Movement is a lil off, any help?

[❤ TRose00 TTV❤]

I been playing binding of isaac afterbirth for a long time now. But one thing thats bothered me so much while playing the game is the movement while shooting.
Moving around is fine and i don't see any problems, its when i start shooting is when it becomes a problem.
when i move around with wasd and shoot with arrow keys, something happens.
If i try to use s and d at the same time only 1 of them works and the other acts like its not working unless i use that first. and no before you say its my keyboard, every keyboard i try'd did the same and yes it does the same with other pc's as well.
I'm currently on desktop windows 10 and i have played this game on a old version of windows, it does the same thing so my guess its just how the game works. But is there any idea how to fix it???
(note it sometimes does the same with A key if i used s and d key, forcing me to go bottom right even though Im not holding d while i hold down a and s) (And yes my gaming keyboards had the same problem, you were not here to witness it, no help if you keep telling me I'm lying)

Sorry but nothing else but the keyboard limitation comes to mind. I have played BoI on like 3 different keyboards and on win 7,8.1 and now 10 and nothing like this happened. it also works fine on a (4 years old I think?) old laptop.

Are you absolutely sure your keyboard does not have hardware limitation on simultaneous button presses?

Logitech keyboard, the ones you get when you first buy a pc. but this also apply'd to my other keyboards that were different, plus this does not happen on any other games for me besides this

It's your keyboard, most keyboards won't register more that 3/4 keys pressed at the same time. You euther get used to your inputs not registering or buy a gaming keyboard (check the specifications of the product first).

i forgot to specify i had gaming keyboards as well but they don't work anymore as they got water damaged, same applied to them.

It's still your keyboard...

No, your gaming keyboards didn't have this problem, like you are projecting hopefully.

Your keyboard(s) has a thing called "ghosting", basically you can't press more than a certain amount of keys at the same time otherwise the last inputs are not going to get registered. I recommend that you look for a mechanical keyboard or even a membrane one with anti-ghosting features.

You can try to rebind your keys so that you might me able to press 1 more of them before the ghosting happens, when I had a membrane keyboard with the same problem I set my shooting buttons to Num8, Num4, Num5 and Num6 (basically just moved the arrows to another place), I still play with these binds to this day because I got used to them.
