Thanks for all your replies guys.
Its all kind of what i expected to be honest, and its good to see some others in the same boat.
Ive tried reducing the sensitivity of the mouse, and while it didnt immediately make it noticeably better, i did get a couple more kills, so its helped for sure. The thing is, Warzone is cross platform, so are these xbox players with their controllers really aiming better than i am with a mouse? or is there some sort of handicap system going on here? i'll have to spectate a console player and see.
So the PC is, in brief, a Z270 board, Pentium G4560, a 1070 GPU and 16GB of ram. All seems to run everything fine... however... I'm currently playing on a 1080p 50" plasma at 60Hz, sat on a dining room chair with a piece of wood on my lap with a cheapo, and i mean cheapo keyboard, a logitech "gaming" mouse of some sort, useful as it has extra buttons, why do some games need so many buttons??? and a headset i got from Argos. I can hear you all cringe from here! Its far from ideal i realise, but it actually works alright, though i get a numb arse from the chair.
I have upstairs a desk with a 1440p 27" monitor, though its still only 60Hz. I'd have to re-jig the desk a bit to increase the space for the mouse, which is possible, but the room is connected to my kids bedroom they are 3 and 6 and the little one still wakes in the night, so i wouldnt feel too happy about closing their door, especially since i'll be sat there with headphones on, so i might not hear her wake, and nor would the wife if ive closed the door... i wouldnt be very popular.
So here we are at the crux of the problem, i'm too old. I'm 42 now. I had kids too late, so i'm constantly tired trying to keep up with them, made worse by working from home, and they consume almost all my time. i have enough hobbies that i dont have time to do, so i'm not looking to become "a gamer". I dont generally enjoy life at the moment, and i dont need more frustration in my life.
I'm well aware i will never be "good" and i'm happy with that. If i play CS:Go on deathmatch. If ive had a good match, i'm in the lower middle of the results table. i'll have, say, 15-20 kills. the winner is at 60 odd i think, but i dont tend to look and my mate is usually similar to me... ive died a million times though. And to be honest, i'm alright with that because its still fun. I accept, that considering all the above, ive done alright.
Warzone is growing on my a bit, last night we had a game with four of us playing, all school mates, and we had a right laugh, yeah we were awful, but it was fun. A bit later we lost one of them to parent duties but one of my mates kids joined us. i dunno how old he is, but having someone on the team that knows what they are doing, added a completely different element to it. It was good, it was fun and thats what matters. There was a time, where i was trying to drive a van or something with a mouse and keyboard in "third person view" (which i cant do with a controller in a driving game) which on my own would have been very frustrating, but with everyone laughing and joking at my driving, it was good fun.
Plans are afoot to extend the house, which should give me some man cave space, unless it changes and it becomes more space for the kids crap, so i'll look into making a much better gaming environment, but this online gaming fad with my mates probably would have died out by then. For this reason, i'm reluctant to sink more money into it, though i could get a new mouse and keyboard and maybe glue a better mouse surface to my bit of wood. I'll look up the prices for a faster monitor, as i could put it on the dining room table, but i have no-where to put it when it isnt being used, and although my PC works nicely at 60Hz, presumably it needs a lot more grunt to do the same thing at twice the speed (120Hz)
I'll follow your advice the best i can guys, thanks again.
Mega post, sorry (working from home very bored)
