD users here?

I noticed that with the last driver 22.5.2 shadows are often "crushed" meaning you will have completely black textures when things are in the shadow.

I used to have flickering also, but this was fixed after a re-install

 

I use only the dll so each game have to be set up individually. Have a WMR headset (Hp Reverb)
Download and install OpenXR Toolkit
Quickstart

Open this web page.
Files · openxr · Campbell Suter (ZNix) / OpenComposite · GitLab
Scroll down a little and download the 64bit dll of Openvr_api.dll

Open the folder: steam\steamapps\commonAutomobilista 2\x64
Rename the openvr_api.dll to something else like openvr_api.org?
Copy the newly downloaded openvr_api.dll into that x64 folder.
in same x64 folder make a text file named opencomposite.ini
copy this text into it.

admitUnknownProps=enabled

Save file make sure it doesn't get saved as .txt but as .ini

Run OpenXR Toolkit.
Start Ams 2 in SteamVR
It will now not start SteamVR but use OpenXR and should start faster and have better colors and feel more smooth.
Use Crtl+F2 to open the Menu for OpenXR toolkit.
Little hard to navigate before you get used to it as after 10 sec without key input is closes down the Menu again.
For now the FSR and NIS upscaler prevents the Menu from showing in VR headset so I do not use that setting but you can change game resolution or use FFR to reduce GPU load.

For me the mouse doesn't work until I have been on track once but then the mouse works fine in the game menu.

 

I have a 6900xt and had terrible problems with the latest AMD drivers. Block shadows, blacked out gauges and all around poor performance. I went back to the 22.5.1 drivers and it seems to have sorted out most problems.

 

I tried everything you wrote but when i start Automobilista 2 in Steam VR i get the message "could not start the game" "The program is already running"
Also have a Reverb G2 and a 3080ti. Im running with motion reprojection on. (Perhaps this is the problem?)

Update!!
After rebooting my computer i now get the message "unknown string property - dev; 0, prop: 1006" when i try to start the game from SteamVR.

 

What do you mean when you say start the game 'from SteamVR'? You should be starting it from the Steam desktop client, selecting 'SteamVR mode'. If you try and launch from your headset within SteamVR, it's never going to work - the tool is there to bypass SteamVR, not use it.

If you've solved that problem, and are now just getting the unknown property error, then you haven't set up the opencomposite.ini file properly. Incorrect spelling or it's in the wrong place. In particular, make sure your file is called opencomposite.ini and not opencomposite.ini.txt

The openovr_log file should tell you where it's looking for the file and if it's found it. The log file will usually be in your steamapps/common/Automobilista 2 folder. If it isn't, look in the x64 folder.

 

I got that error as I hadn’t started the WMR portal first. SteamVR will start WMR if not already running, but after this mod and using OpenXR you have to do it yourself first

 

Hey guys, new to ams2 and VR. I'm up and running, but pretty lost in everything VR settings wise. Have a 3080 , 12600k, 32gb ram and a rift s. Can anyone suggest some settings to make it look even better?

 

I started my game from the Steam desktop client selecting "SteamVR mode". Also i made sure that my WMR portal was running first but it still gives my the "unknown string property - dev; 0, prop: 1006" and my headset goes black.

Im not sure what you meant about the "openovr_log" file. Its located in the Automobilista 2 folder and its only 4kb. Not able to open it.
The opencomposite.ini file is located in my x64 folder and i made sure it has saved with the ini at the end. Also i copy pasted your textcommand "admitUnknownProps=enabled".
I really appreciate your effort of trying to help me but it feels like im stuck.

 

I tried this and still i get the same message unfortunatly.

 

I can cope what is written in the openovr_log file here and perhaps someone can tell me whats wrong or if something is missing cuz this is pretty much like chinese to me lol

"No config file found at C:\Program Files (x86)\Steam\steamapps\common\Automobilista 2\opencomposite.ini"
Looks like you got the .ini file wrong? I struggled a bit with this myself, but got it working by doing this:
Open notepad.
Copy/paste this: admitUnknownProps=enabled
Click File-->Save As..
File name: opencomposite.ini
Save as type: All files

 

Try placing the ini file straight in the AMS2 folder instead of x64

 

I picked up a Reverb G2. Got it looking really good while locked at 90 fps for sunny/dry conditions. Still sorting out settings for night/rain.

 

nvm.. I see Mikael's question was already answered by Sims Alabim

 

I use motion smoothing auto when getting rain/night otherwise resolution has to be set very low.

 

Just as smal update.
I got the opencomposite and the openXRtoolkit working.
I messed around with alot of settings like Fixed FR, NIS motion reprojection.
Was not happy with the results even after 2 hours tinkering (After like 45 restarts lol).
Suddenly i managed to get 90fps without Motion reprojection almost a whole race with a resolution of 3160*3100 with no upscaling just FFR at quality - wide.
Looks amazingly crisp and fluid (Im used to motion reprojection and a whobbly picture)
OFC when the rain starts i get drops to 82 fps.
Im really happy with my somehow magic settings and i hope to get the same performance the next time i start up the sim
HP Reverb G2 and 3080ti
