Please recommend some settings for me.

I feel like the game runs really jumpy on any server I’m on. I can’t tell much of a difference between a server where my ping is 50 and one where it is 150. I find myself losing a lot of gun battles because my opponent seems to be jittering/stopping/flashing around on my screen. I’ve edited my game’s config file as below. I run the game on 1920x1200 resolution and have tried fantastic, beautiful, good and fastest settings.

And feel like I have stripped it clean. However, I’m not positive I’m clear on what each one of those does.

Here are some PC specs.

Operating System

So any help would be appreciated. I’m thinking that maybe it’s just netcode and I can quit beating myself up over this. However, I just don’t feel like I’m on an even playing field with some of the guys I’ve been in battle with. Thanks in advance.
