my specs:
OS: Win 10 pro 64bit
CPU: Intel i5-6400 @ 2.7ghz
RAM: 8gb DDR4 @ 1066mhz
GPU: MSI GTX 1060 6gb
OS + game installed on 1x 240gb SSD

now that that's out of the way, since the last update on the 14th of September, the game is actually doing worse than it did before. the general FPS is lower, and consistently every once in a while the game freezes and studders horribly for about 5-10 seconds, and then goes back to normal.
FPS loss on smoke as well. especially when entering it.
something that was fixed before that patch has now reoccured but to a lesser degree than previously, when a player model enters my field of view i get an FPS drop.

and now, possibly one of the most bothersome things is the mouse issues i've have.
quick and snappy target acquisition is impossible, for when if i move the mouse too quickly, the camera will have either sporadic, glitchy, unresponsive movement, and i have to stop moving the mouse before it comes back to normal. that's the best i can describe, i hope it helps. i would really like to see a raw input option in the settings.
