Hi, I have an application that is using a SDL input thread to read an USB joystick. Would changing kernel frequency to 1000 Hz help for getting the least possible input latency? Or it has no effect at all in such a scenario? It is currently at 250 Hz.

Yes. Also consider ck-sources for additional smoothness patches.

Thanks. What about using my realtime kernel as general-purpose (Ingo M. rt patch)?
