[Solved] MKAK (NPUB30468) Speed Issue

Hello!

First off, I am really amazed by the progress RPCS3 and the Team behind it has made throughout the last years. Really amazing!

I have a strange issue with Mortal Kombat: Arcade Kollection (NPUB30468). The game runs at approximately 40-50fps and it just won't increase. 

Funny thing is, that I've made this video 3 years ago on a PC of a friend of mine - much slower than my current one and much earlier RPCS3 version:

Can someone please provide any tips how to improve the fps?

My PC specs:
Intel® Core™ i7-9700K Coffee Lake (12M Cache, up to 4.90 GHz, LGA1151)
GIGABYTE GeForce RTX 2070 SUPER Gaming OC 3X 8GB GDDR6
Kingston HyperX Predator 32GB(2x16GB) DDR4 3000MHz CL15 HX430C15PB3K2/16

Attached is my config file. I also have some strange log errors (which I am not sure if affect somehow on the emulation) like:
p, li { white-space: pre-wrap; }
