the game launcher window (client window) creates bigger lags than e.g. badlion client. so it could be fixed, optimized.
because once you turn off the game launcher window in the background, it stops lagging
and generally forgetting about Lunar because it lags and it's strange and the game takes 3 minutes to start. In the case of, for example, Badlion client, it takes 15 seconds.
if something is unclear, please a ping me
