Yeah, me too was wondering if there are ways to avoid lag or other things. I noticed even alone testing in these first minutes I came back that there is some lag.
Anyway this can be contextual to the non activity of server. Or maybe some settings I changed?
My pc is capable to handle high settings and actually good pc do not work well with low settings.
I believe it's not a matter of high graphics here, right?
The internet is what it is around 15Mbps and 1 in upload.
It's important to distinguish between lag/latency and performance issues.
It's a lag/latency issue if your inputs take a while to reach the server. Usually this will mean that everything looks smooth on the screen, but you're unable to make jumps or hit targets because your packets arrive too late.
If it's a performance issue, you may see stuttering (i.e stuck on the same frame for too long) or something like that. It's nothing to do with the latency to the server, but rather the performance of the local machine.
With that said, your situation sounds like the latter. I'm sure you have a powerful machine. And in fact, for years now, PCs that are too powerful have been the issue. I don't know the exact details as to why. But they end up trying to push out more and more frames, and then at some point something breaks. And as a result you have a worse experience than you would on a lower specced PC.
My understanding is that (if this is the issue) you normally want to cap the max FPS to something reasonable. Maybe this will be of help:
https://aao25.com/forum/support/fps-locked-at-85fps/I think I've also read / heard of people setting their max FPS through the graphics drivers. Perhaps that was in the discord since I wasn't able to find it here. I don't know for sure since I don't have that issue - I run on a 7 year old laptop (whenever I do play).
