For my system specs:
Intel i7-6700k @ 4.0ghz
EVGA GTX 970
Running the game from an SSD, the the OS on a separate SSD
16GB RAM (because I kept getting RAM issues with 8gb)
My framerate stays around 60 capped by CPU ever since I upgraded my computer. Well, actually, the only thing I kept were the hard drives, the GPU, and the case, but still. It will dip below 60 during large battles or when there's tons of crap on the screen. I've noticed a very strange phenomenon where sometimes when the FPS drops it goes to just the right 'speed' where if I'm controlling recoil correctly then the screen doesn't even appear to move. It's pretty rare though. As for my settings, various things are either turns all the way to maximum or turned off completely. I used
this little guide to help tweak my settings. Also, pro tip, if you want motion blur (because your framerate sucks) set the 'overall quality' to ULTRA and then tweak everything from there (Unless they changed something? I don't play with motion blur on so...)
I also just bought a new mouse since the wheel on my old one died and I fiddled with the settings. I discovered that Windows's mouse speed settings are completely useless and should stay on 6. I used to use 5500 DPI and windows set to 4, now I'm using 2200 DPI and windows set to 6. Granted, I haven't actually tried using the mouse to game yet as I just got it yesterday before going to bed, but when I tried it in VR training I seem to be able to control recoil a little better.
And here are my in-game sensitivities. I'm still trying to tweak them just a little to make them right.
Overall: 0.223
Vehicle: 0.108
Flight: 0.180 (But I don't fly anyways sooooo...)
Scoped: 0.154 (This is for any optic that renders an overlay on your screen, typically anything above 4x)
Aimed: 0.169
Regarding medkits, as someone who considers themselves a medic 'main' they make me sad. Too many times I have gone to try to heal someone, only for them to look look straight at me and chug a healing potion. It doesn't help that they have access to four at a time. There's a reason I don't even use the healing AOE ability any more in favor of the bubble, but that leaves me with medics who refuse to heal me because they just assume that all medics can heal themselves. For a time I even ran with healing potions myself but the C4 is too useful.
Offensively they make me sad too. There's practically no penalty for coming out of a fight with only 1 hp left, so even if I just barely lose to someone then they'll be at full strength in a couple second anyways. It's almost like modern Call of Duty.
EDIT: Be glad you don't have to deal with the pre-nerf ZOE and other shenanigans.
