I gave it a try on Blizzard and I gotta say, it's pretty good. Runs good on my PC but the only issue I occur so far is Anti-aliasing needs be fixed. Lower settings or turned off, makes iron sights/sights all fuzzy or pixelated.
I've been playing the beta since last weekend. It's great. It's so much smoother than the previous entries. I'm loving EMP mode. Only issue I've had is lag. Even if you shoot first and get hit markers, you'll look at the killcam and they will have shot first. Doesn't always happen but enough to mention it. I tried playing BLOPS 4 and it's so clunky now. I'll be playing the ground war soon when after I do a few things. The lighting is cool, if you go into a dark building it takes a few seconds to adjust. It's a game changer. There are plenty of angles to shoot from so cover can be a false safety net which is also great.
Just played a few games of ground war, it's pretty cool. Partly a sniper fest but still good. Only issue is lag is god awful and textures don't always load as the should, if it gets really bad it kicks you.
Loving the beta so far. Definitely will win game of the year. Btw, check out all ten of the Call of Duty: Modern Warfare maps revealed so far - lots to be excited about! https://www.vgr.com/all-call-of-duty-modern-warfare-maps-revealed/
