Since I installed it I noticed huge random keyboard lag when plaing some games (like NFS) while some other works fine (Quake 3 and games based on it’s engine).
Any way to fix it ???
I updated to 4.8.1178 but I still get the lag 
turning off the self-defence module in lates beta seems to fix the problem.
Hope the programmers take a look on it… self-defense module shouldn’t be due to keyboard lags…
