Reaction to pressing Shift is delayed, even with "Optimize for games"

I'm running Windows 7 and tried to play some precision platforming games, e.g. http://www.delicious-fruit.com/ratings/game_details.php?id=12373
These games require precise inputs and reaction time on key press >10-20ms can make a difference. The default "jump" key for many of these games is Shift. Even with "Optimize for games" enabled, there is still delay 50-100ms. Without "Optimize for games" it's even worse, aka 300-400ms. When I re-bind the "jump" key in the example game to "z", it works with no delay. However, not all of similar games allow key re-binding, forcing to use Shift for jumps. Can you make reaction time on Shift key as fast as on other key like "z", please? While playing those games, I can even be ok with non-smooth work of combinations Shift+key.
 
Hi,
Could you try to paste following bootflag in VM configuration Hardware > Boot Order > Advanced > Boot flags:
devices.kbd.end_delay=10
also you may try this one:
devices.kbd.end_delay=0
 
Thanks a lot!
This solved the issue. I can't clearly tell the difference with using Shift or not Shift with value 10. I'll use 0 though just to guarantee no delay.
 
Hello Friends
These diversions require exact inputs and response time on key press 10-20ms can have any kind of effect. The default "hop" key for a number of these amusements is Shift.
