Davinci Resolve Lags in RTX 4050

So I recently bought a new laptop with 13th gen intel i7. 16 gigs ram and rtx 4050, but davinci resolve lags very hard even in these specs. So before this i was using my old laptop which had like 8gigs of ram and 1650 and even that ran just as good as i am able to run it on my current laptop which is so frustrating.

What really lags is the playback, even after setting the playback to quarter it lags hard, and just so you guys know, i am editing like 720/1080p resolution 20 seconds videos. Somebody please help. at the time of installing, davinci resolve clearly stated its using my rtx 4050 cuda cuda something i am not sure, but its deffo using the graphics card but it still lags.

Any help is super appreciated, thanks!
