Key pressing slows down program execution?

[komame]

Tim,

I just downgraded the FW to 10077 and now the program works faster (230ms while not pressing a key and 285ms while pressing).

Regardless of how internal OS keyboard handlers were written, you can see that in FW 10077, the programs were executed faster.

I also wrote about it in this thread about my game two years ago after upgrading to FW 10637, when I noticed a significant decrease in performance compared to FW 10077.

In FW 10637 were problems with the flow of animation during the key pressing that did not occurs in version 10077.

I think that there is still the possibility of improving something and speeding up the execution of programs (even while the keys are not pressed) since in earlier FW they were executed faster.
