Have you tried either the Vive or CV1 Oculus? Both are quite immersive, sure pixels are larger like some 2000 era graphics. But back then I was immersed just like now. Devs tend to be overly picky about things they didn't used to be just because say on mobile or monitors you have higher. The immersion trade off of full wrap around head tracking compared to high res in a rectangle is worth it.
