@GH0ST0326 You’re welcome! I have the same issues with apex a few years back and it turns out the intel cpu in my MacBook is constantly going to sleep state, causing massive stuttering. After using a tool called “cpu unpark”, the problem resolved. However I don’t think apex would still have such issues with windows power management nowadays, but you can still give it a try. You should also see if updating or manually installing your chipset drivers makes a difference (go to your motherboard’s manufacturer’s website for that) and also disable all gsync or free sync compatible features in your driver. Another thing I can think of is to turn off lighting sync in apex settings. That is a feature that the game changes your devices RGB lighting based on something happening in game if you have a compatible device and with the correct drivers installed, but many people seem to have issues with it.
If you are using TeamSpeak with overwolf or discord, try turning everything related to ingame overlay off. Including the windows gaming one that many people uses custom crosshair with, that sometimes can cause significant performance issues from my testing.
