select 1.8.9 optifine lunar in launcher settings (make sure its not set to lunar x forge)
disable window title, nohitdelay and mouse raw accel mods
also to fix fps drops every 1-2 min, go to settings in solar launcher, scroll down and select "default" in jvm arguments (this is not vape issue, its solar issue you will still get fps drops even if you dont inject vape)
