Refresh rate

Post by 4773n0x »

From my experience , raspberry pi zero and raspberry pi 3 b+ can't handle default refresh rate 10. Because of this, I have to use command line every time with "-r 20". It would be nice if @Matlo could add a refresh rate option to the main gimx-launcher. It shouldn't be difficult. I hope this gets added in the next gimx update. Thank you. It's the only thing stopping me from using gimx-launcher.

IMO default refresh rate is good enough :)

For me, refresh rate 10 makes it very stuttery.

This is very likely due to a low mouse polling rate. Try adding usbhid.mousepoll=4 to cmdline.txt.

I can't. I use a simple office mouse. Max refresh rate for this mouse is 125hz. But I don't think it's the refresh rate. On a Windows laptop, refresh rate 10 worked fine, but not on raspberry pi zero or raspberry pi 3 b+.

Did you try? The hardware may support it. If it does not work, also try usbhid.mousepoll=8.

Some firmwares (like EMUG29PS4) run on RPi with a refresh period of 5ms without any issue.
