Hi,
I understand that probably for most of you guys this isn't an issue at all, and noone cares about it but well.. I do I remember when the sa-mp competetive scene was in it's top form back in like 2010 I tried to convince a lot of people to switch to mta because sa-mp scripting is a joke, but they didn't want to. They kept saying mta felt "weird". Now, 10 years later I know exactly what the problem is.
* Important notice: It doesn't seem like it's an fps-related issue, since the lock occurs and is the same in 1-70fps range with around 72 and above making you unable to move
* sa-mp is what the orignal game is like
