i got a new gpu gigabyte RX 580 8gig of ram memory the opencl is elmsmere and thought i would try opencl. my last card had 4gb and could handle one character with 2 subdivision with hair and props ect.

This new one will render ok with a prop ot two but even a base g8 cuases luxrender to go off the chart in memory up 12 gig leaving the gpu waiting forever for some data.

so in breif a 2 gig seen goes to luxrender is has increased to a very large amount of memory higher then the card. it just seems a bit odd that my 4 gig cards would be okay with the same scene
its not the end of the world if it doesnt work the gpu was for playing games mainly as i use the cpu for luxrender but it would be nice to work
is this a known issue?

ignore this

i got a single figure working fine and the gpu is useing the same size data as on daz. luxrender some still boosted up to huge amounts and then it was fine
