Question about changing from HD to QHD mo nitor

I’m using a NVIDIA GeForce RTX 3060

With my current HD (1080p) monitor, i’m geting around 85-110 FPS

Just wondering how much FPS i’ll get if i switch to a 1440p monitor?

and how much fps do i need to run solo shuffle arena smoothly without delay?

In this scenario, your GPU requirements will increase, but your CPU requirements will basically stay the same. So by far the most helpful information you can gather is to determine if your GPU is currently a bottleneck or not.

Mainly, what you are looking for, is to see if your GPU is already pegged at 100% usage while you are playing. Even “Task Manager” can show you this information now on modern versions of Windows. If you have a 2nd monitor, keeping Task Manager up on your 2nd monitor while you game is ideal, otherwise you can alt-tab back and forth to see what the history graph in Task Manager shows for your GPU usage.

GPU pegged at 100% usage = GPU bottleneck. You will see a FPS decrease by moving to a higher-resolution monitor.

GPU not pegged at 100% usage = CPU (or other) bottleneck, extra GPU resources available. You may see the exact same or only slightly reduced FPS when moving to a higher resolution monitor.

You really need to test this yourself, as relying on reviews and things like youtube videos are going to give you information that is either useless, or vaguely useful at best if they actually test WoW (hardly any do these days).

Specifically in WoW you can emulate this already. Increase your Render Scale to 133% and you’ll effectively be running in 1440p. That way there’s no guessing involved - the actual impact of changing screen will be near enough identical (unless you forget to change it back to 100% after changing it).

It’s otherwise impossible to give an accurate estimate. You’re going to be rendering nearly twice the pixels, but without knowing exactly how much load your shader cores or ROP units are under this could have a correspondingly negative impact or it could have none at all. I do know that at points in WoW’s history it has had a near linear relationship between resolution and performance, but haven’t done any meaningful testing on the subject since Legion - and if you add ray-tracing on top that could easily shift things again.
