This on epic games, much better than the default download where it won't even open the world after the loading as I tested it yesterday but changed to epic games ver as I see some comments on Reddit that probability that some games will run smoother there
I dunno if this will last long to run here in the future updates but for now it's a mid smooth but still stutter sometimes while configuring some of it's settings to low and some to extreme low, while turning off the Anti-aliasing to retain sharpness of everything making it good to see in the eye and even the reflection is retained... doesn't have that much diff of you set it to high tho besides the details of stuffs, well since this on PC/laptop .... doesn't have much choice.haha, since my phone couldn't handle it anymore when my phone is nearly full maintaining Wuwa, genshin and in addition to Chaos Zero nightmare.
On very low potato laptop with HD graphics 620 btw and Intel core i5 7th gen.... laptop I only have and used at school

i hope the devs would work on the optimization because i think that was many players' problems yesterday. I'm glad its working a tad better on Epic for you, hoping for the best and enjoy!
