My PC can handle most games well but the cpu is old so stuff like video editing is slow, i plan on upgrading it anyway though.

As of right now the game is very laggy and slow to respond to my cursor movements while others on the leader board are fine.

I tried playing it on my phone which works with no lag until i start recording

Here is a run i submitted which shows the lag: https://www.speedrun.com/couch_2048/run/yon9075z

How can i fix this?
