HDR palette causeing extreme Lag V17.2

HDR palette not working good in 17.2 Anyone having issues with V17.2? V171.1. was totally fine, even the HDR palette, everything was perfect.
But now my colour page is extremely laggy. (specs below) and I feel it's as soon as I use the HDR palette.
So I opened up the 'Geforce Experience app & it told me that Davinci wasn't optimized for my GPU. So I clicked optimize and fixed it immediately! .... OR SO I THOUGHT!!!
what I realised is that it starts lagging from a few minutes of use onwards, so I was fooled. Like the GPU is getting full or something. HDR palette not working good in 17.2 (for some)
