Does video/screen resolution affect browser performance?

Hello everyone,

As some of you may remember, I'm still on a very old system (non-SSE4.2+ CPU). I am close to upgrading my main monitor from 1080p to 1440p.

Does that come with a performance hit on Pale Moon? I am not talking about video/GPU intensive websites like YouTube etc. (my 1050 Ti should be good enough, hopefully) but rather the CPU/Javascript etc. intensive ones which do make Pale Moon CPU-hungry, and do not benefit all that much from the GPU.

I got some fairly conflicting info, ranging from "irrelevant, it's all on the GPU" to "a small but noticeable performance hit could be expected". Thanks.

It's a bit of both. The scripting happens on the CPU but the painting is on the GPU, so it really depends on how poorly written the site's code is.
""""""""Modern"""""""" frameworks tend to unnecessarily do CPU-bounded graphical operations for no reason whatsoever, so there are higher chances to see small slowdowns there if you really measure them with some dedicated tooling.
In terms of human perception it shouldn't be any more different than what you experience now.

And we aren't missing out on anything now, are we?

Maybe see if you can survive with Power Saver power plan or whatever to downclock your CPU.



I wonder if they ever had the problem back then that they had to wait for computer to catch up with the keyboard typing. That sure happens a lot today, despite all the gigahertz.

Youtube will serve VP9 instead of H264 for resolutions >1080p and this will definitely impact the performance, especially when there are problems with VP9 hardware video decoding.

Other than this... There should be no new problems, the biggest problem is Javascript, not screen resolution.
