Alright, so, I basically struggle to play this new version a lot, it lags sooo much. I barely managed to pass the introduction, get to Gearen, and it does not get better. I don't know why this happens, but it makes me sad bc I really wanted to play v13 the best way possible.
Before v13, I used this MKXP port for v12 that someone maked: This one. In this one, I could run everywhere and face no lag, and even use the speed up function. My laptop is not really good, but if it managed to play v12 smoothly, idk why it could not do it on v13.
Edit (07/21): I just copied the files about mkxp from the v12 that I provided and replaced the ones in v13. It's somehow working, running in 30-25 fps. I'm surprised, lol
