OP here - Doesn't run this particular software, and it's prohibitively expensive unless you've got corporate sponsorship. Would love to give it a try, though.
I haven't tried coding on Varjo, but I've played Alyx on their Varjo VR-1 headset. The resolution is incredible! No blur, no pixels visible. While playing, I often just stopped to look at things to see pixels or other flaws in them, but I couldn't really see any flaws. Also, texts looked very sharp like in the real world.
I think you mean Varjo. It's a pretty ridiculous headset, but the thing also forces you to buy a $2000/month subscription after you purchase it. It's safe to say it's not a really reasonable option.
It also doesn't actually have a particularly high resolution, and sort of cheats by making your periphery have a significantly lower resolution (hardware, not software, is responsible for this, so you can't just turn foveated rendering off), which makes it good for many use cases, but worse for programming.
Got a source for the "forces you to subscribe" bit? Everything I've seen says that part is optional.
Also, even disregarding the extra focal-spot screens, you're wrong about the resolution. It's the highest of all headsets that don't have insanely wide FOV's like the Pimax8K, by a long way.
2880 x 2720 per eye (Varjo VR-3) > 1832 x 1920 per eye (Quest 2) > 1440 x 1600 per eye (Vive Pro 2) ~= 1600 x 1440 per eye (Valve Index)
