well over 60 frames is pretty important especially for scout, honestly you can't really improve to become really good without a decent pc.
age shouldn't be an issue, considering some top cs:go players are 30+ and still win big tournaments.

should upload a video or demo so people can see.

but my first impression is that maybe scout isn't for you. try soldier or demo.

I'll leave technical advice about fps and stuttering to people who actually know what they're talking about

Play the game to have fun. If you don't have time to "practice", then play the game whenever you feel like it and try to enjoy yourself. Even pubs will help you improve basic technique like tracking.

I do think your setup is holding you back. Beyond your fps, playing with your mouse on an armrest is probably the single biggest thing that makes your aim inconsistent. Try to find a way to change your setup- it can still be whatever computer you have right now, but get a decent mouse, a decent mousepad, and put it on a flat surface. Do whatever you can to find a way. I'm guessing you play with a fairly low sensitivity because there's not a lot of room on an armrest, so experiment with lowering it.

Don't think that just because you didn't suddenly become much better at i58, your setup isn't affecting you. It will take time for improvement in your setup to take effect in your gameplay.

Obviously getting a 144hz monitor and 300 fps would help you a ton but if you don't want to invest in it that much, just do what you can to cheaply improve your setup and then play the game for fun whenever you feel like it

tbh even having one of your peripherals being bad can totally screw you up. Make sure you have above 60 fps, good ping, and a decent mouse and mousepad. That's all you really need. Alle played on a terrible laptop in prem ,and there are lots of people who have amazing setups that suck ass.

I know its much easier said than done but try not to tilt since that's obviously going to make you play worse

And it's going to be very difficult to play on less than 60fps+ consistently on pretty much any class so it would help you alot if you could get atleast 60fps consistently.

TF2 is not an easy game, TBH if you are not accustom to FPS games it is something that you will have to grind for a good thousand hours or so before you really can even start to stack up against some of the comp players. It doesn't help that you do not get much consistent playtime in the game either as that is a very important aspect. It also sounds like you need to upgrade your rig, having freezing issues and sub 60 fps is not doing you any favors.

If you want to get better at TF2 it sounds like you need to go back to to the basics, learn how to properly aim, learn how to use the games movement, try to understand how the game works at its core. That may be hard if you do not have time but it is probably your best bet at this point.

It is also possible that you are just not naturally good at video games, just like some people are not good at sports or school and if that is the case you will have to put in a lot more hours to get up to a decent level.

i think you need a class that you enjoy playing, and if it is scout, then keep at it.
next, find a sensitivity that you like, and then stick to it for a while and build up the muscle memory

play with bots as a start, if you think human competitive players are too big of a challenge. once you can easily shut down the bots, go practice on some "easy" human targets (like some people in casual/comp matchmaking).

once you feel comfortable enough in these situations, go mge/dm/lobby

also, i don't recommend anything under 60 fps and any ping over 130.

(whining continues)

who cares if youre shit id much rather be shit and have fun with it than be good and invest a ton of time practicing the game every day playing with people whose company you don't enjoy (or not enjoying the game yourself)
imo your mindset should be such that it literally does not matter at all and is just a game to fuck around in and have fun with, especially given that you're admittedly not good you should just be more relaxed about things and not worry about how bad or good you are or if you're improving or not, just have fun with the game and if you're not having fun uninstall it

I found I improved so much on scout when I got critical with myself. When I get outplayed instead of getting frustrated I think how I could have prevented it and learn from these mistakes. Watch demos of yourself playing and think what you could do to play better. Also, try to play with a positive mentality - you can make more mistakes if you are in a bad state of mind.

yes some people just genuinely need to grind a lot of hours to get decent compared to others, as it is in any other hobby in life.
as for a mouse and mouse mat, you need one that preforms consistently, and 4 ingame sens with 800 dpi is probably too high for you because of your flawed aiming style

if you play scout, don't flick, track, keep your eyes on the target and eventually your hand will follow.
at some point youd be able to hit flick shots better but its not something you want to rely on... nothing makes me cringe harder than seeing someone aim at a person, shoot, aim at the floor, then flick at the enemy again - unnecessary effort.

