NVIDIA RTX Voice Can Run On Non-RTX GPUs

NVIDIA released its AI-based noise cancellation software last week for the RTX GPUs as they apparently need the Tensor cores to function properly. A forum user on Guru3D has recently discovered a manual workaround to get this application running on non-RTX GPUs, including Windows 7.

The workaround is fairly simple and it appears to just be soft-blocked by a line of code, which indicates the software can run with CUDA cores as well, albeit with possible performance impacts. Regardless, if you’d like to try it out for yourself, here’s what you need to do.

  • Run the RTX Voice installer normally until you encounter an error message telling you the application isn’t supported on your graphics card.
  • At this point, the installer has already unpacked all the necessary files into a temporary folder called “NVRTXVoice” into your C Drive, at “C:\temp\NVRTXVoice”.
  • Once you navigate to that folder, find “RTXVoice.nvi” inside the “NvAFX” folder (C:\temp\NVRTXVoice\NvAFX\RTXVoice.nvi) and open it with any text editor using administrator privileges. Once you’re in there, remove the “constraints” section which is the following –
<property name="Feature.RTXVoice" level="silent" text="${{InstallBlockedMessage}}"/>
  • Just save the file (if it refuses, save it into another location and then copy and paste the edited file onto the older one). Now you’re good to go, navigate back to the “NVRTXVoice” folder and run setup.exe (C:\temp\NVRTXVoice\setup.exe). Make sure the other installer is closed at this point.

We were able to get it running on a GeForce GTX 1080Ti on our end and the results were great, with just 1% of GPU load and around 700 MB on the RAM. The Guru3D user has been able to get it running on the GTX 1080 and Titan V. The other users have reported similar findings suggesting it works on all GeForce GTX 10 and 16 series cards. The 900 series seems to have mixed results though.

At this point, we’re not sure if there could be other noticeable impacts by using a non-RTX GPU or if this was really a marketing strategy, but it doesn’t hurt to try as it’s free if you’ve got an NVIDIA GPU and the noise-cancellation results are great. It remains to be seen if RTX Voice has any performance impact on the CUDA GeForce graphics cards that lack Tensor cores.

NVIDIA will likely patch this out soon, so if you’re interested in getting it running, we recommend you keep a copy of the current version’s installer, the Beta-Ver., which you can get here.
