Visual artifacting and low fps

[MikeDfromCT]

What's up, everyone? I have a stock Galaxy s20+. Recently, I decided to experiment with different GPU drivers to get the most performance and fps out of the games I've tested as I could. The problem is, they cause visual artifacting. Particularly in DKC Returns. So I defaulted the GPU to default and kept the API at Vulkan. The driver I tried using was Turnip 23.3/Vulkan 1.3.261. My default system driver plays games well for the most part. But, back to DKC Returns, there are areas where the fps dips 10-20 fps out of the blue. I don't know if that can be attributed to the game itself not running well, the app itself, or the hardware. I also just recently picked up a Galaxy s23+ because it was time to upgrade to a more powerful and capable device to handle more demanding emulation. Using that is a mixed bag as well. So I'm at a crossroads on where to start tackling this issue. Any help would be greatly appreciated.
