It's not the drawing an icon to a screen that takes the half second, it's querying out to hardware on driver stacks designed for PCI WiFi adapters from the XP era along with all the other driver statuses.
It's like how Wi-Fi drivers would cause lag from querying their status, lots of poorly designed drivers and archaic frameworks for them to plug in.
And I doubt any hardware you had when Wolfenstein:ET came out rendered the game that fast. I remember it running at less than 60fps back in '03 on my computer. So slow, poorly optimized, I get better frame rates in Half Life. Why would anyone write something so buggy, unoptimized, and slow?!
You don't need to query the hardware to know the network interface is up. A higher level of the stack already knows that along with info like addresses, routes, DNS servers, etc.
IIRC it ran at 76 fps (higher than monitor refresh, one of the locally optimal frame rates for move speed/trick jumps) for me back then on something like an GeForce FX 5200? As long as you had a dedicated GPU it could hit 60 just fine. I think it could even hit 43 (another optimal rate) on an iGPU, which were terrible back then.
In any case, modern software can't even hit monitor refresh latency on modern hardware. That's the issue.
It's not just showing "is the interface up", it's showing current signal strength, showing current ssid, showing results from the recent poll of stations, etc.
And then doing the same for Bluetooth.
And then doing the same for screen rotation and rotation lock settings. And sound settings, And then another set of settings. And another set of settings. All from different places of the system configuration while still having the backwards compatibility of all those old systems.
It's not a slowness on painting it. It can do that at screen refresh rates no problem. It's a question of querying all these old systems which often result in actual driver queries to get the information.
43fps? Sure sounds slow to me. Why not 333fps on that hardware? So bloated, so slow.
You're just listing mechanisms for how it might be slow, but that doesn't really make it sensible. Why would the OS query hardware for something like screen rotation or volume? It knows these things. They don't randomly change. It also knows the SSID it's connected to and the results of the last poll (which it continuously does to see if it should move).
And yes it should cache that info. We're talking bytes. Less than 0.0001% of the available memory.
Things were different on old hardware because old hardware was over 1000x slower. On modern hardware, you should expect everything to be instantaneous.
