WHenever I move the screen just feel very laggy and stutter a lot, I have a high end system and using win 10:

RTX 2080 Super (yes driver is updated)

i9 9900k

16gb ram

Tried using brave and haste potion but still get very laggy, it's not as smooth as those gameplay on youtube

Have tried compability mode on win 7 and win 8, still doesnt fix. Have tried both full screen and windowed mode, still doesn't help

I have tried using Leatrix Latency Fix but doesnt help much (yes I have restarted my pc several times)

I live in NA btw so I don't think ping is an issue here (US central)

I need help since I am unable to play with lag like this

I encounter the same issues. I thought that those fps drops are normal as it is old game, but then I looked at gameplays on youtube and I was disappointed. I cant enjoy the game because of those fps drops :/
