lag

its been many hours now that i get lag spikes. i play on heredur. i tried everything that could cause this lag when it comes to my pc. so i dont think its my pc that has problem. and its curious cause noone here said nothing about that lag. so i wanna get an answer if this is a server issue or some problem on my pc that i dont know.

 

While lag is sometime server side, it is more often client side (especially if it is just you and not everyone at the same time). I'd start by looking at the troubleshooting guide and trying all the steps listed there (Troubleshooting guide can be found in my signature below).
If the problem persists, consider the following:
If you have anything that runs an upload in the background, that will make you lag. Even a phone connected to the same network can cause this. Check if your router has IP monitoring tools and let those run in the background and see what happens to your network traffic while you experience these mysterious lag spikes.
