Substantial FPS drops after 4.01 (PC)

Hello, first time posting here.

After the patch yesterday, I have been constantly experiencing frame drops from around 70-80 FPS to 20-30 FPS.

By constantly, FPS drops occurs every 5 seconds and then goes back up again. I've tried simulating this in various maps such as Housing maps (i.e., Mist) with no other players in the vicinity; Idyllshire and Rhalgr's Reach.

Said FPS drops occurs in all 3 instances. I'm checking the FPS via the "System Configuration". It gets way worse during hunts/big FATEs since the drops becomes from 40-50 FPS to 8-15 FPS.

As mentioned, this has never occurred prior to Patch 4.01. Current System Settings has been toggled to Standard (Laptop). Even tried configuring various options to OFF, or LOW.

I also tried using both DX11 and DX9 if it is the issue, but it is still the same.

I hope someone can help on this. Thank you in advance!

Hardware are:

Intel Core i7-4710HQ @ 2.50GHz (8 CPUs)
Nvidia GeForce GTX 870M
16GB RAM

I'm having the same issue. Went from easily 150-200+ FPS w/ maximum settings 4k Borderless Fullscreen, to 40FPS minimum settings 1920x1080. Only change has been the new patch.

I have also noticed that my CPU usage went from sub 10% (spiking to about 12%-18% for brief moments, but never sitting at 15%+) to constant 22%-23% with long moments of 34%+. My memory usage also went from constantly 900mb-990mb (Never over 1,000mb) to starting at 1,098mb and slowly increasing to 1,700mb+ (Closed game out instead of allowing it to constantly attack my CPU's temperature.)

To me, the fact that the memory usage is constantly rising, no matter what zone I'm in or where I'm at kind of hints at a memory leak. However, even if it's not the drop in my FPS to be unable to hold 60fps at minimum settings is a clear indicator something is wrong. I already tried to tweak my Nvidia and Windows 10 settings, as well as some other "fixes" with similar issues others had in the past. However, nothing has helped.
