I don’t think you’re GPU bound, it’s probably CPU bound. Minecraft isn’t necessarily designed to be hyper performant when it comes to gameplay because it didn’t need to be. It isn’t a competitive platform and fps doesn’t usually matter too much because it’s just Minecraft. Mod textures and shaders loading could also have an impact

With that being said, although the CPU has a pretty solid single thread rating, the “gaming score” as per CPU benchmark puts it at a relatively weak number with consideration for the single thread rating, most likely due to a low L2/L3 cache. Try to open up some hardware monitoring software to see how it’s doing when you hit the bottlenecks

Haven’t looked into it, but always turn off or disconnect devices with an active infection. Troubleshoot as much as possible from a different system to build up a plan.

If you’re connected to data, just assume someone has a method of tracking you and that someone else might be interested in purchasing that data

Might be an issue on their end, have you tried giving them a call?

Maybe DNS issues, have you tried trouble shooting from the command line?

It’d probably be a lot easier to change it on your laptop instead of on your phone.

I’d use the solution that doesn’t require downloading that third party software 🤙
