As the title suggests. My new gpu was running choppy and after spending time I've narrowed it down to setting custom fan curve affecting performance.

I can set boosts, memory over clock, power target etc it all works fine as long as I don't touch fan curve.

As an example I leave everything as stock but just setting a custom fan curve then it seems to affect smoothness in gameplay. I'm using a game called genesis alpha one to test this and for 100% definite the fan curve is affecting smoothness. You can clearly see and feel dips but with fan curve off it's locked at 60.

I'm using latest adrenalin drivers has anyone else had this? I've troweled Google and many were complaining that they are getting these dips and stutters could it be possible a fan curve is messing the GPU up?
