Let's assume; VR is much better than alt-tab and clicking at the taskbar. It will reduce the time taken by 95%. Assume 5 seconds average for non-VR method, which is a conservative estimate, this gives us 0.15 seconds for VR.

If you switch windows every 60 seconds, this gives us an improvement of ~8%.

Table:

300s -> 1.5%

120s -> 4%

60s -> 8%

30s -> 16%

15s -> 32%

I have no idea what my average window switch time is. I should measure it sometime. I doubt it is under 30 seconds where the VR actually makes a meaningful improvement.

If you take an average of 2 seconds for non-VR and a skilled user with keyboard shortcuts and virtual desktops, VR advantage becomes insignificant.

Table:

300s -> 0.6%

120s -> 1.5%

60s -> 3%

30s -> 6%

15s -> 12%

If you compare a specialized window managing software versus the VR equivalent then I don't see any benefit towards the latter. The latency is the same. The only difference is the abstract windows management versus spacial of VR.

I think programmers can handle the non-VR solution just fine. I really hope it becomes better though; the resolution is currently just too small.
