Last week my Oculus Rift software auto updated to a new version 12 release and straight away I found that all my games were unplayable due to frame dropping and stuttering problems and also motion tracking issues when on Oculus app version 220.127.116.11.268
I found a lot of other people with the same issue on reddit.com/r/oculus/ and it seems that the version 12 release can caused a lot of issues with Oculus CV1 first generation headset users.
Oculus don’t have any way to downgrade the software to the previous release but luckily on my brothers computer he didn’t have the "Automatic App Updates" option ticked and so his Oculus software was still on the previous 1.43 release which didn’t have the frame stuttering problems.
I would like to thank all the people who posted in https://www.reddit.com/r/oculus/comments/eahj7a/are_we_gonna_get_fix_for_the_stutter_issues_from/ who have tested this workaround.
This temporary fix will hopefully get your CV1 working again until Oculus fix the bugs with the latest version 12 software release.
To fix the stuttering issues on my computer I did the following:
In the oculus software go to Settings > General > and turn off Automatic App Updates.
This stops the software from automatically downloading and installing the new updates from Oculus. On my software the "Oculus software update" is showing as "Queued" in the Library > Updates tab.
Close the Oculus software.
Some users on Reddit also recommended amending the hosts file C:\Windows\System32\drivers\etc\hosts to add 127.0.0.1 securecdn.oculus.com to stop any further updates but I believe this also stops you downloading any new games or apps.
Using task manager kill the 3 Oculus process that are running.
Make a backup of the C:\Program Files\Oculus\Support\oculus-runtime folder and then remove the contents of this folder.
Download this file which contains the oculus-runtime folder and also the "oculus-drivers" folder from version 1.43 and extract to a folder on your computer.
Copy the files and folders in "oculus-runtime" into C:\Program Files\Oculus\Support\oculus-runtime
Restart your computer and try using your Oculus Rift CV1 which should have fixed the stuttering problems.
Possible Driver Error messages
A few users have reported that this doesn’t always work with an error about driver updates and so I have included the "oculus-drivers" folder in the archive which contains the oculus-driver.exe application which seems to fix this driver error.
Disclaimer: All the files have been copied direct from the Oculus software folder and have been virus checked but I don’t take any responsibility if your computer explodes, your house burns down or something nasty happens to your Rift headset!
