OK, it isn't strictly Eastern Front but it is still affecting it, and I figured that we have a pretty good knowledge pool here.
I am using my dad's new Vista Quadcore to run all my games, but every single one of them suffers from a certain keystroke lag.
No matter what settings I run them on, the same problem persists; it takes a few tries before keystrokes are recognised, and if you hold them down at all, the game assumes it is still being pressed for some time after I let go (it appears the longer I hold, the longer it lags afterwards).
The same problem does not exist with other software. Internet Explorer works as it should, so does notepad.
I can play RTS's fine, because the mouse doesn't lag in the slightest, but it makes action games nigh unplayable.
I have tried running games in low and high priority, I have tried running them windowed and I have tried a different keyboard. I have even closed down a variety of background processes, but no luck.
Any ideas?
