I appear to be getting a small stutter when pressing a key, for eg horn, reverser etc during the game. If I press the key again within 5 -10s or so there is no stutter. However, after this time if I press again I get the stutter. This also very occasionally happens with the xbox controller as well, when selecting throttle, brake etc. Other than this I get great performance, locking at 60fps. Only dips below at busy stations like Paddington. i7700k, Nvid 1080, 16gb RAM, ssd. Just wondering if this is a known thing or not. I'm guessing it's something my end, so will probably need to do some troubleshooting with my setup.
