Alright, I wasn't gonna say anything, but since you've brought it up like at least 3 times now....you're just not that good at this game yet. And don't sweat it, because the vast majority of players I've seen in this flight are average at best. Most of them are pretty bad. Maybe there's a bit of an adjustment to be made for people who play a lot of Halo still, and are expecting certain things to behave slightly differently than they are, I'm not sure. I do know that my brother, who's played a lot more Halo MP than myself over the last 5 years or so, was doing noticeably worse than myself during this Infinite flight. I haven't played Halo MP in quite some time, but I was able to pick this up quite well. Think my average KDA was around 8ish, and I probably won roughly 60% of my matches. The ones I lost were usually due to just having insanely bad teammates. That's from playing almost the entirety of all play sessions minus Sunday, cus I was watching football. 

In that entire time, I encountered maybe like 3 players that I thought had remarkably great aim. Were they PC players? Idk...maybe...maybe they were just better than me. I haven't played anything on a competitive level since BF3, and I've generally played A LOT less PvP over the last several years than I used to, so it stands to reason I'm probably only somewhat above average at this point. 

Don't get me wrong, to me, Halo has always been about starting matches on an even playing field, and so given the option in the full game, I probably would toggle PC crossplay off, to avoid that small percentage of players who are just insane on M&K...but most people really aren't anywhere near that. Lots of PC players will still use controllers, and many may not, but they're simply average players, and there's going to be very very little deviation between your encounters with them, vs encounters with an average console player.

Man, you just nailed it. 100% agree with that. I played a lot this weekend and I did not even realize people where using M/K until I read this thread today...
I think people are over-thinking this and someone is playing better, put this on the M/K instead of anything else.

No doubt, "really" good PC gamers will have an edge at the end with the aiming but I also think it is a very small minority.

I'm sure they will have a feature to disable cross-play. Maybe not launch, but at some point shortly after. I'm not worried about it.

And how exactly could you tell that? From what I could tell, playing the game, I never saw any symbols or other things that marked people as PC/Xbox players. The only times I walked away from a match thinking I must have had at least a few PC players in there, is when I looked at the chat function post-match and there was a lot written in there, as it seems to me people would find more time to quickly use that in-game with a keyboard. Performance wise there was almost never any particular standouts, and I think during the entire weekend I only had a negative KD like 2 times. Either I played against pretty much no PC gamers, or it can't be that big of an issue, because I guarantee you, historically, I'm far from a top tier Halo player. It's a new game. New maps. Some new dynamics with various equipment. Different quirks and behaviors on certain weapons. Maybe different/less aim assist atm. Some people are going to adjust to it quicker, some less so. Just because you were good in Halo 5 doesn't mean it's all down to PC players if you didn't immediately stomp people during this Infinite test. It's ok to admit that sometimes we're just not doing so hot in a game rather than put it all on other factors.

I happen to love Hunt: Showdown. I think it's a dope game. I've put quite a lot of hours into it. Definitely more than a weekend or two. Guess what? I suck balls at it. I'm literally thrilled if I win as little as 2 games in a row. It is what it is.

Odds are a player who's amazing on PC could pick up a controller and smash you just as hard due to their skill and game sense either way.

At the end of the day, why worry about PC players. I am sure you will be able to choose to play with them or not when the game release so no big deal. What you will need to worry about are the console players with the enhanced controllers which will feel like you are playing K/M C players. Either way, it will be the matchmaking putting you closure to people of your skillset that will matter the most which in this flight, I am sure they are not testing.

I believe you might have to high of an expectation of these flights.  I doubt the dev team concertation on the items you present and more looking at stress on the servers and technical issues.  Once this get to a beta stage is when they look to those types of feedback.  I doubt you will see any of your concerns address within these flights as its not on the technical level they are testing but more a personal level.  

For those interested, the list of games that currently support Dolby Vision is very small.

can't remember a time where I didn't own any of the offered games. Somewhat pleased with the month. Almost bought Aaero a few weeks ago.

And here it is!

Took 12 months to come to Game Pass which is a couple of months more than I expected.

Nevertheless, another €25 saved (it's currently on sale lol. Talking about killing sales). The campaign is supposed to be quite decent after all.