open a bot map and just work on coordinating all of your movement as scout with your aim, so when you move to the right your hand is used to aiming at a certain speed etc..

you don't have room on your desk, don't game on it, getting some solid board and sitting on the floor is better than a tiny desk

sorry for the messy post im way too tired and i know you well enough to know that you can understand me at least partially

btw i suggest dropping your sensitivity to at least 7inches/360

i think it will be good for you to just play about 15-30 minutes of mge and dm then go play a pug/mix/etc

quit while youre ahead

is getting better at tf2 that important to you?

i'm going to go against the grain here. if you've played for 3500 hours and you are genuinely straining to mechanically perform at a high pub level then maybe the game just isn't for you, and no matter the hours you put it you won't get better. not everyone is wired to be able to accomplish any goal. sometimes there are biological or physical/mental factors that hold you back.

now, the hardware could be what is holding you back if your setup is truly as horrible as it seems. if you just jumped on a friends setup at lan, you would be completely unfamiliar with what a good setup feels like and you wouldn't necessarily be able to perform any better than usual. if you are really, really dedicated to the game, get the hardware upgrades that you need to be able to play comfortably (both computer wise and actually having a desk with a space for your mouse) then give yourself a couple of months to see if you improve noticeably. if its not happening at that point you might have to accept the fact that you're not good at the game and there is something fundamental preventing you from improving.

age doesnt matter

Hi, bad at this game, nice to meet you. I'm also bad at this game. I don't know why you're bad but who cares? You're not somebody whose children will starve if you don't perform in game, so play against terrible players and have fun getting rolled. This is the cliche advice to give: if you had fun you won. And it really is true.

That said, un fuck your posture, un fuck your peripherals, get a pc that can run this game, and get a 144hz monitor. You're trying to race a boat that is taking on water.

I was (and kind of am now) in your very situation roughly a year ago. I had to leave my gaming pc behind at home and game on a laptop that barely squeezes out 30-60 fps. But what I did do to become better was practice my mechanics (i.e jumping, mge, rollouts as demo, etc) so that when I went back to my normal setup with a playable framecount, all the mechanics that I had learned would still be there, but I didn't then didn't have crappy hardware holding me back. Now seeing that you have a few issues with some things like having your mouse on your armrest, that much you're going to want to change. Because having a solid setup that doesn't require you to do weird things such as that (or I could reference sideshow having to put his mousepad on a chessboard) will definitely help you in the future. But seeing that you're moving to a new place soon, I'd dedicate as much time as you can right now to getting your aim up to par so that when you move, you'll be able to just pick up right where you left off (even if that requires you to put your keyboard in your lap or something like that).

TL:DR - sink more time now (if that means putting your keyboard in your lap and putting your mouse on your desk) into learning how to aim and track well so that you can be even better when you sit down at a better setup.

putting your mouse on a desk and not the armrest on your chair would help immensely

If you really want to get better you have to practice there is no other way

Play Medic, a class that doesn't require regular DM practice.

its pretty simple

if you suck but you can't practise you will continue to suck

Daigo bless

unnecessary drivel

buy a cheap office chair. If you don't want to spend that much money (I can't imagine the cheapest would be too expensive though, and it'll be useful outside of tf2 as well) buy an even cheaper deck chair or something. You will have a lot more fun playing hitscan with your mouse on a flat surface

Ok you're going to need to suck it up then dog if you can't dedicate time to practice and don't enjoy playing if you don't do well you might as well just uninstall or kys

Come on, take a fucking wooden plank, put it on the armrests and you've got a flat surface for your mouse (and keyboard if you want to use it for that as well).
Why do you have to make this so difficult?
