Your absolutely correct. Thats also why i said i understand with the major restructuring they did in 1.2.x it would need exploring & those whom are adamant about the preferance would need to be patient.
Closed/Proprietary projects have limited resources to work on projects.
Now i will admit it is worthwhile to put it on the list. One gentleman bought the Pimax specifically to replace something like a 6 display desktop & needs the fidelity/performance that the steam render provides.
& for folks like myself that like to challenge older hardware (2x7950 cf). Unfortunately the steam render plays better. The benefit of course with this that while only vr capable(med settings) the Pimax does so with finess. Allowing in the forums here
This is the minimum spec gpu; however several users have tested the following GPUs will work with reduced setting.
Like you said though its diving out the resources & prioritizing & with the big leap version roll out to 2.0 their plate is likely to be quite full.
All the complaints on res/performance might even be more or less resolved in the All In One driver.
