This is also why picking a good monitor is important for software development. Some monitors have tons of input lag (60-70ms) and that's the time it takes for you to see what you're typing to reach the display. This also includes the time it takes to see you move your mouse cursor too.

I have the same monitor and it's pretty good. The only thing I don't quite like is the pixel size, it's a bit small for native scaling. I kind of wish i had gone for the 27". I went with two 25" because two 27" were a bit too big for me.
P2715Q user here. One of the best monitors currently available, excellent color reproduction, top of the line quality. The 4K resolution however is a major problem when you are using Windows 7. Some applications will not play correctly when you try to scale up and at the end you get a mess. Windows 10 is better, but not perfect.
The 4k resolution and scaling can cause issues with some apps as you noted. This is especially true if you use multiple panels with heterogeneous resolutions, connect with displayport and occasionally turn one monitor off. This causes windows to move everything to the other display which is a mess. However after futzing with it for a few days post-purchase I had it all working well enough to deal with, even though I occasionally get slack in an over-maxed window on the smaller display. Btw this program is really useful for smoothing mouse movement between the larger and smaller displays in windows 10: https://github.com/mgth/LittleBigMouse

Re: Desktop compositing latency is real
#144I turned off windows update quite a while ago and was considering updating my system recently until now.
I'm on version 1703
Build: 15063.138
Why would I ever update now?

I looked at 4k monitors but ultimately decided against it because as soon as you start scaling then you lose the extra screen real estate. At 4k 150% scaling you end up with the same screen space as 2560x1440.

Why do people care about affiliate links? Serious question.

ethernet over multimode fiber, I want to be able to have accessories hundreds of meters away from my computer
Careful, multi-mode fiber is near its scaling limits. 10GBASE-SR and 25GBASE-SR exist, but that's about it. (By contrast, 40GBASE-LR and 100GBASE-LR work over single-mode fiber, and DWDM + coherent optics can push the medium much further.) Wouldn't want to be stuck at 25 gbps forever ;-)

Layers of abstraction take you further away from the metal. The more layers of abstraction your keypress must traverse before rendering is complete and the photons have reached your retina, the longer it will be until that happens. Layers of abstraction make complex tasks more reachable by a larger number of programmers by reducing the amount of specialist knowledge about those lower layers required to do the job. Th…
Layers of abstraction make complex tasks more reachable by a larger number of programmers by reducing the amount of specialist knowledge about those lower layers required to do the job. The more layers of abstraction you have, the less they have to worry about lower levels and can just get on with what they want to do. Sometimes this is certainly true, but I think when it comes to abstraction layers, people tend to o…
Re: Desktop compositing latency is real
#150I recently measured it with my phone's camera in slow motion mode. The system is an AMD Ryzen 1800X with AMD R9 280x GPU, KDE Plasma with KWin window manager in compositing mode. Key press to screen output latency was ~33 millseconds (90 fps recording, so increments of 11) in KWrite. The computer feels plenty responsive with that latency, and I hate latency... It is a full stack real world result - for comparison pur…
How are you measuring from key activation?
