I wonder why the CMD starts and as soon sets

setx GPU_MAX_HEAP_SIZE 100
setx GPU_MAX_USE_SYNC_OBJECTS 1
setx GPU_SINGLE_ALLOC_PERCENT 100
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_MAX_SINGLE_ALLOC_PERCENT 100

------------------------------here it closes itself and makes a log file with the driver version, OS build

@echo off
cd %~dp0

cls
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"
set LOGTIME=%dt:~0,4%_%dt:~4,2%_%dt:~6,2%_%dt:~8,2%_%dt:~10,2%_%dt:~12,2%
set LOGTIME=%LOGTIME: =%
set LOGTIME=%LOGTIME:,=.%.txt


the v8 config looks like

{
"cryptonight_type" : "normalv8",
"intensity" : 0,
"double_threads" : true
"gpu_conf" :
[
   {
     "id" : 0,
     "intensity" : 122,
     "worksize" : 8,
     "threads" : 1
   },
   {
     "id" : 0,
     "intensity" : 124,
     "worksize" : 8,
     "threads" : 1
   },
   {
     "id" : 1,
     "intensity" : 122,
     "worksize" : 8,
     "threads" : 1
   },
   {
     "id" : 1,
     "intensity" : 124,
     "worksize" : 8,
     "threads" : 1
   }
]
}
