On the Pimax page, 8K recommended GPU is 1080Ti and 5K recommended GPU is 1070. Why the difference when they both effectively are 1440p?
8k need a bit higher supersampling
Yea what Industria said.
I believe that the 5K+ with the RGB type panel look good with the native resolution however the 8K with the crappy pentile style panels need more supersampling to get image more clear thus requiring more GPU.
It’s mainly like with games for reccommended base performance.
Depending on title even some folks have tested 980ti on games like skyrim with decent results. However for better overall min enjoyment a 1080ti is best.
