technically speaking m_rawinput 1 should prevent this from happening.

otherwise here is a site that calculates a bunch of things including how fast you can move you mouse before it desyncs from your game window.

https://funender.com/quake/mouse/

Things that affect the issue you're having

DPI : Lower = Less likely
Resolution: Higher = Less Likely
Frame Rate: Higher = Less Likely

some examples
400DPI 3 Sens 1920x1080 160fps
9.75m/s before you start to have that desync issue (you'll actually have to move a bit faster to desync hard enough to switch focus away from the game)

800DPI 1.5 Sens 1920x1080 160fps
4.87m/s

800DPI 1.5 Sens 1920x1080 80fps
2.43m/s

800DPI 1.5 Sens 800x600 80fps
1.01m/s

1600DPI 0.75 Sens 800x600 80fps
0.51m/s

Probably unwanted explaination:

TF2 counts basically anything that's sub 20ms ping as "5 ping" on the scoreboard. LAN ping would literally be server tick rate + sub 1ms or ~16ms delay with 0 jitter and 0 loss you also have the advantage of having a significantly better server that isn't glutted with several other game servers. Having say 19ms ping would add a obvious delay especially on a server that's likely has less dedicated resources while also taking on network traffic from more sources for other servers.

Forgot who said it (probably corsa though) "if I had 5 ping I would've dodged that"

"goofy shit to see if it works"
You need to understand why something worked or didn't work.

"have ringers"
you can still individually review yourself

"maybe throw because you're bored"
stop playing then cause it's a literal waste of everyone's time.

"when match time comes around that's when things actually matter"
this is why you should review before. I mean it helps if you're going into Thursday but not Tuesday. Plus you get to pick your scrims not your matches. Ex. MAL would probably learn a lot more from reviewing a scrim against Mentality or New God Flow than they would in a match vs Froyo. Plus doing something like this means you not only have to do a map review you also have to do a STV review separately which is perfectly fine it just requires a fair chunk more time.

"he best demos to watch and i imagine that these players feel the same way"
They might feel that way but I still highly doubt many players in invite actually review their own demos or STV team demos match or not on a weekly basis.

While I do agree with you in that a lot of people are seriously under estimating the amount of time and effort Invite players put into playing. Have you considered Invite in general is putting in the wrong kind of effort or to little of a different kind? How many full teams in Invite review scrim STVs? How many individual players in Invite review their own demos and or VODs? I'd honestly be surprised if more than a handful of players or teams in Invite did this and I'd be in utter disbelief if any team in invite did all those things on a weekly basis. It's not like it takes a massive amount of time either a map review can be combined with a STV review and realistically you only need to review a couple rounds.

While I've never played invite the few times I was trying to improve in 6s in general I asked several invite players if I could get a demo of them playing so I could review it. You know the answer I got? "I don't record demos outside of matches" most of these players didn't stream at the time either and the few who did most of them didn't have archiving enabled on twitch. I'm assuming it's either the same or worse now.

Kalkin I can't take this trolling stop.

nah shdsteel almost literally bathes in spare PC parts.

What are the actual stats of the MP5?

From what I'm reading this weapon is useless and doesn't have any real niche.

MP5 vs MP7

Pluses

• Less noise
  
• Faster move speed (about 8% faster move speed)

Minuses

• Less Damage (27 vs 29)
  
• More Spread while moving possibly ingeneral (makes no sense at all the silenced weapons in the game have less spread... it will have the worst move spread of all SMGs...)

Same

• Cost
  
• Magazine Size and total ammo
  
• Kill Award
  
• Recoil (both say "85" which is pretty dumb I thought most silenced weapons had less recoil vs stock)
  
• Penetration
  
• "Stopping Power"

basically the MP5 forces you to play more like if you had an actual rifle with terrible damage. The only thing I could think of for usage is going for a "quiet" loadout or something that's just plain dumb.

Yes and No. Technically interpolation would also be used if the server is unable to send a frame in the timespan expected.

example

you have set

cl_updaterate 66
cl_cmdrate 65
cl_interp_ratio 1
cl_interp .0152 

All is well and good assuming the server constantly gets 66 updates to you (or more) 100% of the time, but the server may not be able to do so for various reasons i.e. Packet Loss, The server is crap and can't keep up, the server (or any hop between you and the server) is being attacked and causing wildly fluctuating packet times thus delaying updates from the server to you, the game you're playing isn't the most stable thing, etc. Say you're suddenly getting only 60 updates per second but no packet loss your interp would need to be "cl_interp 0.0167" in order to be applied correctly.

Typically speaking the higher your ping the more hops and distance you have between yourself and the server which means there are more points that failure or delays can happen.

To my (admittedly rather limited) knowledge cl_interp_ratio is for update drops (either via the server or packetloss) while cl_interp is for delays. (Technically they both apply to both but more so to one than the other) Most people have more issues with delays than packetloss assuming a wired connection. To add to this basically every server I've played at least fluctated from ~64 updates to ~67 updates per second.

It appears that StreamLabs OBS was set to "Auto" for server (I swear I had this manually set before, I know in my early July streams I definitely did cause I was still using regular OBS and checked that setting hasn't changed). I manually set it to Chicago US East and issue didn't occur the last time I streamed. According to streamlabs "Auto" is the best setting cause it automatically pick the "best" server lol more likely it picks the 1st "acceptable" server.

That's not the point of the question though...

He's asking for what would give him the best hit registration / most enjoyable experience.

Regardless of what class you play.

cl_updaterate 66
cl_cmdrate 65 

according to mastercoms cl_cmdrate is set lower than cl_updaterate to have smoothing be applied to server updates and not client updates *my understanding of this could be wrong*

If you main a projectile/particle class (Soldier, Demo, Pyro and Medic)

cl_interp_ratio 1
cl_interp .0152 (a value of 0 would be fine as well)

If you main a hitscan class (Scout, Heavy, Sniper and Spy)

cl_interp_ratio 2 (possibly higher)
cl_interp .0228 (possibly higher but this should work fine)

or (for basically the same thing)

cl_interp_ratio 3
cl_interp .0152

I didn't add Engineer to either list cause I can see an argument both ways. On 1 hand a low interp value would be better for Rescue Ranger + less latency to hitting a sentry with a wrench + less latency to start building on the other hand a higher interp setting would give better overall hit registration for PvP melee and hitscan weapons.

mastercomfig seems to generally recommend these other settings as well

net_compresspackets 1
net_compresspackets_minsize 128
rate 196608 // 1.57 Mbps default rate from CS:GO
net_splitpacket_maxrate 196608
net_splitrate 1 // How many packets to split per frame
net_maxcleartime 0.020346

mastercomfig seems to have several settings for the below but I picked out the "balanced" ones for you.

net_maxroutable 1200
net_maxfragments 1200

I lucked out so hard with this. My work was about to throw away a Steelcase Leap from ~2004 because it was old and covered in dirt but otherwise 100% fine (no tearing, nothing was falling off, original parts, height/arm/lumbar adjustments all still worked). Asked my manager if I could just take it home and they were like "why? thing has been sitting for over a decade... whatever go ahead." vacuumed it for like 2 hours and it's basically brand new. The chair costed like $2000 when the company bought it...

Easily the most comfortable chair I've ever used.

This is an advantage I do have. I work for the ISP and have direct management access to every hop from my house to the border of my ISPs network until it's handed off to Cogent which has more than enough bandwidth at least to the edge of Chicago. Using tools to test speeds to Twitch's Chicago server suggest I should have significant upstream headroom over my current bitrate, but that may not be indicative of all days/hours or even minutes so I'll try a different server and see how it goes.
