I've been playing online FPSs for years now, but I've always been absolutely terrible at them. I can maybe get a 1:1 K:D ratio on a good round, but my average is probably closer to 1:3 or 1:4. This has been pretty consistent in every FPS I've played over the years. I'm not sure what I'm really doing wrong. I use cover. I try to flank with my teammates. I throw grenades to flush enemies out of cover. But somehow it always seems like they're faster, more accurate, better able to get the drop on me.
Is it just because I only play them for a few weeks or months before moving on? Is this something that gets better with practice, or do I have some kind of undiagnosed motor deficiency?
Alas, I pretty much entirely play from my wrist out of necessity. As soon as my arm gets involved, my precision goes waaay way down. It's a life long pathological thing that affects many areas of my life. :( In FPSes I usually rely on positioning and tactics to get ok scores. Weirdly, the one game in which I was unreasonably good at shooting was Battlefield 1. Absolutely no idea, did nothing particularly different. Just me and my open sights SMLE III routinely getting long ranged headshots or quick aim close ranged kills. It just clicked with me.
I remember in TF2 I played pyro and had a mouse sensitivity of 12, compared to my sniper friend's 0.7 (who used his whole arm and mousepad area).
Whatever is comfortable and works for you is also really all that matters in terms of aim. That being said, being a pyro on 12 sens is such a pyro thing
Quite a hit of nostalgia. I download TF2 maybe once every couple of years to faff about for a bit.
