Premiere Pro CC & Media Encoder GPU acceleration problem

after 2017 update, system (s.o. windows 10 home, i7-4710hq, nvidia gtx850m) take extremly longer amount of time render - same settings - before update. i thought problem gpu acceleration, if either in premiere pro project settings , in media encoder mercury gpu (cuda) mode selected. thought maybe problem with lastest video driver (375.95) made test rolling version until v.368.22, with no changes.

 

 

testing system gpu-z, have idea of gpu load during rendering, figured out gtx850m gpu not used @ , same occur @ cpu, integrated intel hd4600 maxed out, running 100% load time, , same occur if select software mercury engine mode.

 

any suggestion?

 

 

the gpusniffer report initialization failure (the same version of driver tested):
