im using blender 2.78 and i have an amd Radeon 280x , by default when i go into user preferences in blender , blender wont detect open cl , so i tried out opening blender in the following way from command prompt:
set CYCLES_OPENCL_TEST=ALL
start blender.exe
this time open cl popped up on user preferences , but the graphics card that was listed was ‘tahiti’
so when i rendered using gpu afterward, there is no change in render times
am i doing somthing wrong?
ps:- blender 2.79 wont even recognizwe my gpu , even after the command prom[pt thingy
