Terrible performance issues

I've been playing the game since the BETA, and noticed a few graphical glitches and low FPS. At the time, I didn't mind since the game was in a fairly early stage of development. But nowadays, it's unbearable.

With the new update, some of these issues have been fixed and smoothened out, but they still persist. It's incompetent of the devs to add new content, yet leave a lot of optimization by the side. You can't enjoy new content if you can barely run the game.

Some of the issues include, but aren't limited to:

Missing character, weapons and sounds in the beggining of a match.
Annoying stuttering when looking around corners/inside buildings (Probably rendering a new scene) which leads to some pretty bad CQC reactions
Missing reloading/throwing/firing/aiming animations

My setup:
Windows 7 64 bit
Intel Core i5 6400 @ 2.70GHz
4096MB Radeon RX 470

Hey there @Rockenbach

Thanks for reporting this. The devs are aware that some machines have had performance decreases, while others have improved. They are searching for solutions.

We understand this can be frustrating, so thank you for the patience. Have a great day!
