I get following error in the command line prompt when starting Logic 2:
[58131:0916/113315.674419:ERROR:media/gpu/vaapi/vaapi_wrapper.cc:1662] Installed VAAPI version is too old. min supported version: 1.17 installed version: 1.14
Logic 2 seems to work fine but what does the error mean? Can I ignore it?
I’m using Logic-2.4.46-linux-x64.AppImage. I did not get this error message with Logic-2.4.40-linux-x64.AppImage.
Hello!
That error is coming from Chromium, which we use to render our software’s GUI. (our application is Electron based, similar to other apps like VS code, slack, discord, and more.)
If the software runs fine, despite that error, you might be OK, however I suspect that it might mean the software has fallen back to software rendering. We don’t have a quick way to directly check, but there is a simple test you can do. Try recording some analog data (we render analog data using webGL) and full screen the application, and max out the channel height so it fills the screen.
Then, pan and zoom on both axis. If the frame rate is pretty good, then it’s definitely using 3d acceleration.
If you’re getting a terrible frame rate (e.g. 1fps when full screen on a 4K display) then you’re certainly using software rendering, and we should try to fix it. Let us know if that’s the case.
You can force software rendering by launching our software with the --disable-gpu option to see the difference, in case you’re not sure. There should be a huge performance difference between software and hardware rendering.
The hallmark of Software acceleration is the smaller you make the software window, the smoother it runs. Also it’s the analog channels that are doing most of the work, so software rendering performance also depends on how much screen space those are using.
Simulation device & data is fine for this test, you don’t need to have a device connected.
