Maybe you have been running MTA since a long time or for hours and your pc has low specs. If yes then its normal to face such things, its good some times to restart MTA the lag will reduce , its like refreshing it many problems get fixed by that
Greetings,I was online few hours again and I faced the same problem while my internet is stable. I think that server was lagging a bit in that period, or it might be the problem with your isp. Is there anyone using the internet while you play? If the delay isn't fixed yet, I recommand you to Close any background websites and programs and to connect your device to Your router via an Ethernet Cable.If there problem is related to server, It will be fixed as soon as a developer notice that lag.
