gpu mining option not really working?
Hi ive been testing this builder for some time and its amazing!!!
but now ive been testing the gpu miner option but it doesnt seem to work? 
it startsup and i injected it in notepad so I watch the taskmanager to monitor it. after some time you will see the gpu percentage go up to around 35% and then immediatly it stops and doesnt use the gpu at all after that.
ive tried this with NVIDIA card and with AMD card and on the AMD is the only one that does this because NVIDIA doesnt even do that it just never uses the gpu at all.
stealth is turned off, cpu mining is off, installation is off,
ive tried multiple drivers for it older versions and newer versions, on the newest version it gives error that the driver got a timeout. on the older  versions it doesnt give you the error but it will only use the gpu for that one second.
am I doing something wrong?
any tips maybe?
