a feature level 5 video card is required to run the editor

yet my windows 7 dual core with 16 gb ram and a gt 620 runs it fine i get long shader times yes but it works it will stall your pc for a while just go paint the living room , stack 60000 bricks or something till its done…then and ill say the pc next tome is only 2gb and is win ten and yet RUNS fine except it does 50% less shader workers and i cant fix that ive tried editing the files to add more or such it wont do it…
but now i have no lag its like the 6 core 6 thread pc it only sees 2 threads for shader workers some reason but they are as fast as 3 on older pc…
