Hi guys, noob here. Using a RPI 4 4gb ram with running raspbian book worm. running a usb touchscreen with react CarPlay. Just got it installed with the script and it’s working but rather laggy in the CarPlay screen. Is there any adjustment for this? the FPS is set a 20fps and DPI is 60. I was using open auto pro with this screen and no lag before so I know the hardware should be good. Let me know what to check/post.
Just checked, The screen buffer is on. If someone has any tips please let me know! really want to get this up and running in my car.
Have you tried increasing the fps from the default 20 to 60? It does feel much smoother, a pi should have no issues running it at 60 on the official screen. What resolution are you running at?
I am running a Chinese HDMI touchscreen. I included a picture of the settings on the reactcarplay. I set gpu men on the pi to 512. Still same story. I’ll upload a video of the performance.
The display is 5.5" AMOLED 1920x1080 HDMI touchscreen panel. Worked great on open auto.
Here is a link to a video showing the lag.
Yeah the resolution of the display is just too high for the pi unfortunately, open auto was a completely different bit of software so was performant at playing the video feed

Thanks for the tip. I lowered the resolution to 800x600 and increased the gpu mem to 1024. Getting much more usable performance on the same screen now. Still not a buttery as open auto but I will take it
