Graphics aggro with Nvidia App

Hi Guys
for weeks now ive been struggling with Nvidia app , "optimising "my game
I was running high quality but jerky screen …not good or god smooth fps 200 + but tosh quality …
every day my adjustments were gone auto optimised away …
so I removed Nvidia app all ok set WT on Max great good qual 200 fps …
just thought id reload Nvidia app to get new driver but I didn’t press optimise … all is still good so don’t be tempted to press optimse or it will all go to sh**
thanks if this helps any one great .
