Issue running on PC with decent specs

Any suggestions here are appreciated. I downloaded Genshin and experienced stuttering/frame drops straight away on the start menu.

I read articles and got it to the point where there was minimal stuttering (if any) on the start menu. Once I started the game it froze one minute in.

Games like Celeste, Hollow Knight, Spyro Reignited and others work fine but I don't think they're too demanding.

My specs are: Processor (CPU) Intel® Core™ i7 Eight Core Processor i7-9700K (3.6GHz) 12MB Cache Motherboard ASUS® PRIME Z390-P: ATX, LGA1151, USB 3.1, SATA 6GBs Memory (RAM) 32GB Corsair VENGEANCE DDR4 2400MHz (2 x 16GB) Graphics Card INTEGRATED GRAPHICS ACCELERATOR (GPU) (UHD Graphics 630) 1st Storage Drive 500GB Samsung 860 EVO 2.5" SSD, SATA 6Gb/s (upto 550MB/sR | 520MB/sW) 2nd Storage Drive 2TB SEAGATE BARRACUDA SATA-III 3.5" HDD, 6GB/s, 7200RPM, 256MB CACHE OS: Windows 10 Monitor: AOC Q3279VWFD8 2560x1440

If the issue is the graphics card does anyone have suggestions for an improvement? £150 max
