Only when using fresco, my pen reacts slow - windows

I adjusted settings in and out of fresco, re-installed the app, updated pc 100s of times. I just can't find the bug to why only in the fresco app my pen reaction is slow. it takes away the 'realistic feel'. because if i draw a curved line, it only starts catching on later and ends up making a dot randomly. Or a straight line as if i was holding down the pen. I really don't want to use another application. PLEASE HELP :'( it was working before but for about two months now I've been looking for a solution. (Acer i7 travel Mate)
