Latest patch that came out was probably the best one for me yet. Specifically because of the highlighted part of the patch notes. I can now play at 4K over 60FPS.
 
 
Client optimization

• Optimized game performance for 6-core or higher CPU
• Optimized UI

Sound effects

• Decreased motorbike engine and vehicle skid sound volumes

Bug fixes

• Improved character animation when using throwables while prone
• Fixed a bug that occasionally disabled voice chat on the Starting Island
• Fixed a bug that caused your character to stand before crouching when revived
• Fixed a bug that prevented players from rebinding Unarm to an alternate key
• You can now see the mark from the character you are spectating on both the Mini Map and World Map
• Fixed a visual bug with the scope while a character you are spectating is prone on a hill
• Fixed a bug caused by changing “Graphics” – “Quality” – “Effects” from Settings
• Improved the wrist positions on the steering wheel

For some reason I still couldn't hear anyone on the starting island yesterday after the patch. I'll check again when I get home from work today.

step 1: install PUBG
step 2: disable voice chat
step 3: enjoy
 
I am interested to try this out on my 3930k to see if there are any improvements.

With $1600 worth of GPU in your computer it better run at 4k at a decent framerate.

This was the only one that I was having issues with, due to it being early access. But they keep releasing updates like this and it keeps improving so I won't complain. I need to re-install Ark: Survival to see how much performance improved since I last played on my previous build.

400 Hours , hooked to this game lol !

I love playing it with my friends. I don't like to play solo, maybe once in awhile.

I'm kinda the same here, but my friends are rarely on so solo it is.
