I play tm2020 on PC with KB, and I've been having lots of issues with sticky and lagging inputs. I have occasions where my input will hold for an additional 0.5-2 seconds after I already let go of the input, while also having occasions where my input will not register until 0.5-2 seconds later. This applies to keys for car movement in addition to chatting and menu keys. This always happens after I've been playing the game for about 30min-1hour, and it is quite literally making the game unplayable for me. This kind of input issue is exclusive to tm2020 and does not happen in any other game I play.
I've seen people say some keyboards have a limited amount of keys you can press at once, though this is not the issue with my keyboard. My game is still running at a smooth 100fps in most cases, and the game itself does not seem to be lagging at all. Neither my CPU nor Memory are reaching close to 100% in task manager either. I've only seen 1 post on this topic anywhere and I was not able to find an answer from it. Does anyone have any idea how to resolve this issue?
